Kongsberg Maritime has been selected to provide a comprehensive, fully integrated technology and equipment package for a next-generation ultra-large cable lay vessel being built for LS Marine Solution at Tersan Shipyard in Türkiye, dated 25 February 2026.
The newbuild is being developed to serve subsea high-voltage direct current (HVDC) cable and optical cable installation requirements. It is specified at 148.4 m in length and 31 m in beam, with a 13,000 tonnes cable carrying capacity and total displacement of 18,800 tonnes.
Kongsberg Maritime’s delivery scope includes K-Pos dynamic positioning systems, integrated control and navigation systems, a battery-hybrid DC electrical system, and the full main propulsion and thruster package.
Nazım Yasar, Project Manager at Tersan Shipyard, said the project relies on close collaboration and highlighted the combination of Kongsberg Maritime’s integrated systems and LS Marine Solution’s project ambition. Leszek Kopec, Senior Sales Manager at Kongsberg Maritime, said the parties have focused on reducing CAPEX, OPEX, space, weight and emissions while maintaining operability and efficiency. Kongsberg Maritime added that this is its fifth fully integrated system award for cable lay vessels within the past year.
Emre Kopuz, Senior Sales Manager – Mediterranean & Middle East at Kongsberg Maritime, said the contract builds on the company’s long-standing cooperation with Tersan Shipyard and supports LS Marine Solution in delivering an advanced asset for sustainable energy infrastructure.
The battery-hybrid DC power and propulsion arrangement is intended to reduce the number of engines needed during operations. A high-capacity shore connection, supported by the battery system and the Energy Control System, is intended to enable zero-emission operation during port stays and cable loading. Positioning accuracy and operational performance are also supported through K-Pos DP systems and permanent magnet motors fitted on all azimuth thrusters.
The design also allows mobilisation of Remote Cable Pull-In systems for floating wind farms, enabling pull-in and hang-off operations for dynamic cables without personnel transfer or crane-based equipment handling.
Construction at Tersan Shipyard is expected to take around three years, with the vessel planned to enter service in 2028.
