Construction of two Acta Marine CSOVs begins in Tersan

The building of two dual-fuelled construction service operating vessels (CSOV) by Turkey’s Tersan Shipyard for Acta Marine has been marked by a traditional steel-cutting ceremony. The 89m-long vessels will be built to a SX216 design developed by Ulstein Design & Solutions AS and are due for delivery in the second quarter of next year.

The two ships, claimed to be the first to be contracted with Ulstein’s distinctive Twin X-Stern, will be capable of operating on methanol MDO/HVO (hydrotreated vegetable oil) supported by an energy storage system. They will have motion-compensated cranes and gangways from SMST that will enable the safe transfer of engineering personnel in significant wave heights of up to three metres. Accommodation for up to 135 persons will be available on board.

The Twin X-Sterns mean that the vessels will have two sterns, main propeller units at each end, and a symmetrical hull design which reduces energy consumption and motions, thereby increasing uptime and personnel comfort. The hull configuration also improves manoeuvrability and position-keeping.
