Acta Marine has taken delivery of Acta Pegasus, its fourth walk-to-work unit and a DP2 construction service operation vessel (CSOV). The vessel is the first in a four-ship newbuild programme and is set to work from Montoir-de-Bretagne under the French flag, supporting offshore wind projects in France.
The newbuild is part of a quartet being built for Acta Marine at Tersan Shipyard in Turkey. Acta Pegasus is arranged for up to 135 persons in 88 cabins and is fitted with offshore access and lifting systems, including a 3D motion-compensated gangway and a 3D-compensated crane.
The company said the vessel is prepared for methanol use and features dual-fuel capability aimed at lower-emission operations. CEO Rob Boer said the vessel is being mobilised and final preparations are underway ahead of its first assignment.
On the wider series, Acta Marine said sister vessel Acta Hercules is under construction and is due to enter service in the first quarter of 2026. Acta Gemini and Acta Aquarius are scheduled to follow in the second quarter of 2026.
Acta Pegasus is built on Ulstein’s twin X-STERN hull design, which is described as reducing pitching and improving operability in-field, with high DP capability for demanding conditions. The vessel’s dual-fuel engines can run on marine gas oil or a marine gas oil–methanol blend and are supported by substantial battery capacity. For lifting work, the SMST 3D motion-compensated crane is rated at 6 t at full compensation. The gangway supports walk-to-work transfers in wave heights up to 3.0 m and includes an integrated elevator for personnel and cargo movement. Amenities listed include a restaurant, multifunctional lounges, sauna, gym, and smart Wi-Fi connectivity.
