Perfecting liquefied natural gas analysis techniques and methods
Following these procedures will improve measurement accuracy and reliability
The nature of liquefied natural gas (LNG) raises many
challenges when it comes to the measurement and reporting of
its composition for the purpose of ship loading and unloading.
LNGs extreme temperature, and the difficulty with keeping
it in liquid form, introduce unique sample-handling issues,
while the batch-handling operation makes reporting difficult.
At the same time, the accuracy and reliability of the LNG measurement
is uniquely critical since the loading and unloading operations
are highly time-sensitive with no second chances. Delays in
loading or unloading because of measurement issues are not
tolerable when the cost of keeping a ship in port is
considered. For example, one LNG operator had two measurement
systems fail right before the docking of a large tankera
problem that could have resulted in significant penalties had
the failures not been remedied heroically. Additionally,
disparities in the measurement are often not known until after
the unloading is complete at the destination and comparisons to
the load report are made.
