Common use of MMBtu Calculation of the Quantity of LNG Loaded Clause in Contracts

MMBtu Calculation of the Quantity of LNG Loaded. The number of MMBtu contained in the LNG loaded shall be calculated using the following formula: The derivation of the conversion factor 1/1055.12 in the formula in this Paragraph for the conversion of MJ into MMBtu is obtained from GPA-2145:1994 and IP-251:1976 as follows: (a) q(T,P) means the gross heating value (measured at temperature T and pressure P), contained in a given quantity of gas; (b) q(60°F, 14.696 psia) in MJ = 1/1.00006 x q(15°C, 1013.25 millibar) in MJ; (c) 1 MMBtu corresponds to 1055.06 MJ; (d) q(60°F, 14.696 psia) in MMBtu = 1/1055.06 x q(60°F, 14.696 psia) in MJ; and (e) Combining (b) and (d) above yields: q(60°F, 14.696 psia) in MMBtu = 1/1055.12 x q(15°C, 1013.25 millibar) in MJ. Hence the number of MJ derived shall be divided by 1055.12 to obtain the number of MMBtu for invoicing purposes. QBOG = the quantity of boil off gas in MJ consumed by the LNG tanker during loading, calculated as follows: QBOG = (V2 x 55.575) where: V2 = the quantity of natural gas consumed by the LNG tanker during loading (as calculated pursuant to the below formula), stated in kg and rounded to the nearest kg; and

MMBtu Calculation of the Quantity of LNG Loaded. The number of MMBtu contained in the LNG loaded shall be calculated using the following formula: Q = 1 x { (V x d x Hm) - ( V x 288.15 x P ) x 37.7 + QBOG } 1055.12 273.15 + Tv 1013.25 The derivation of the conversion factor 1/1055.12 in the formula in this Paragraph for the conversion of MJ into MMBtu is obtained from GPA-2145:1994 and IP-251:1976 as follows: (a) q(T,P) means the gross heating value (measured at temperature T and pressure P), contained in a given quantity of gas; (b) q(60°F, 14.696 psia) in MJ = 1/1.00006 x q(15°C, 1013.25 millibar) in MJ; (c) 1 MMBtu corresponds to 1055.06 MJ; (d) q(60°F, 14.696 psia) in MMBtu = 1/1055.06 x q(60°F, 14.696 psia) in MJ; and (e) Combining (b) and (d) above yields: q(60°F, 14.696 psia) in MMBtu = 1/1055.12 x q(15°C, 1013.25 millibar) in MJ. Hence the number of MJ derived shall be divided by 1055.12 to obtain the number of MMBtu for invoicing purposes. QBOG = the quantity of boil boil-off gas in MJ consumed by the LNG tanker Tanker during loading, calculated as follows: QBOG = (V2 x 55.575) where: V2 = the quantity of natural gas Gas consumed by the LNG tanker Tanker during loading (as calculated pursuant to the below formula), stated in kg and rounded to the nearest kg; and
