Oil product trading, marine measuring instruments
Thread Content
In the transfer of LNG shipping trades, inspections are carried out on shipboard instruments (such as the CTMS system, which includes corrections for the ship’s list and trim). Is Arikawa Tomo familiar with this type of instrument? Or are there any relevant materials? I would be extremely grateful if you could share it!
What other instruments are available for trade metering besides high-precision mass flow meters? I want to know! What’s the difference between marine and regular ones?
Most bulk oil trade is measured using marine instruments, rather than just flow meters. The main step is to check the tank capacity before unloading, and the tank capacity after unloading, and then subtracting the two values to determine the volume of the oil. Then the mass is calculated based on the density. For LNG, it is also necessary to calculate the calorific value. Because foreigners always use energy units for transactions. Therefore, it is important to understand these measuring instruments on board.
Marine instruments seem to have to be certified by a classification society

Thank you for sharing. China is currently developing and manufacturing LNG inland transport ships, which could be promoted
Yes, it seems there’s nothing like this in China. Trade ships and ocean-going vessels have their measuring instruments certified by an agency abroad.
