6/28

Dual-Fuel The Preferred Ship Solution

Redundancy, backup without interruptions in power or speed.

Able to operate on liquid fuel outside ECA-areas Simple system, no PTI/take me home or double gas system needed.

DP class fulfilled with single tank/gas supply system

Operational flexibility - Vessel re-routing possible, gas supply not alimitation

DF mechanical propulsion

The vessel is able to run constantly andcontinuously in gas mode

LNG bunkering every second week or less

Constant load cycles due to heavy sea state

sailing in Norwegian waters.

Engine performance has never been alimitation for vessel operations

Load variations between 37% and 83%

MCR in 8 seconds

Average load 65% MCR with 79% PropellerPitch

Highest wind speed encountered 25 m/s
