Acta Marine has announced the delivery of Acta Gemini, its latest Walk-to-Work (W2W) DP2 Construction Service Operation Vessel (CSOV), built at Tersan Shipyard, Yalova Turkey.
As the third vessel in a series of four newbuilds, Acta Gemini represents a further step in Acta Marine’s continued investment in a modern and future-ready fleet.
The vessel is purpose-built to support offshore wind construction and maintenance activities, combining strong operational performance with a clear focus on safety, efficiency, and crew comfort.
Following the mobilisation, Acta Gemini will commence a long-term charter in support of the Sofia Offshore Wind Farm at Doggerbank, UK. Operating from Grimsby, the vessel will provide offshore accommodation and walk-to-work services to support the operations and maintenance activities of the wind farm on behalf of RWE.
“The delivery of Acta Gemini, combined with a long-term charter commitment from RWE, underlines both the strength of our fleet and the confidence of our clients in our organisation and services. With this vessel, we continue to build on the foundation laid with Acta Pegasus and Hercules and further strengthen our position in the offshore wind market,” says Rob Boer, CEO of Acta Marine.
Acta Gemini can accommodate up to 88 personnel and is equipped with an advanced offshore access system, a helideck and daughter crafts, enabling flexible, safe and reliable transfer of technicians to offshore installations. In line with Acta Marine’s sustainability ambitions, the vessel is equipped with methanol dual-fuel main engines and methanol-ready, supporting the company’s pathway towards lower-emission operations as regulatory and market conditions evolve.
With Acta Pegasus and Acta Hercules already delivered and Acta Gemini now entering service, the remaining sister vessel Acta Aquarius is scheduled to follow later in 2026. Together, this newbuild series of four vessels forms a key pillar of Acta Marine’s long-term strategy to expand and modernise its fleet in line with the evolving offshore energy market.
