Built by Tersan Shipyard, Acta Gemini expands Acta Marine’s modern offshore support fleet for renewable energy operations
Acta Marine has taken delivery of Acta Gemini, the latest addition to its growing fleet of Walk-to-Work (W2W) DP2 Construction Service Operation Vessels (CSOVs), further strengthening the company’s capability to support offshore wind construction and maintenance operations. Built by Tersan Shipyard in Yalova, Türkiye, Acta Gemini is the third vessel in a series of four newbuild CSOVs being developed for Acta Marine.
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. Acta Marine is proud to contribute to the long-term success of one of Europe’s largest offshore wind projects and looks forward to continue supporting RWE in the safe and efficient operation of the Sofia wind farm for many years to come. “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.
