Kongsberg Maritime has been selected to deliver a fully integrated equipment package for a next-generation ultra-large cable laying vessel being built for LS Marine Solution at Tersan Shipyard in Türkiye.
The vessel, set to be among the world’s largest cable layers, is being developed to address the growing global demand for laying subsea high-voltage direct current (HVDC) cables and optical cables.
The vessel will be 148m long and 31m wide, with cable carrying capacity and total displacement of 13,000 tons and 18,800 tons respectively.
Kongsberg Maritime’s delivery includes K-Pos dynamic positioning systems, integrated control and navigation systems, a battery hybrid DC electrical system, as well as all main propulsion and thruster units.
Nazım Yasar, project manager at Tersan Shipyard, said, “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. With Kongsberg Maritime’s expertise and integrated systems, and LS Marine Solution’s vision, we are confident that this partnership will deliver outstanding results for the industry.”
Leszek Kopec, senior sales manager at Kongsberg Maritime, said the company has focused on “reducing CAPEX, OPEX, space, weight, and emissions, while ensuring the vessels’ operability and efficiency.”
He added, “This project reflects Kongsberg Maritime’s consistent commitment to applying our in-house domain knowledge of cable lay operations to optimize marine systems and mission system integration. It represents our fifth fully integrated system award for cable lay vessels within the past year.”
The battery hybrid DC power and propulsion system is said to reduce the number of engines required during operations, by virtue of its high efficiency. A high-capacity shore connection, supported by the battery system and KM’s Energy Control System, enables zero-emission operations during port stays and cable loading activities.
According to Kongsberg, this configuration significantly lowers greenhouse gas emissions and aligns with global ESG standards, positioning the vessel as a key enabler of sustainable HVDC grid expansion and the offshore renewable energy transition.
The K-Pos DP systems and permanent magnet motors installed on the azimuth thrusters are predicted to deliver enhanced safety, operational efficiency and positioning accuracy.
The design also supports the mobilization of Kongsberg Maritime’s Remote Cable Pull-In systems for floating wind farms, which enables pull-in and hang-off operations of dynamic cables without personnel transfer or crane-based equipment handling.
Construction of the vessel at Tersan Shipyard is expected to take approximately three years, with the vessel planned to enter operation in 2028.
