Figure 1-11 Fuel sharing mode — energy amount of different ratios of fuel
The liquid to gas fuel ratio can be selected by the Remote Control System (RCS).
The automatic control of the ratio of liquid fuel is based on the LNG carrier’s
tank pressure. The automatic control is also possible through the PCS. De-
pending on the liquid fuel’s sulphur content, the base number of the cylinder lu-
bricating oil might need to be changed as described in the section 4.4.5 Cylinder
lubricating oil system,  4-26. For this purpose, the main engine can be option-
ally equipped with an Integrated Cylinder lubricant Auto Transfer (iCAT) unit.
