Sample Solution

unker options for LNG
For every bunkering operation the hoses and pipeline to the tank are required to be cooled down to -162 C°. The lng will have a temperature of -169 C° to keep their liquid phase while bunkering.
The tank is also required to be cooled down when the temperature is above -162 C°. For all the bunker options there is still no approval to carry out cargo ops and bunker LNG at the same time.
Bunkering by terminal
This bunkering is in almost the same way as diesel bunkering. The bunkering of diesel is nowadays still possible at the terminal after the cargo is carried out. The amount of terminals who allows the fuel bunkering will become less because of the bunker spill risk. It takes a lot of time when there is a fuel spill, everything needs to be cleaned and checked before the next vessel can load or discharge cargo. There will be a separated fuel bunker terminal, the vessel needs to sail to the terminal. The LNG terminal is nowadays in the same way as the separated diesel terminal in the future.
Bunkering by truck
Bunkering by truck is most of the times possible. The ship requires to have their own manifold for reloading the fuel tanks. Every discharge of one truck takes 2 hours, with the manifold you can discharge more trucks at the same time, it depends on your manifold. From the information of Shell the maximum amount of trucks that can do simultaneous bunkering is 12 trucks.
Tank swap
Put a fuel tank unit at the mounting plate on the ship. Connect the fuel pipes and sail, when the tank is empty disconnect the fuel pipes and lift the fuel tank of the ship. And just load a new fuel tank unit, reconnect the fuel pipes and sail again.
There is still no approval for this option, because this is only a concept.
Ship to ship bunkering
It’s in the same way as HFO and MGO are bunkered by ship, but then with LNG.
