Turkey’s Tersan shipyard has cut the steel on a second dual-fuel vessel that will be powered by methanol and diesel or HVO.

NB1121 has been ordered by Dutch vessel provider Acta Marine, and will be powered by methanol and either diesel or HVO (hydrotreated vegetable oil).

Designed by Ulstein Design & Solutions AS with input from Acta Marine, the two 89m construction service operation vessels (CSOVs) will mainly serve the offshore wind market.

They are equipped with Ulstein’s TWIN-X stern and an integrated walk-to-work gangway system, 3D crane and usual hotel-style accommodation for up to 135 people.

“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,2 says Tersan. “Addition to the advanced gangway system, they feature a 3D-motion compensated crane with six tonnes 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 three metres.

“The vessels will provide high agility, operability and workability during the transfer of people and cargo. Optimised 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.”

Both vessels are to be delivered in the second and third quarters of 2024.
