Penta-Ocean Construction has ordered a cable-laying vessel (CLV) from the PaxOcean Group that will cost an estimated $243 million and be one the largest, most advanced such ships.

A press releases said that Penta-Ocean Construction, a major Japanese construction firm, specializes in marine works and land reclamation. The company said the order reflects its plan to expand beyond offshore wind turbine construction into power cable installation, targeting future offshore wind power projects in Japan’s exclusive economic zone and other regions.

The CLV will be self-propelled and mounted with two 5,000-metric to cable carousels that can provide “safe and efficient cable laying in the open sea” even in severe ocean conditions. It will include a trencher for burying cables and  work class remotely operated vehicle (ROV). The vessel is scheduled to be delivered in February 2028.

The 14,000-dwt cable layer was designed by Norwegian firm Salt Ship Design. PaxOcean Group, based in Singapore, will build the ship at its Batam yard. “The cable layer is capable of laying and burying not only cables for bottom-fixed offshore wind turbines but also for floating-type offshore wind turbines, as well as submarine direct current power transmission cables,” Penta-Ocean said.

Per Penta-Ocean, the cable layer will be 50/50 owned by a company subsidiary and Fuyo General Lease Co, while the trencher and work class ROV will be 65/35 owned by a company subsidiary and Kojimagumi Co. Japanese ocean dredger company Kojimagumi will handle the vessel’s operational management.
