Ship history
In 2022, Olympic ordered two newbuild Construction Support Operation Vessels from Ulstein Verft. The vessels are among the first TWIN X-STERN vessels and operate in the offshore energy market. Ulstein Power & Control’s hybrid power solution incorporates a battery system and diesel generators operating at variable speeds to ensure optimal fuel utilisation. The power system also includes a shore power connection for battery recharging and emission-free port operations.
The vessels are prepared for methanol fuel, paving the way for low-emission operations. Space is also reserved for extra battery capacity, allowing full electric operations once the necessary infrastructure becomes available.
The vessels accommodate 126 people in all daylight cabins.
The gangway system enables the efficient transfer of personnel and cargo up to 2 tonnes at variable landing heights; 15-30 m straight and level. This modular system also includes a lift and a tailor-made tower.
The open deck area of 440 sqm and warehouse area of 500 sqm ensure ample capacity.
