Engine block

The engine block is made of nodular cast iron and is of stiff and durable design to absorb internal forces. The engine block carries the underslung crankshaft. The nodular cast iron main bearing caps are fixed from below by two hydraulically tensioned studs. The caps are fixed sideways by hydraulically tensioned horizontal side studs. Together they provide a rigid crankshaft bearing. The inlet air receiver and the cooling water and lubricating oil channels are integrated into the engine block. The engine is provided with an oil sump, mounted against the engine block and sealed by an o-ring gasket.

Crankshaft

The crankshaft is forged from one piece of high tensile steel. Counterweights are fitted on the crankshaft webs. The high degree of balancing results in an even and thick oil film for all bearings. The main bearings and the crankpin bearings have a steel backing and a soft running layer with excellent corrosion resistance.

Connecting rod

The connecting rod is of the drop forged, totally machined type. The connecting rod is of three-piece design with a horizontal split at the crankpin bearing and a flanged connection to the rod. The oil supply for the piston cooling, gudgeon pin ▇▇▇▇ and piston skirt lubrication takes place through a single drilling in the connecting rod.

Cylinder liner

The cylinder liner is centrifugally cast iron with special alloy elements to create wear resistance and high strength. The liner is of stiff bore cooled collar design and supported symmetrically at the top of the engine block. It is equipped with an anti-polishing ring at the top, preventing bore polishing.

Piston

The piston consists of an oil cooled steel crown bolted on to a nodular cast iron skirt. The piston crown has two compression rings and one oil scraper ring. The piston skirt and cylinder liner are lubricated by a patented pressurized lubricating system utilizing lubricating nozzles in the piston skirt. This system ensures excellent running behavior, and constant low lubrication oil consumption.

Cylinder head

The cylinder head is made of nodular cast iron. Ample height and the stiff design allow only four hydraulically tightened studs to fix the cylinder head on to the cylinder block/liner. Each cylinder head has two inlet and two exhaust valves, all equipped with rotators. The exhaust valves are made of Nimonic and the exhaust valve seat rings are water cooled.

Camshaft and valve mechanism

The cams are integrated in the drop forged camshaft material. The bearing journals are made of separate pieces that are fitted to the camshaft sections by means of flanged connections. This design allows lateral dismantling of the camshaft sections. The camshaft bearings are located in integrated bores in the engine block casting. The camshaft is driven from the crankshaft through a fully integrated gear train.

Fuel Oil System

All the high pressure fuel injection equipment is located in a closed compartment with a removable cover (“hot box”), providing maximum reliability and safety for preheated heavy fuel.

The fuel system comprises the following equipment:

	•		Low pressure pipes made of steel

	•		High pressure pipes, double wall with common leak alarm

	•		Injection pumps, individual for each cylinder

	•		Pneumatic stop cylinder at each injection pump

	•		Fuel injector in each cylinder

	•		Fuel limiter to limit smoke at start up

	•		Solenoid valve for fuel limiter at start up

Lubricating Oil System

The lubricating oil system lubricates the main moving parts of the engine and also cools the piston tops. The engine has a wet lubricating oil sump.

The lubricating oil system comprises the following equipment:

	•		Pipes made of steel

Generator construction

The generator is designed to operate together with reciprocating engines. The stator frame is constructed with a rigid welded steel structure. The stator core is build of thin electric steel sheet laminations. The rotor consists of a shaft and salient pole type main revolving field.

The generator achieves very high efficiency because of the exceptional thermal conductivity created by the tight fit between the coils and the stator core.

Terminals

The six stator winding ends are brought to the terminal boxes on the generator sides. Terminals for monitoring and auxiliary equipment have separate terminal boxes.

Damper winding

The generator is provided with a damper winding for parallel operation with other generators and with a separate power grid.

Shaft and bearing

The generator is horizontally mounted and provided with two sleeve bearings. The generator rotor is designed to minimise the effect of torsion rotor oscillations due to system disturbances and rapid load changes.

Excitation

The exciter is of the brushless type with a rotating armature/rectifier assembled on the same shaft as the main generator rotating armature. The exciter field is controlled by the automatic voltage regulator (AVR). The rectifiers are of the silicon diode type in a full wave bridge arrangement. The rotating armature and stationary field of the exciter are insulated with Class F materials.

Cooling (air cooled)

The generator is air cooled. A fan mounted on the generator shaft takes cooling air from the engine hall, through washable filters, and passes it through the generator.

Automatic voltage regulator

The voltage regulator is of a completely solid state type for control of generator voltage by means of controlling the exciter field. The regulator controls the generator exciter field as required to maintain a constant and stable generator output voltage. (The AVR is installed in the engine generator set control panel).

8 Fastening equipment (set)

Equipment for fastening the engine and generator to the common base frame, including: bolts nuts, washers and steel chocks.

A1.4 ELASTIC MOUNTING

The common base frame is mounted on elastic elements to reduce the transmission of dynamic forces to the foundation. The size of the foundation is thereby reduced compared with traditional rigid type generator set mounting to foundations. With this elastic mounting, the common base frame is completely isolated from the foundation and thus not affected by the difference in thermal expansion coefficient between the foundation and the common base frame. The structure borne noise level is also greatly reduced with an elastic mounting design.

