Acta Marine has signed a contract for the construction of two methanol /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 that was exclusively designed for and in cooperation with Acta Marine.
The CSOVs measure 89 metres in length, 19 metres in width and accommodate up to 135 people in 85 cabins. They will be equipped with an SMST provided Motion Compensated Gangway system, mounted on an integrated tower with height adjustment and a /cargo lift. Additionally, the vessel features an SMST 3D-motion compensated crane with six tonne lifting capacity. Cargo area is 500 square metres indoors, and 500 square metres outdoors.
The vessels provide for walk-to-work transfer of personnel and cargo, efficient and safe in significant wave-heights up to 3.0 metres. The design aims for in-field agility, high operability and workability, safe transfer of people and cargo, optimized on-board logistics, high productivity and high comfort for charterers’ crews.
Acta Marine’s new CSOVs will be able to 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 Q2 and Q3 2024.
“Acta Marine is growing along with the offshore wind construction market by ordering these two vessels while remaining one of the leaders in this field. The dedicated SX-216 design with a TWIN-X stern, an integrated walk-to-work gangway system and 3D crane and its hotel style accommodation represents a next step in responding to the market needs,” says Rob Boer, Managing Director at Acta Marine. A first in offshore wind this vessel will be capable of operating on dual fuel methanol and /HVO enabling a strong carbon footprint reduction in the near future in combination with a battery power system.”
Acta Marine sees methanol as one of the most viable alternatives to minimize her 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. This will allow early application of significant CO2 reduction measures now, while still allowing net-zero operations over the life of the ship”, states Simon Anink, General Manager at Acta Marine.
Since its pioneering introduction of walk-to-work vessel Acta Orion late 2015 followed by Acta Auriga and Acta Centaurus, Acta Marine has transferred over 150,000 workers to and from wind turbines and offshore structures in sometimes challenging weather conditions.
