The Tersan Shipyard in Türkiye has laid the keel for the cable-laying vessel (CLV) it is constructing for South Korean subsea cable installation company LS Marine Solution.

LS Marine Solution and the shipyard signed a contract for the construction of the vessel in June 2025, followed by the start of construction in July 2026.

“We have successfully celebrated the keel laying of the next‑generation cable laying vessel InterOcean (Hull No. NB1139) which we built for LS Marine Solution. This milestone ceremony marks the official transition of the project into the construction phase, while highlighting the strong partnership between the two companies and underlining the vessel’s innovative role within the industry,” Tersan Shipyard reported on August 31.

Representing an investment of approximately €221 million, the CLV will be 148.4 meters long and 31 meters wide, and will have a load capacity of 13,000 tons and a total displacement of 18,800 tons.