8 Steel springs (set)

Steel spring type vibration isolation units are installed between the common base frame and the steel foundation. The number of steel spring units for each type of generator set is determined by the weight of the generating set and an analysis of the natural frequency of the rigid body. A fitting plate is installed between the common base frame and the steel spring packages to adjust to the level of the surface of the foundation.

A1.5 COUPLING

8 Flexible coupling

A flexible coupling between the engine flywheel and the generator transmits the torque from the engine to the generator. By using a flexible coupling the crankshaft is not loaded by any external bending forces. The elements in the coupling are made of rubber.

A4		AUTOMATION SYSTEM

Control and Supervision Concept for Wärtsilä Power Barge

The control and supervision system is designed for safe, reliable, efficient and easy operation of the generating sets, their associated auxiliaries and electrical systems. A modular design allows easy extension of the system.

The Power Barge can be controlled from either the Wärtsilä Operator’s Interface System (WOIS workstations, CWA901), or from the central control panel/common and generating set sections (CFA 901 and CFC0_1).

The WOIS workstation, common and generating set control panels are located in the control room where all the main supervision of the plant takes place. The generating set control consists of two control panels, the central generating set control panel and the local generating set control panel, which is placed next to the generating set.

Control modes

The following control modes are available for the generating set control.

By increasing or decreasing the engine fuel supply, the active power can be controlled in:

	•		MW mode — the generating set power is maintained at a preset value irrespective of system load or frequency. This is the typical operating mode for a base load Power Barge supplying an infinite grid.

	•		Isochronous load sharing — the generating set shares the load with other generating sets at a constant frequency. This is the typical operating mode when running in isolation from the grid. This operating mode requires that all the generating sets have speed controllers suitable for isochronous load sharing.

	•		Speed droop mode — the generating set shares the load with the grid or other generating sets according to a speed droop curve. This is the typical operating mode for smaller grids or in island operation.

By increasing or decreasing the generator voltage, the reactive power can be controlled in:

	•		Constant Power Factor control — the generating sets power factor is maintained at a preset value and any changes are produced by the grid or other generating sets. This is the typical operating mode for a base load Power Barge supplying an infinite grid.

	•		Voltage droop compensation control — The generating set will share the reactive load with the other generating sets based on digital communication lines between the AVR’s when running in island mode. This is the typical operating mode when running in isolation from the grid. This operating mode requires that all the generating sets have voltage controllers suitable for voltage droop compensation control.

	•		Voltage droop mode — the generating set will share the reactive load with the grid and other generating sets equally in relation to the size of the units. This is the typical operating mode for smaller grids or in island operation.

The system will automatically switch the operating mode based on the “parallel with grid” signal. In Auto mode the setting values for active and reactive power will be according to operator input in WOIS workstation, while in Manual mode they are determined by the switches in the control panel.

WOIS workstation

		The Power Barge is controlled and supervised from the Wärtsilä Operator Interface System (WOIS workstation). All actions necessary for the normal operation, such as start and stop of the generating sets, load increase and load reduction are activated and supervised via the WOIS workstation, using a mouse, keyboard and display. The operator can also supervise key data from the plant such as various temperatures and pressures as well as measurements of electrical variables such as generator power, voltage and frequency. The WOIS workstation also includes a hardcopy laser printer.

		WOIS workstation includes the following functionality:

	•		Process status displays, where the status and operation of the processes are displayed using various dynamic objects, such as images of pumps, valves and other components and units. The status of these objects is displayed graphically. By interacting with an object, the function and operational status can be displayed.

	•		Process trends can be displayed as a free combination of six (6) measured values such as pressures, temperatures, speed, generating set load, etc. The operator may combine the values of interest in one graph to get a good view of the total process for further analysing. The trends are stored for up to 180 days, and the operator may call back a trend for any time interval within these limits.

	•		An alarm banner in the uppermost part of the displays informs about the latest occurred alarm. The active alarm list informs the operator of possible problems in the process. An alarm will remain on the active alarm list until the process has returned to normal state and the alarm has been acknowledged. Historical alarm and event lists can be called up for further evaluation of events.

	•		Any of the displays and the alarm list can be printed to the hard copy printer.

A standby fuel fired boiler is supplied for backup use. The system is designed based on an “N+1 redundancy principle” including the fuel fired boiler.

Steam flows from the heat recovery boilers to a steam header for distribution to the steam consumers in the plant. A non-return valve on the steam outlet of the drum prevents backflow when the boiler is not in use. Condensate is collected in the feed water tank and returned to the boilers by the feed water pumps.

A fuel fired boiler is provided to generate steam when the engines are not running or when the exhaust gas boilers require maintenance.

Exhaust gas boiler

The exhaust gas boiler is a verticall smoke tube type.

Lihir Power Barge Fire Protection


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 2(15)

GENERAL

This description is specifying extended protection compared to the basic protection provided by Wartsila.

The system is based mainly on NFPA principles like ▇▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇ and NFPA14 but utilising european standards for equipment.

This shall not overrule the engine, module and civil design (power house building) used by Wartsila and the experience of Wartsila building similar power plants.

