The expansion of offshore wind energy and high-voltage electrical grids depends on infrastructure that often remains outside the public spotlight: LS Cable Marine Solution and the specialized vessels capable of installing hundreds of kilometers of submarine cables with millimeter precision.
In this context, LS Marine Solution, a subsidiary of LS Cable & System, initiated the construction of a new Cable Laying Vessel (CLV), designed to serve HVDC transmission projects, international interconnections, and next-generation offshore wind farms.
With a cable load capacity of approximately 13,000 tons, it will be the largest vessel of this type operated by a South Korean company and will enable the execution of long-distance installations in a single campaign, reducing operation times and risks associated with multiple submarine splices.
CLVs are an essential component of the energy transition
The accelerated expansion of offshore wind farms and international electrical links has increased the demand for specialized vessels capable of transporting, handling, and installing power cables under complex environmental conditions.
Unlike a conventional cargo vessel, a CLV integrates dynamic positioning systems, large carousels for cable storage, controlled tension equipment, and burial devices that enable the installation of conductors with high precision on the seabed, preserving both their mechanical integrity and electrical performance.
HVDC networks drive a new generation of infrastructure
The new CLV has been designed to respond to the growth of projects based on high-voltage direct current (HVDC), a technology that has become the standard for transmitting large blocks of energy over long distances with lower electrical losses than conventional alternating current systems.
HVDC connections play a strategic role in the integration of offshore wind farms located far from the coast, interconnections between countries, and electrical grids capable of transporting large amounts of renewable energy to major consumption centers.
LS Cable integrates manufacturing and installation within a single value chain
The construction of the new vessel is part of a broader industrial strategy developed by LS Cable & System to integrate the manufacturing and installation of submarine cables within a single supply chain.
The future entry into operation of LS GreenLink in the United States will enable the complementation of regional cable production with proprietary offshore installation capacity, offering integrated solutions for projects in North America and Europe.
This approach reduces dependence on external contractors, improves coordination between manufacturing and execution, and optimizes the logistical planning of large-scale projects.
