Acta Pegasus, a High-Performance CSOV Designed for Demanding Offshore Operations
Acta Marine, a leading provider of Walk-to-Work (W2W) and offshore support vessel solutions for the Offshore Wind and oil & gas sector, announce the delivery of Acta Pegasus, its fourth W2W vessel and a cutting-edge DP2 Construction Service Operation Vessel (CSOV).
As the first of four newbuilds in this series, Acta Pegasus will sail under the French flag and operate from Montoir-de-Bretagne in support of offshore wind projects across France. Equipped with advanced offshore access systems and methanol-ready dual-fuel technology, the vessel establishes a new standard for sustainable and efficient offshore wind operations, underscoring Acta Marine’s commitment to a modern, future-ready fleet.
Acta Pegasus is one of four newbuild vessels that are currently under construction for Acta Marine at Tersan Shipyard in Turkey. The vessel can accommodate up to 135 guests and is equipped with offshore access and lifting systems, including a 3D motion-compensated SMST gangway and a 3D-compensated crane. In line with Acta Marine’s sustainability ambitions, Acta Pegasus is methanol-ready, supporting the transition toward lower-emission offshore operations.
As the first newbuild vessel in the series of four, Acta Pegasus will sail under the French flag, supporting offshore wind projects in France. Operating from Montoir-de-Bretagne, Acta Marine France will provide reliable and efficient offshore support services to its clients, contributing directly to the growth of renewable energy in the region.
“The arrival of Acta Pegasus marks a new standard of sustainable Walk-to-Work vessels, featuring environmentally friendly technologies such as green methanol dual fuel engines significantly reducing the CO2 emissions. We are now mobilizing the vessel and making final preparations to deploy the vessel to her first project” says Rob Boer, CEO of Acta Marine.
Sister vessel Acta Hercules is currently under construction and due to enter service during the first quarter of 2026, followed by new build vessels Acta Gemini and Acta Aquarius during the second quarter of 2026. The four newbuild vessels are part of the company’s continued investment in a modern, sustainable future-ready fleet.
Acta Pegasus is built based on Ulstein’s advanced twin X-STERN hull design, providing reduced pitching, enhanced in-field operability, high DP capability and optimal performance in challenging weather conditions. The vessel is equipped with dual-fuel engines capable of operating on marine gas oil or a blend of MGO and methanol in combination with substantial Battery Energy Storage capacity. To support safe and efficient offshore operations, Acta Pegasus features an SMST 3D motion-compensated crane with a lifting capacity of 6 tonne at full compensation. The SMST motion-compensated gangway enables reliable Walk-to-Work transfers in wave heights up to 3.0 metres and is equipped with an integrated elevator for seamless transfer of personnel and cargo.
Designed with crew wellbeing at its core, the vessel offers 88 high comfort cabins accommodating up to 135 persons, complemented by high-quality amenities including a modern restaurant, multifunctional lounges, sauna, gym and smart Wi-Fi connectivity throughout.