The engine room shall be provided with ring pipe with hydrant connections. Additionally, the mobile foam units are to be provided. For immediate action against small local fires the power house is equipped with many 6 kg and 12 kg dry powder extinguishers at strategic locations and 5 kg CO2 extinguishers for electrical fires. Additionally the engines are protected with fixed water mist system utilising high pressure water supply (approx 100 bar). The system shall be built mainly for the protection of engine frontal piping and turbochargers.

The fire main will be built aroung the barge deck providing main supply of fire water for different applications.

Recommendations

When recommended the fire fighting equipments have following aspects been noticed:

	•		Skilled personnel attend the Power Plant 24 hours a day.

	•		Experience on execution of similar Power Plants

	•		Power Generation not to be interrupted due to false alarms and failures in an automatic system.

	•		Regular training of personnel in correct operating procedures

	•		Plant shall be well maintained and kept in good order

	•		Maintenance work including welding and cutting shall be done with appropriate precautions and instructions

	•		Installed fire protection equipment shall be maintained and perioidically tested


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 3(15)

Fire water pumps

In the Fire Fighting Water pump room, there are two fire pumps, one driven by diesel engine and the other by an electric motor. The pumps supply water from the Fire Fighting Water tank for the standpipe system and fire hydrants.

The pumps shall locate in a room separated with fire rated wall and protected with wet pipe sprinklers.

Either one of these centrifugal pumps must alone be able to deliver the required amount of water. At the rated flow, the pressure produced by the pumps must be at least 8 bar. The final pressure should be evaluated according to system requirements.

Electric jockey pump in the system automatically maintains system pressure in the pipeline. If the jockey pump can not keep the pressure, the pump control system, brings the fire pump or pumps into action automatically.

The selected capacity of one fire water pump is 150 m³/h (2500 l/min).

The offered pumps shall be hydraulically sized according to the NFPA20 standard (Not less than 150 % of rated capacity at not less than 65 % of total rated head). Otherwise the pumps will follow CEA4001 standard.

Both pumps shall have fire water suction strainers with pressure difference measurement. The fire pump test line with flow measurement device shall return the flow after the pumps to the fire water tanks for testing. During these perioidical tests the pressure loss over suction strainers shall be also checked and if necessary the strainers shall be cleaned and cause for blockage to be examined.


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 4(15)

Fire water tank capacity

The Fire Fighting Water tank supplies the hoses, mobile foam units with adequate amount of water. The water capacity of the Fire Fighting Water tank must be at least 300 m³. This provides 120 min protection of a 150 m³/h (2500 l/min) flow demand. ▇▇▇▇▇ sizing is based on simultaneous operation of the engine water mist system up to group of four engines (approx 600 l/min) and hose stream allowance of 1900 l/min or in the otherhand foaming of the 600 m³ HFO day tank (approx 500 l/min) and hose stream allowance of 1900 l/min.

RECOMMENDATION FOR FIRE DETECTION SYSTEM

General

This specification describes the practises applied and recommended in the design of fire alarm system. It provides guidelines for dividing the plant into fire alarm zones (groups), for selecting fire alarm system, detectors and alarm devices, for locating the devices, and for arranging the fire detection and fire alarm signalling loops.

The detection shall be based on EN54 standard.

Systems may differ in product assortment and allowed configurations. A fire alarm system consists of the following main components (see Figure 1):

	¥		a fire alarm center including a supervision unit, a display unit, input and output terminal units, a power supply unit, and a message transfer unit

	¥		fire detectors and manual call points connected to the fire alarm center

	¥		alarm devices (bells, sirens, flashing lights) connected to the fire alarm center

Figure 1. A principle figure about the components of a fire alarm system as it could appear in a power plant


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 11(15)

Figure 1 represents an addressable system. The detectors are arranged in closed loops with disconnecting devices (separate disconnectors or isolator bases) at appropriate intervals for isolation of faulty sections at line fault. The hazardous area (area containing inflammable gases, liquids or vapors) has detectors of conventional type, which are connected to the fire alarm center via an address unit.

When designing a fire alarm system, the following basic principles should be considered:

	¥		The fire alarm center shall be placed in a continuously manned room. In a power plant this is the control room.

	¥		The supervised rooms should be divided into alarm zones to ease locating the fire.

	¥		Every room must be provided with a suitable amount and type of detectors.

	¥		Alarm bells, sirens and flashing lights must be situated so that they can be heard or seen everywhere inside and where needed outside the buildings.

	¥		An average ambient sound level greater than 105 dBA shall require the use of a visible notification appliances

Selecting fire alarm system

This specification gives no directives regarding supplier or type of fire alarm system. An addressable system is recommended.

Fire alarm zones

The purpose with fire alarm zones is to group the fire detectors and in that way ease the fire location at an alarm.

At least the following areas should be defined as separate fire alarm zones:

	¥		Separate buildings

	¥		Separate floors (except stairways which may encompass several floors)

	¥		Rooms separated by fire walls

	¥		Areas of different fire classes

	¥		Rooms or areas of essentially different heights

	¥		Rooms that cannot be accessed without passing through other zones


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 12(15)

Designing fire detection system

Selecting fire detectors

The basic principle is to install the type and amount of fire detectors that gives earliest possible fire detection without causing false alarms during normal operation conditions.

