Acta Hercules is the second DP2 Walk-to Work Construction Service Operation Vessel in four-unit series delivered by Tersan Shipyard
Acta Marine has taken delivery of its latest Walk-to-Work (W2W) DP2 Construction Service Operation Vessel (CSOV), Acta Hercules, from Tersan Shipyard in Türkiye, marking the second unit in a four-vessel newbuild series.
The addition of Acta Hercules underscores the company’s ongoing commitment to fleet modernisation, as it continues to invest in assets tailored to the evolving demands of the offshore wind sector. Purpose-built for construction and maintenance support, the vessel is designed to deliver high levels of operational performance while prioritising safety, efficiency and onboard comfort.
Acta Hercules will enter into a five-year charter with Vestas, supporting the construction of offshore wind projects across Northwest Europe. The vessel’s first assignment will be on the Hollandse Kust West project in the Netherlands, marking the start of a long-term collaboration with one of the leading players in the global offshore wind industry. Acta Hercules will be managed by Acta Marine France, located in Montoir-de-Bretagne.
“The delivery of Acta Hercules, combined with a long-term charter commitment from Vestas, 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 further strengthen our position in the offshore wind market,” says Rob Boer, CEO of Acta Marine.
Built on Ulstein’s advanced twin X-STERN hull design, Acta Hercules can accommodate up to 135 personnel and is equipped with advanced offshore access systems, enabling 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 already delivered and Acta Hercules now entering service, the remaining sister vessels, Acta Gemini and Acta Aquarius, are scheduled to follow later in 2026. Together, this newbuild series 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.
