Nexans, a global leader in advanced cable and energy solutions, has achieved a pivotal milestone in the construction of its next-generation cable-laying vessel (CLV), Nexans Electra, with the arrival of the hull at Ulstein Verft in Norway for the final outfitting phase. This marks a major step forward in Nexans’ mission to accelerate the global energy transition by enabling efficient, sustainable subsea power transmission.
As the global energy landscape evolves, investments in offshore wind, interconnections, and deepwater electrification projects are accelerating. Nexans Electra is a strategic response to this growing demand: a high-capacity, state-of-the-art vessel designed to deliver power where it is needed most, with unparalleled efficiency, durability, and precision.
Designed to meet the challenges of a low-carbon future, Electra will significantly strengthen Nexans’ capabilities in turnkey projects for the installation of submarine cables, thus consolidating its position as a world leader in offshore energy transmission solutions.
The hull of the Nexans Electra—originally built at the Crist shipyard in Poland—has now arrived in Ulsteinvik, entering its critical fitting-out and completion phase at Ulstein Verft. Scheduled for delivery in 2026, Electra will become one of the world’s most efficient cable-laying vessels, designed to meet the growing complexity of today’s and tomorrow’s energy infrastructure.
Once completed, the ship will be equipped with:
- A 10,000-ton divided carousel on the bridge
- A 3,500-ton carousel under the bridge
- A 450-ton tank dedicated to optical fiber
This equipment will enable Electra to transport and lay large volumes of high-voltage submarine cables, both direct current (HVDC) and alternating current (HVAC), and to carry out complex construction and repair operations in deep waters.
At the Ulstein Verft site, the vessel is now entering its fitting-out phase: electrical installation, insulation, piping systems, etc. The shipyard will also install essential equipment, such as the main generator, power and propulsion systems, winches, deck equipment and topside installations.
At 155.2 meters long and 31 meters wide, Nexans Electra is designed to operate in extreme conditions, with excellent positioning and optimal maneuverability. The vessel will also be equipped with a shore power connection system, an energy storage system, and will be compatible with biofuels – all solutions designed to significantly reduce its environmental footprint.
Nexans Electra will play a pivotal role in the global energy transition, increasing Nexans’ ability to deliver turnkey submarine cable projects with speed, precision, and resilience. From deepwater construction to high-voltage transmission, this vessel will be at the forefront of offshore innovation, serving customers and communities worldwide.