Optical smoke detectors are recommended, except in workshops and similar rooms where smoke may appear as a result of the normal use of the room. Use differential maximum heat detectors in rooms where smoke detectors cannot be used.

Smoke detectors are suitable for the engine room, the auxiliary hall, the switchgear rooms, offices, stores and control rooms.

The optical smoke detectors detect visible smoke particles, either based on their light reflectance or light absorption. Ion detectors are activated at an increased electrical ionization resistance and they are able to detect even invisible smoke.

Heat detectors are immune to exhaust gas and welding smoke and are therefore suitable for use in the workshop.

The maximal heat detectors operate in cases where a maximum temperature is exceeded. The differential detectors operate in cases where the temperature rises too fast. The differential maximal detectors operate in both cases.

Flame detectors may easily cause false alarms and are not recommended.

Locating manual call points

In a manual alarm device, the fire alarm is activated with a push button. Normally the button is protected with a cover that can be crushed.

Push buttons for activating fire alarms manually should be placed close to each exit and close to the fire alarm panel or alarm center. Each fire detection loop must have at least one push button.


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 13(15)

Arranging fire detection loops

General principles

The fire detectors and fire call buttons are located along one or more closed loops starting and ending in the fire alarm center. See Figure 2. In addressable systems, a fire alarm loop may extend over several alarm zones.

Rules for locating disconnecting devices

Each detection loop will be partitioned by a number of disconnecting devices. The disconnecting devices may be installed as separate devices or included in the detector bases as “isolator bases”. At a line break or short circuit on the loop, the faulty section is isolated at the two closest disconnecting devices. The other detectors on the loop will stay in contact with the fire center along either end of the loop.

Figure 2. The fire detection loops on the bottom floor of a power house (BLN901 = fire alarm center)

Cable recommendation for detection loops

The cable with copper wires (2x0.8 mm indoors and 4x0.8mm in outdoor circuitries) that fulfil the fire condition requirements of IEC 332-1 should be used.


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 14(15)

Alarm signaling system

The following types of alarm signaling devices will be used:

	¥		Alarm bells (92 – 95 dB)

	¥		Flashing lights (1 Hz, 1W)

	¥		Alarm sirens (about 115 dB) where feasible

Flashing light signals (1 - 2 Hz) are obligatory in the engine hall and auxiliary hall.

Locating alarm devices

Principles for placing the alarm signal devices:


Engine room		Alarm devices (flashing lights) visible between every engine.

Control room		One audible alarm device (alarm ▇▇▇▇).

Other rooms		Audible alarm devices should be placed so that they can be heard in all rooms where people stay more than temporarily. The sound level should be at least 15 dBA above the average sound level in the room or 5 dBA above the maximum sound having a duration of at least 60 seconds whichever is greater, measured 1.5 m above the floor.

Outdoors		One audible alarm device on each side of the power house.

Arranging fire alarm signaling loops

All alarm devices everywhere in the plant should be activated at a fire alarm.

The fire alarm loops should be arranged so that a fault message is obtained at cable break or short circuit.


		Doc. Classification: Internal DocID: DBAB103090 Revision: - 15(15)

Figure 3. Example of fire alarm devices in a power house

Cable recommendations for alarm signaling loops

The cables with solid copper conductors (3x1.5 mm² in the power house, and 2x2.5 mm² between buildings) that fulfil the fire condition requirements of IEC 332-1 have been used.

Fire alarm centre

Arranging power supply

There will be at least two independent power supplies:

	¥		230 VAC taken from the LV switchgear (or public grid)

	¥		One or more batteries (generally 24 VDC) with battery charger.

Each of them must be able to feed the power required when the system is in alarm state and the current for 0,5 hours in alarm state.

Connecting to other systems

Available potential free contacts should be arranged so as to open at a fire alarm or fault (normally closed). The contacts can be used for transferring alarm and fault signals to the plant control system.

Plant control system

Alarm and fault signals can be used for activating alarm and possible consequential actions in the plant control system. The programmed fire alarm procedures should be agreed upon with the plant owner.

Plant ventilation system

The plant ventilation system is controlled according to engine operation. In Auto-mode, fire alarms may be used for stopping the engines but the procedures should be agreed with the customer.

Electrical Power Test

4.1

General

The Electrical Power Test is preferably done concurrently with the Heat Rate Test.

The engines involved in the test shall run for 2 (two) hours at full load prior to the start of the test in order to achieve stable conditions in all engine components and external systems.

Because there can be major variations in the ambient conditions during the full test period, it is important to split the full test period into shorter hourly test periods. These hourly test periods are then used to calculate the average of the full test. Please note that under no circumstances should an average of the ambient conditions prevailing over the full test period be used for the adjustment.

For accuracy of the test it is important that all measurement readings are taken simultaneously. This can be best achieved by a cordless communication system.

The required measurements are done on an hourly basis and the readings recorded on a form. The period can differ somewhat from one hour without affecting the accuracy of the test. The electrical power is calculated from the produced electrical energy during each test period. The actual electrical power and actual fuel consumed is naturally the sum of all hourly test periods.

