Designed by Ulstein Design & Solutions AS with the cooperation of Acta Marine, the two vessels are planned to serve in the offshore wind construction 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.

Tersan Shipyard Business Development and Marketing Director Sakir Erdogan says “We are very proud to be awarded by Acta Marine as the builder of these significant vessels who will be key players of the renewable market. We are very motivated start working with Acta Marine whom are one of best companies in this sector and known with their professional approach. We are confident that we will reach our common goal of building innovative ships that will serve for a sustainable future. As Tersan Shipyard, we really care our production and consumption strategies to be equivalent in terms of renewability. During the whole building process of the vessels, we are using % 100 renewable energy provided by both I-REC certificated wind farms and also provided by more than 8000 pcs of our own solar energy panels mounted on the roof tops of the shipyard’s workshops which means green vessels are being built by using green energy at Tersan Shipyard” 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.

“A first in offshore wind market, this vessel will be capable of operating on dual fuel methanol and MDO/HVO enabling a strong carbon footprint reduction in the near future in combination with a battery power system. Furthermore, we are very excited that we have been able to sign an agreement with Tersan Shipyard that is well known for its quality and professionalism.” says Rob Boer, Managing Director at Acta Marine.
