ROTTERDAM, The Netherlands — Acta Marine has signed a contract for the construction of two next-generation methanol MDO/HVO-powered DP2 construction service operating vessels (CSOVs) at Turkish shipyard Tersan with two optional vessels for delivery at a later stage.
The vessels are primarily aimed at the offshore wind construction market and carry the new SX-216 TWIN-X Stern design from Ulstein Design & Solutions AS that was exclusively designed for and in cooperation with Acta Marine.
The SX-216 design features a TWIN-X stern, an integrated walk-to-work gangway system, 3D crane and hotel-style accommodation
“A first in offshore wind, 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," said Rob Boer, managing director with Acta Marine.
This vessel was designed to provide in-field agility, high operability and workability, safe transfer of people and cargo, optimized onboard logistics, and high productivity and high comfort for charterers’ crews.
Acta Marine sees methanol as one of the most viable alternatives to minimize carbon footprint in the marine space and, more specifically, for offshore vessels.
“Dual fuel methanol driven propulsion trains score high in terms of technology readiness and are eligible for further enhancement to a single fuel methanol upgrade at a later stage," said Simon Anink, general manager with Acta Marine. "This will allow early application of significant CO2 reduction measures now, while still allowing net-zero operations over the life of the ship.".
The CSOV measures 89 m in length, 19 m in width and accommodates up to 135 people in 85 cabins. It will be equipped with an SMST provided motion-compensated gangway system, mounted on an integrated tower with height adjustment and a personnel/cargo lift. Additionally, the vessel features an SMST 3D-motion compensated crane with 6-t lifting capacity. The cargo area is 500 sq m indoors and 500 sq m outdoors. The vessel shall provide for walk-to-work transfer of personnel and cargo, efficient and safe in significant wave-heights (Hs) up to 3 m.
Acta Marine’s new CSOVs can take on assignments in commissioning and construction of offshore wind farm installation phase and perform maintenance tasks on completed wind farms. The first two vessels are scheduled for delivery in the second and third quarters of 2024.