The guaranteed electrical power and heat rate for each hourly test period is adjusted for the ambient conditions prevailing and measured at the start of each hourly test period.
The final guaranteed power and heat rate during the full test, is the average of the adjusted powers and the average of the recalculated heat rates, which are calculated separately for each hourly test period.

The point of measurement depends on the agreement between the Contractor and Owner.

Power factor during the test shall be equal to or above 0,8. No corrections will be made for power factors higher than 0,8.

Only equipment required for normal operation of the plant shall be running during the test. Any redundant equipment shall be shut down. A list detailing which consumers are connected during the test is included in section 6.

The substitute reference conditions are described in Exhibit B — Performance Guarantees / Figures.

4.2

Adjustment of electrical power for ambient conditions

A Diesel engine will react on the ambient conditions in a very complicated manner. The ISO 15550 and ISO 3046 standards give a uniformed way to adjust performance from one condition to another. The adjustment is always done via reference conditions that can be either the standard reference conditions as stipulated in ISO 15550:2002 clause 5 or the substitute reference conditions declared by the engine manufacturer.

The formulas below are according to ISO 3046.

Exponent values are from ISO 3046-1:2002 (E), Table 2 for
Engine type: Diesel engines and dual fuel compression-ignition engines operating on liquid fuel, Conditions: Turbocharged with charge air cooling, Low and medium speed four-stroke engines, Formula reference: D

Exponent values are: m = 0,7 n = 1,2 s = 1


		Doc. Classification: DocID: WDAAA245063 Revision: c.9 6(11)

The Energy is measured using PMU (Power Monitoring Measuring Unit) or a separate EMU(Energy Measuring Unit) depending on the point of measurement. The Power is then calculated from the Energy for each test period. These are then used to calculate the average power for the Electrical Power Test and also for the Heat rate test, if being done concurrently.

P = E_p / tt

Where E_p = E_g or E_mv or E_hv dependent on the agreed point of measurement.

E_mv = E_g — E_o and E_hv = E_mv — E_su

4.3

Measurement tolerances in electrical power test

The measurement tolerances will cause a measurement uncertainty in the measured electrical power. The components involved are the measuring transformers and the power measuring unit, and in some special cases only the energy measuring unit. The typical tolerance will be in the range of ± 0,3 % to 1,0 %.

Tolerance usage is according to ISO 3046-3:2002 (E), clause 4.4.4

4.4 Electrical Power

The electrical power is between

The test is successfully passed if P_max > P_guaranteed

The contractor is entitled to a possible bonus if P_min > P_guaranteed

If P_guaranteed is between P_min and P_max, neither penalty nor bonus will apply.

Heat rate test

5.1

General

The Heat Rate Test is preferably done concurrently with the Electrical Power Test.

The engines involved in the test shall run for 2 (two) hours at full load prior to the start of the test in order to achieve stable conditions in all engine components and external systems.

The guaranteed electrical power and heat rate for each hourly test period is adjusted for the ambient conditions prevailing and measured at the start of each hourly test period.

The final guaranteed power and heat rate during the full test, is the average of the adjusted powers and the average of the recalculated heat rates, which are calculated separately for each hourly test period.

The point of measurement depends on the agreement between the Contractor and Owner.

Fuel samples are taken before and after the test. If samples are taken during the test, then the amount of samples and spillage is to be deducted from the measured fuel consumption. Two samples are taken at each sampling time. Both samples are sealed and signed, one is kept as a reference and the other is sent to an independent laboratory for analysis.

The analysis should cover all the items stipulated in the fuel specification in agreement between the contractor and owner. The laboratory report shall include LHV and the tolerance on the LHV. The average LHV of the samples is used in all calculations.

Power factor during the test shall be equal to or above 0,8. No corrections will be made for power factors higher than 0,8.


The standard reference conditions are :
Ambient air barometric pressure	=	100 kPa
Ambient air temperature	=	25 C
LT Coolant temperature	=	25 C

Recalculation of heat rate for ambient conditions

A Diesel engine will react on the ambient conditions in a very complicated manner. The ISO 15550 and ISO 3046 standards give a uniformed way to adjust performance from one condition to another.

3		Definitions

		Density of lubricating oil changes as a function of temperature. This must be taken into account when measuring lubricating oil consumption. Lubricating oil density is normally given at 15 ^oC temperature and the product specific value can be found from the Product Data Sheet of the lubricating oil in question. Following formula is used when calculating lubricating oil density at different temperature.

		DocID: DAAB184367		Revision: b.6				2(2)



4		Duration

		The lube oil consumption test will be run during a minimum 48 h period.

5		Lube Oil Consumption Measurements

		If possible its recommended to run other tests before this test to have the engine running hours as high as possible. 100 running hours or more will give more reliable lube oil consumption figures.

		The engines should be run at a minimum of 85 % of maximum site power during the test.

		The lube oil separator should not run during the Lube Oil consumption test, because the Lube Oil consumption guarantee is based on the Engine consumption only, otherwise the oil discharged by the separator would be included in the engine oil consumption. However the maximum recommended time for running without Separator and new Lube Oil is 48 Hours on Heavy Fuel Oil. If longer Lube Oil test intervals is required, the Lube Oil test must be done running on LFO, to prevent that the oil quality deteriorates below limits.

