New Acta CSOV enters service

The DP2 construction service operation vessel (CSOV) is the first of four sister newbuilds being delivered from Tersan Shipyard in Turkey. With accommodation for up to 135 people and advanced motion-compensated access systems, the vessel is designed for sustained offshore operations in challenging conditions.

Rob Boer, chief executive of Acta Marine, said the vessel reflects a shift in expectations for offshore support tonnage. “The arrival of Acta Pegasus marks a new standard for sustainable Walk-to-Work vessels,” he said. “We are currently mobilising the vessel and making final preparations to deploy her to her first project.”

Acta Pegasus will sail under the French flag and be deployed from Montoir-de-Bretagne, supporting offshore wind projects along the French coast. The move underlines Acta Marine’s focus on positioning assets close to expanding renewable energy markets rather than relying on redeployment from further afield.

The vessel is based on Ulstein’s twin X-STERN hull design, aimed at reducing pitching and improving operability on station. Offshore access is provided by a 3D motion-compensated gangway capable of operating in wave heights of up to three metres, alongside a 3D-compensated crane with a six-tonne lifting capacity at full compensation.

In line with tightening emissions expectations from offshore wind developers, Acta Pegasus has been built methanol-ready. Dual-fuel engines can operate on marine gas oil or a methanol blend, supported by a substantial battery energy storage system.

Sister vessel Acta Hercules is scheduled to enter service in the first quarter of 2026, followed later in the year by Acta Gemini and Acta Aquarius.
