Tersan Shipyard has celebrated the steel cutting of NB1121, the second Offshore Wind Farm Support Vessel of Acta Marine projects. Tersan Shipyard is building 2 pcs DP2 Construction Service Operation Vessels powered with Methanol and MDO/HVO for Acta Marine Netherlands.

Designed by Ulstein Design & Solutions AS with the cooperation of Acta Marine, the two vessels are planned to serve in the offshore wind market. Including TWIN-X stern, an integrated walk-to-work gangway system, 3D crane and the hotel styled accommodation areas, the vessels will be targeting the market expectations and needs.

89 meters long and 19 meters wide vessels will be able to accommodate up to 135 people in 85 cabins. The CSOVs will be equipped with Motion Compensated Gangway systems supplied from SMST, mounted on the integrated towers with height adjustment and a personnel/cargo lift. 

Addition to the advanced gangway system, they feature a 3D-motion compensated crane with 6 tons of lifting capacity again supplied by SMST and 500 m2 indoor and 500 m2 outdoor cargo areas. The two vessels are aiming to provide a short, efficient and safe transfer of personnel and cargo even in the harsh weather conditions where the level of waves reaches up to 3.00 meters.

The vessels will provide high agility, operability and workability during the transfer of people and cargo. Optimized on-board logistics, high productivity and high comfort for the crew add great value to the vessels and dual fuel methanol driven propulsion will provide significant CO2 reduction measures. The first two vessels are scheduled for delivery Q2 and Q3 2024.