		The temperature of the oil and the amount of air bubbles in the oil will affect the readings. In order to improve the accuracy of the measurements the conditions at the beginning and end of the test should be kept similar. The engine should run for a minimum of two hours at minimum 85 % load before the first reading is taken. The reading is taken 20 min after the engine has been stopped according to the normal shut down procedure. The final reading is similarly taken 20 min after the engine has stopped after the test. All pumps and separators in the lube oil system will be stopped at the same time as the engine.

		The level of oil will be recorded before and after the test with the dipstick in the engine oil sump. The Lube Oil consumption is calculated based on the differences on the oil level. The consumed oil amount is a function of the dipstick level difference and can be found as a reference document to the project specific test procedures.

1 Objective

The objective of the Stack Emission Test is to verify compliance with the Stack Emissions Guarantee set forth in the Agreement.

2 Testing Procedures and Conditions

The emission performance figures provided in the Stack Emission Guarantee are valid for the emission measurement methods and standards specified in the emission guarantee document. This document specifies testing procedures and additional requirements to be followed during the tests in order for the stack emission guarantees to be valid.

Some measurement methods and standards allow different variations of how the measurements are performed for example depending on application. If the Stack Emission Guarantees or this document specifies the use of a specific variation to the method, this recommendation needs to be strictly adhered to. Any other variations of the method or use of an alternative method must be agreed mutually between both parties.

Compliance with the Stack Emission Guarantee will be demonstrated as far as practicable concurrently with the other performance tests of the Plant. Similar engines running on same conditions have same emission performance. In plants having multiple engines appropriate amount of engines will be tested and plant average stack emission will be calculated based on these measurements. This calculated plant average emission will be seen sufficient for demonstrating the fulfilment of Stack Emissions Guarantee. An accredited, preferably third party, measurement consultant will be assigned to carry out the measurements and to issue a Stack Emission Test report.

The flue gas stack emission measurements will be performed at 100% engine power at stable running of the Engine if not otherwise mutually agreed. Prior to start of the flue gas emission (stack) measurements, the Engine shall be operated for a minimum of two hours at 100% load in order to obtain steady state conditions. Contractor shall have the right to inspect the Engines to be tested prior to the test and conduct corrective adjustments, repairs, etc., if needed.

Doc. Classification: Confidential


		DocID: DAAB195899		Revision: b.10				2(4)

In the flue gas (stack) emission measurements, sufficiently long sampling periods and a sufficient number of samples shall be taken in order to get statistically representative results. Based on Wärtsilä experience, the following minimum requirements apply:

	o		Gaseous components (analyser procedures): Emissions are calculated based on a minimum averaging time of 60 minutes. The period can differ somewhat from one hour without affecting the accuracy of the test.

	o		Gaseous components (discrete sampling): The emissions are calculated based on the average of minimum three samples. A minimum sampling time of 30 minutes per sample is recommended. Note that some methods may necessitate shorter sampling times. In such cases, the sampling times shall be checked case by case.

	o		Particle emissions: The particle emissions are calculated based on the average of minimum three samples. For heavy fuel oil a minimum sampling time per sample of 30 minutes is recommended. For light fuel oil 60 minutes is recommended, while for gas fired engines a minimum sampling time of 90 minutes is recommended.

Longer sampling times might be needed, if required by the measurement method or if variations in the measured concentrations are expected. Longer sampling times are also recommended if the verification of the Guarantee requires accurate determination of very low concentrations.

The analysers typically report the emissions at actual conditions, such as for example ppm-v, at actual oxygen, wet. The measurement results have to be corrected to the same reference conditions (e.g. mg/Nm³. at 15 % O₂, dry) where the Stack Emission Guarantees are specified before evaluation of compliance with the Guarantees can be made. These calculations are performed by the independent consultant. The measurement report shall include both the corrected emission and the uncorrected emission data including help variables such as oxygen and humidity used for correcting to reference conditions. At request the consultant will prepare a preliminary report / standard recording form at site.

Other data which is to be recorded during emission tests include fuel data, ambient conditions (temperature, humidity) and engine data (at minimum engine load during the test). Taking of the fuel samples is usually coordinated with other performance tests. This data is shall be appended to the measurement report

3 Measurement Methods

The measurement methods and standards to be used are specified in combination with the stack emission guarantees. In this chapter basic measurement principles for most typical emission species are provided, as well as additional requirements that need to be followed in order for the stack emission guarantees to be valid and in order to have reliable measurement results. In case the measurement methods have not been specified in the stack emission guarantees, verification of the emission guarantees shall be performed according to the below recommendations.

Doc. Classification: Confidential


		DocID: DAAB195899		Revision: b.10		3(4)

The chemiluminescence analyser as described in the US EPA Method 7E and in other principally similar methods and standards will be used for nitrogen oxides (NO_x) analyses.

Calculation method as described for example in the ISO CD 8178-1: 1996 (E) standard (chapter 7.4.3.7) will be used to determine of SO₂ emissions. Determination of SO₂ emissions from fuel composition using a combustion balance will provide more accurate data compared to direct measurements. Fuel samples (minimum 1 litre each) will be taken during the test period and analysed in an accredited laboratory. Direct measurements are only recommended in cases where the SO₂ emissions are controlled using “secondary technology”.

