Kongsberg Maritime to Equip LS Marine’s Ultra-Large Cable Lay Vessel

Why It Matters

The vessel addresses rising global demand for high‑capacity subsea cable installation while showcasing ESG‑focused marine technology, giving LS Marine a competitive edge in offshore energy markets.

Key Takeaways

• Kongsberg supplies integrated systems for LS Marine’s CLV.
• Vessel capacity: 13,000 t cable, 148.4 m length.
• Battery‑hybrid DC propulsion enables zero‑emission port operations.
• Permanent‑magnet thrusters improve positioning accuracy and efficiency.
• Supports remote cable pull‑in for floating wind farms.

Pulse Analysis

The surge in offshore wind and intercontinental power transmission is driving a need for larger, more capable cable‑laying vessels. By equipping LS Marine’s 148‑metre platform with Kongsberg’s end‑to‑end marine systems, the project positions the ship to handle the growing volume of high‑voltage direct current (HVDC) and fiber‑optic cables required for next‑generation energy grids. This capacity boost not only accelerates project timelines but also expands the addressable market for shipbuilders and equipment suppliers alike.

A standout feature of the vessel is its battery‑hybrid DC power and propulsion architecture, which reduces the number of diesel engines needed during operations and enables zero‑emission mode while docked or loading cable. Integrated with Kongsberg’s Energy Control System, the high‑capacity shore connection and onboard batteries meet tightening ESG regulations and lower operating costs. The permanent‑magnet azimuth thrusters, combined with K‑Pos dynamic positioning, deliver precise station‑keeping essential for delicate subsea installations.

Beyond traditional cable laying, the ship incorporates Kongsberg’s Remote Cable Pull‑In technology, allowing operators to deploy dynamic cables for floating wind farms without crane handling or crew transfer. This capability streamlines offshore wind construction, reduces safety risks, and shortens project cycles. As the renewable sector scales, such versatile vessels will become critical assets, reinforcing Kongsberg’s reputation as a leader in marine automation and positioning LS Marine to capture a larger share of the burgeoning offshore infrastructure market.
