Process details
Loading and fueling in the oil & gas industry
Monitoring of loading and fuelling
A recent development is ‘Small Scale LNG’, which involves the supply of smaller quantities of LNG delivered via a road tanker or a small ship, for distribution to special LNG fuel stations or loading facilities. The LNG is then sold as a fuel for trucks and for ships, which can reduce emissions in line with modern environmental policies. Also LNG bunkering ships are under development, which would refuel larger ships while they are in port loading or unloading their cargo.

Applications
Custody transfer flow measurement for (un)loading of LNG
- Equipping a dispensing system for cryogenic fuels with a Coriolis mass flowmeter
- Continuous measurement and indication of 2-phase-flow in the event of boil-off-gas (BOG)
- Improved control of loading procedure, cooling time and product quality