Note that the SO₂ emissions from gaseous fuels are typically so low that determination of SO₂ emissions is not relevant. If determination is required, e.g. for legislative reasons, it is recommended to use a theoretical calculation based on a combustion balance also for gas engines.

The concentration of particulate matter (as dry dust) will be determined by a manual gravimetric method as described in the ISO 9096:2003(E) and in other principally similar standards. Many measurement methods and standards for particles provide procedures for both in-stack and out-stack sampling of particles. It is important to note that the two variations will provide different results as a result of the temperature dependence of particle emissions. Therefore, the emissions guarantees are valid only for the procedure specified in the Stack Emission Guarantees. Unless specified differently in the Guarantees, the following apply:

	o		If the flue gas temperature exceeds 160 °C in the point of PM sampling, an in-stack filter shall be used for collecting the PM samples.

	o		In case the flue gas temperature is equal to or less than 160 °C at the point of PM sampling, a heated out-stack filter shall be applied.

For PM measurement of the flue gas from engines burning sulphur containing fuels, the filter material to be used for sampling must be inert enough. Quartz fibre is a recommended filter material. Glass fibre filters must not be used.

The particle emissions in the exhaust gas after a gas engine are generally on a low level and are therefore typically not verified.

Note that the weighing of the PM samples typically will take place at a laboratory outside the job site and hence no PM measurement results are available at the completion of the Stack Emission Test.

4 Calibration

Analyzers for measuring gaseous components shall be calibrated to ensure accurate measurements. The calibration of the analysers shall be carried out using certified calibration gas.

As a minimum, one span gas (high-range gas) having a concentration near the measured concentration shall be used for each component. The zero gas can be purified ambient air or N₂. The impurity concentration shall be less than 0.25 % of the span in the zero gas. The O₂ analyser

Doc. Classification: Confidential


		DocID: DAAB195899		Revision: b.10		4(4)

will be calibrated using a calibration gas, such as N₂ and ambient air. N₂ is needed in setting the zero point and ambient air for setting the span.

The analysers for the gaseous components will be calibrated daily at the Job Site. Analysers shall be calibrated prior to commencing the measurements as well as after the measurements. The setting of the zero and span points shall be performed according to the emission measurement methods and standards. Unless otherwise specified by the measurement method or standards, the following recommendations shall apply:

	o		Instrument calibration drift of 2-5 % of calibration gas concentration: the results shall be corrected using the determined drift figures.

	o		If instrument calibration drift of more than 5 % of calibration gas concentration is determined, the reason for the drift shall be determined and the tests shall be re-performed.

Pitot tubes, thermal elements and manometers shall be calibrated before the shipment to the Job Site. The traceable calibration certificates for this equipment as well as for the calibration gases will be made available. The analytical balance, which is used in the laboratory for weighing the PM samples, shall be traceably calibrated. The relevant calibration certificates and calibration gas certificates shall be appended to the measurement report.

5 Uncertainty Assessment and Acceptance

Emission measurements involve significant measurement uncertainties. Therefore, the uncertainties need to be quantified and accounted for in a predefined way.

Uncertainties originate from the whole measurement chain including sampling point, sampling line, analyser tolerance, fuel heating value, density and fuel flow measurement. The document published by the WECC (Western European Calibration Co-operation) DOC.19 — 1990 “Guidelines for the Expression of the Uncertainty of Measurements in Calibration” gives detailed guidelines on calculating and assessing uncertainties. Measurement uncertainties shall be evaluated and reported by the measurement consultant carrying out the measurements.

Assessment of the fulfilment of Flue Gas Emission Guarantee shall be made according to Section 6.2 of the VDI 2048 document “Uncertainties of measurement during acceptance tests on energy-conversion and power plants”.

PROCEDURES FOR QUALITY ASSURANCE AND H&SE OF WÄRTSILÄ POWER PLANT SUPPLY

1. MANAGEMENT SYSTEM OF WÄRTSILÄ

Wärtsilä Finland Oy follows a Quality management system that has been assessed to conform to the ISO 9001 standard and an Environmental management system that has been assessed to conform to the ISO 14001 standard. Wärtsilä have also implement Occupational Health and Safety management system OHSAS 18001, this will be certified during August 2009 . The management system is assessed continuously by an external body, re-auditing the system twice a year.

2. WÄRTSILÄ POLICY FOR QUALITY, HEALTH & SAFETY AND THE ENVIRONMENT

Policy statement:

Our Power solutions and services meet or exceed the customers’ and other stakeholders’ expectations being:

- Reliable and safe

- Efficient and environmentally sound

- Compliant with the applicable legal requirements and regulations.

We continually improve our performance and reduce adverse environmental impact, through objectives set by management, to satisfy our customers and other stakeholders. Our business premises provide a safe and healthy working environment for our employees and partners.

Our skilled organization acts as a responsible global citizen.

2. QUALITY ASSURANCE OF ENGINES

In accordance with ISO 9001 the Quality assurance is implemented into working methods ensuring that the engine will reach the specified Quality demands in every aspect.

