1.3.3 Operation in fuel sharing mode
The fuel sharing mode is initiated only by the operation and can be used for
reaching a balance between a carrier’s LNG boil-off and the desired ship speed.
This can be done by adjusting the ratio of gas to liquid fuel.
Figure 1-6 Fuel sharing mode — available operating window
The fuel sharing mode is available in a defined working window (see Figure 1-6).
The minimum amount of liquid fuel is equivalent to 5% of energy input. During
fuel sharing mode the engine is also Tier II compliant.
NOTE
Fuel sharing mode is an available engine option but must be contracted
(with additional cost).
