Acta Marine has taken delivery of the walk-to-work (W2W) construction service operation vessel (CSOV) Acta Aquarius, the company announced on Friday, November 13.
Acta Aquarius is the fourth and final unit in a series of DP2 CSOVs built to an Ulstein design. She follows Acta Pegasus, Acta Hercules and Acta Gemini.
When the third and fourth vessels were ordered in 2023, Acta Marine said it had signed a 12-year contract with RWE for the pair. The contract covers the Triton Knoll and Sofia offshore wind farms from the Port of Grimsby. Acta Gemini began her RWE charter at Sofia in August.
The vessel is certified for methanol dual-fuel operation. Her engines can run on marine gas oil (MGO) or a blend of MGO and methanol, and they are supported by a battery energy storage system.
Acta Aquarius has a length overall of 89.6 metres, a moulded breadth of 19.2 metres, a moulded depth of 7.6 metres and a design draught of five metres. Her double-ended hull carries two main propeller units at each end.
The vessel has a motion-compensated gangway rated for transfers in wave heights of up to three metres, as well as a 3D motion-compensated knuckle-boom crane. She is accompanied by the daughter craft Acta Situla, which was delivered in June.