As an instrument for the Quality follow-up, an engine specific Quality plan is made. This plan includes Quality demands and inspections to be made at different stages during the manufacturing process. This is the standard procedure used by Wärtsilä in order to ensure the Quality level of the products.

3. INSPECTION OF ENGINE MAIN COMPONENTS

The Quality assurance program includes factory certificate practise for main parts of Wärtsilä engines. During the performance test these measurement reports, material certificates and pressure test reports can be made available for customer’s review. All main components have their own serial numbers, and thus the corresponding certificate and measurement report can be traced.

4. TEST RUN OF ENGINES

The Quality assurance program includes all preparations before test run; running-in, test run procedures and checking/ calibration of the loading device. The delivery test run will be performed according to the standard testing procedure if not otherwise stated in the contract.

5. QUALIFIED SUPPLIERS OF WÄRTSILÄ

Wärtsilä utilizes well Qualified vendors as engine part and auxiliary equipment manufacturers. Supply contracts are made with most of the suppliers. Because of long term supplier co-operation, well proven equipment is delivered.

Most of the suppliers delivering equipment and components to Wärtsilä Power Plants and Wärtsilä Manufacturing have Quality management systems in accordance with the standard ISO 9001.

6. SUPPLIER ASSESSMENT PROCEDURES FOR WÄRTSILÄ POWER PLANTS

Quality integration file

The Quality integration file is the main tool used for guiding suppliers into the Wärtsilä Power Plants way of working.

Feedback about findings are forwarded to the supplier using the following tools:

Claim vs. supplier

To systematically improve the Quality of the products and services of Wärtsilä Power Plants suppliers, whenever motivated a claim vs. supplier is issued.

A claim vs. supplier can be issued based upon a customer complaint, on the initiative of the project team, or as a result of a delivery inspection, made by Wärtsilä representative, at the suppliers’ workshop.

Delivery inspection

When the product is ready for delivery a Wärtsilä representative will be given an opportunity to check the conformance with the order specification at the supplier’s work shop.

Supplier audit

Based on the result of the supplier evaluation, claims, inspection result statistics, etc, audits of suppliers of main equipment are carried out.

The supplier audits are prepared in advance. As a result supplier audit reports are made which are distributed to the supplier and to concerned parties within Wärtsilä.

Supplier evaluation

The information from the mentioned tools is used when evaluating the suppliers’ performance.

Page 2/8

The information from the mentioned tools is used when evaluating the suppliers’ performance.

6. QUALITY ASSURANCE OF AUXILIARY UNITS

For units and equipment manufactured at the suppliers workshop, Wärtsilä Quality instructions and guidelines are implemented. The documentation is stating the Quality level for the units in question. For main auxiliary units a specific Quality plan / ITP is made. This plan includes the Quality requirements to be met and inspections to be made.

7. TEST RUN OF AUXILIARY UNITS

Wärtsilä and the supplier develop unit specific delivery factory acceptance test and/or dispatch inspection procedures. During the manufacturing random checks can be made by Wärtsilä. These checks are performed based on the purchase orders, drawings and specifications.

Before the delivery, the supplier always performs the factory acceptance tests and/or dispatch inspections, either on his own or together with a Wärtsilä representative.

This test run results in a factory test report, an inspection report or a certificate. These documents will be delivered to the customer as a part of the final documentation for the plant.

8. FACTORY ACCEPTANCE TESTS

For serial manufactured equipment Wärtsilä accept vendors authorized factory acceptance test procedures. Where the contract between Wärtsilä and the customer has specific requirements for factory acceptance tests, these shall be agreed before the test program is finalized.

9. POWER PLANT ERECTION AND COMMISSIONING

The installation of the equipment is made in accordance with the drawings and installation instructions given for the specific project in the installation file. Comprehensive commissioning tests are carried out when the installation is completed. Prior to these tests, all pipe systems, auxiliary units, electrical systems, equipment and EG-sets are adjusted and calibrated for proper function. The commissioning is made to ensure the functionality and performance of each individual equipment and the whole plant. These tests result in a commissioning file and the issuing of a handing over certificate. Handing over documents are prepared as specified in the contract and signed by both the client and Wärtsilä. Any open items will be listed in a punch list and a schedule for the correction is made.

10. QUALITY ASSURANCE AND CONTROL BEFORE START UP

The Quality of the work at site is followed up by the site manager and his supervisors. Quality instructions, installation instructions and contract requirements are followed at site. Before starting the installation work necessary documents are given to the client and to the subcontractors at site. All equipment will be tested according to Wärtsilä standard procedures.

11. QUALITY ASSURANCE AND CONTROL AFTER HANDING OVER

During the warranty period a person from the Wärtsilä Customer Assitance Centre is named as a contact person for the customer. When the warranty period has expired, a contact person from the Wärtsilä network company is named to serve the customer.

The contact person is regularly in touch with the customer making visits to the power plant and discussing with the customer about preventive actions to maintain the Quality of the equipment. If there occur any problems with the Quality of the equipment, the contact person ensures that the supplier is involved to rectify the problem (according to Wärtsilä’s claim handling procedures). The contact person encourages the customer by support to maintain the Quality of the equipment by himself.
