GENERAL TERMS AND CONDITIONS

(Continued)

 

(f) Samples of the LNG shall be taken with a frequency adequate to assure a representative

analysis of the LNG being unloaded, at a suitable point near the Receipt Point. The

sampling device shall be such as to permit the total and continuous vaporization of a

quantity of LNG sufficient for the taking of a gaseous sample representative for the

LNG then being unloaded. Such samples shall be analyzed by means of a suitable gas

chromatograph. An analysis or the average of such analyses shall determine the

molecular composition of the LNG. A calibration of the chromatograph utilized shall be

performed before the analysis of the samples taken from each unloading.

Representatives of Customer and Southern LNG shall have the right to be present at

such calibrations, but the absence of a representative shall not prohibit any

calibration. Such calibration shall be effected with the aid of a gaseous mixture

having a known composition closely similar to the vaporized LNG being measured.

 

(g) The Gross Heating Value (GHV) of LNG shall be calculated on the basis of its molecular

weights and the Thermies per kilogram of each of its components. The values of

physical constants to be used for such calculations shall conform to those contained

in the most current publications of the National Bureau of Standards of the United

States, or a successor agency.

 

(h) The quantity of Dth unloaded from Customer's vessel(s) shall be calculated on the

basis of the following formula:

 

Q = V x M x Pc

252

 

where:

 

Q = the number of Dth unloaded

 

V = the volume of LNG unloaded, in m3, as determined in accordance with GT&C §

4.1(b)

 

M = the density of the LNG in kg/m3 calculated in accordance with GT&C §

4.1(d)

 

Pc = the GHV of LNG per unit of mass, in Thermies/kg calculated in accordance

with GT&C § 4.1(g)
