Kongsberg Maritime has been selected to deliver a fully integrated technology package for a next-generation ultra-large cable lay vessel being built for LS Marine Solution at Tersan Shipyard in Türkiye.

The vessel, announced on 25 February, will be among the world’s largest cable layers and is designed to support rising demand for subsea high-voltage direct current (HVDC) and optical cable installation. It will measure 148.4 metres in length and 31 metres in beam, with a cable carrying capacity of 13,000 tonnes and a total displacement of 18,800 tonnes.

Kongsberg Maritime’s scope includes K-Pos dynamic positioning (DP) 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, commented: “Building one of the world’s most advanced ultra-large cable lay vessels requires strong collaboration, and we are proud to embark on this journey together.”

Leszek Kopec, senior sales manager at Kongsberg Maritime, said: "Working closely with the owner, designer, and shipyard, we have focused on reducing CAPEX, OPEX, space, weight, and emissions, while ensuring the vessels’ operability and efficiency”.

“This project reflects Kongsberg Maritime’s consistent commitment to applying our in-house domain knowledge of cable lay operations to optimise marine systems and mission system integration,” Kopec added.

The battery hybrid DC power and propulsion system is designed to reduce the number of engines required during operations. A high-capacity shore connection, supported by the battery system and Kongsberg Maritime’s Energy Control System, will enable zero-emission operations during port stays and cable loading.

The configuration is intended to lower greenhouse gas emissions and align with global ESG standards, supporting HVDC grid expansion and offshore renewable energy development.

The vessel will also feature permanent magnet motors on all azimuth thrusters and enhanced positioning accuracy through the K-Pos DP systems. The design allows for the mobilisation of Kongsberg Maritime’s Remote Cable Pull-In systems for floating wind projects, enabling dynamic cable pull-in and hang-off operations without crane-based handling or personnel transfer.

Construction at Tersan Shipyard is expected to take approximately three years, with the vessel scheduled to enter service in 2028.
