Determination of Gross Heating Value Clause Samples

Determination of Gross Heating Value. The GHV shall be determined by means, which are approved under applicable regulations as described in AC 3.6, such means currently being on-line gas chromatographs using ISO 6974 and calculated using ISO 6976-1995 at combustion reference temperature of 25°C and normal volumetric conditions, as specified in AC 3.6. The accuracy of the measurement equipment provided or caused to be provided by the RMFO at the Redelivery Point shall be verified and calibrated by the RMFO at intervals as set forth in AC 3.6. Shipper shall have the right to attend such verifications. Except in case of Emergency, the RMFO shall give notice to Terminal Operator and Terminal Operator to Shipper, ten (10) Working Days before the start of any such test. All tests of such measurement equipment shall be made at the RMFO's expense. If the aggregate error in any of the individual metering lines is found to exceed the technical tolerance of the applicable measurement equipment in such metering line being one decimal zero (1.0) per cent then any previous recordings of such measurement equipment shall be corrected to zero (0) error for any period which is known definitely, or agreed upon, but in case the period is not known or agreed upon, such corrections shall be for a period extending over one-half of the time elapsed since the date of the last test, or another correction period specified in AC 3.6. Fuel Gas calculations pursuant to GC 4.1 and GC 5.3 and energy balance calculations pursuant to AC 3.1.6.3, over such period shall be corrected accordingly. Following each test, the measurement equipment shall be adjusted if found to be necessary to record accurately and said measurement equipment shall be secured against unauthorised manipulations by personnel of Shipper, Terminal Operator and the RMFO. If, for any reason, meters are faulty or out of service, so that the Quantity of the Natural Gas redelivered at the Redelivery Point cannot be ascertained or computed from the reading thereof, the Natural Gas made available during the period during which such meters are out of service or faulty shall be determined upon the basis of the best data available, using only the first feasible method of those listed hereunder in the same order:

Determination of Gross Heating Value. The GHV shall be determined by means, which are approved under applicable regulations as described in AC 3.6, such means currently being on-line gas chromatographs using ISO 6974 and calculated using ISO 6976-1995 at combustion reference temperature of 25°C and normal volumetric conditions, as specified in AC 3.6.

Determination of Gross Heating Value. The GHV of the Fuel Gas shall be determined by use of on-line gas chromatographs, which are operated in accordance with applicable standards and regulations, which are as of the Effective Date, ISO 6974 for molar gas composition, and ISO 6976 for GHV computation at combustion reference temperature of 25°C and normal volumetric conditions.

Determination of Gross Heating Value. The gross heating value of the gas delivered hereunder shall be determined by calculating the BTU from an on-line chromatograph or a gas analysis of a spot or continuous gas sample. Spot samples shall be taken at least quarterly, and a continuous sample shall be taken monthly. Such sample shall be taken at a suitable point on the facilities to be representative of the gas being metered.

Determination of Gross Heating Value. (a) GPA 2261 and 2145. The heating value of the Gas delivered by FLNG at the Delivery Point shall be determined by gas chromatograph. The composition of the Gas shall be continuously measured by on-line chromatographs. The Gross Heating Value of the Gas shall be calculated using results from the on-line chromatograph. The chromatographs will analyze all hydrocarbon components, up to and including at least the Nonanes+ group, and inerts having a concentration of greater than 0.002 mol percent. The determination of Gas composition shall be in accordance with the GPA Standard 2261 - Analysis for Natural Gas and Similar Gaseous Mixtures by Gas Chromatography. All physical properties used in quality and quantity calculations shall be based on these compositional analyses and the component values published in GPA 2145, or the latest revision thereof. Water vapor content shall be included in the component analyses. The sample analysis cycle time shall be less than 6 minutes. The maximum response time from sample probe to analyzer shall be four minutes. In the event of failure of the on-line Gas chromatograph, chromatograph analysis of samples collected proportional to the flow through the meters shall be used. Auto-calibration of the Gas chromatograph shall be conducted on a weekly basis or as otherwise mutually agreed by the Parties.
