Fuel changeover

The main engine and auxiliary engines are designed to burn HFO most of the time. However, operational circumstances may necessitate the changeover HFO to DO, for example if:
o  and it is anticipated that the ship's auxiliary or main engine will be shut down for a long time for the following reasons:
✔  the ship is in port or at anchor (ECA).
✔  repairs are required for fuel systems or related systems.

o  and planned work in the sulfur emission control area when not available LSFO.

Fuel switching can be performed at any time, regardless of whether the engine is running or turned off at that time. Careful adherence to fuel change procedures is essential to prevent high pressure fuel equipment from structuring or deteriorating fuel combustion in the cylinders and contaminating the gas ducts.
