XLCC CLV Vessel Unveiled as Next-Generation Cable Layer
XLCC, a new U.K.-based business focused on renewable energy and high-voltage direct current (HVDC) technologies, has completed the concept design of its advanced cable-laying vessel, the XLCC CLV. This first-of-its-kind ship will be delivered in the first half of 2025 and set new benchmarks in subsea cable installation.
The XLCC CLV vessel will play a key role in delivering four 3,800-kilometer subsea HVDC cables for the Morocco–U.K. Power Project — a large-scale wind and solar energy initiative connecting North Africa and the U.K.
Advancing the Global HVDC Market
XLCC Director Alan Mathers described the project as a major step forward in renewable infrastructure. “Our vessel will be the most sophisticated, capable, and green cable layer in the world,” Mathers said. “With this capability, we can meet growing global demand for HVDC cable deployment and bridge the existing market gap.”
By leading this innovation, XLCC aims to support both large-scale green energy projects and the industry’s transition to sustainable offshore power transmission.
Collaboration and Design Development
The XLCC CLV vessel is being developed in partnership with Salt Ship Design, with support from MAATS Tech and Global Marine for cable-handling systems. The design uses advanced 3D engineering software to optimize steel structures, cable storage, and interior layouts.
XLCC’s engineers are currently finalizing the vessel’s basic design and planning construction with a selected shipyard to begin soon. This integrated design approach ensures efficiency, sustainability, and readiness for large-scale cable operations.
Engineering the Most Advanced CLV Ever Built
According to the company, the XLCC CLV vessel doubles the cable capacity of the largest ships currently in service. The design allows significantly more cable per voyage, which reduces transit times, operating costs, and fuel emissions.
Key performance highlights include:
-
Loading and deployment speeds optimized to align with cable production schedules
-
Dual below-deck cable carousels for increased operational efficiency
-
Transit speed of approximately 15 knots loaded and 16 knots returning to port
-
Reduced harbor turnaround time through faster cable loading and optimized workflows
Sustainable Technology for Future Operations
Sustainability remains central to the XLCC CLV vessel design. The ship will operate with low- or zero-emission fuels, including liquid organic hydrogen carrier (LOHC) and methanol, alongside marine gas oil (MGO) capability.
Its 110-meter hangar, larger than traditional CLVs, maximizes internal workspace. Additionally, the aft-positioned superstructure improves vessel balance, speed, and fuel efficiency, ensuring top performance during global HVDC cable missions.
Shaping the Future of Renewable Connectivity
With the XLCC CLV vessel, XLCC positions itself at the forefront of clean energy infrastructure. This groundbreaking ship combines high capacity, lower emissions, and faster performance — setting a new global standard for subsea cable operations.
