Ulstein Verft delivered the Nexans Electra to Nexans, a DP3 dynamically positioned cable-laying vessel built to enhance the installation of subsea power and communication systems. The vessel expands Nexans’ operational capacity in projects related to offshore wind energy, electrical interconnectors, and critical subsea infrastructure.
Furthermore, the vessel arrives at a time when demand for high-capacity submarine cables continues to grow due to the advancement of offshore electrification and cross-border connections.
With this delivery, Nexans’ fleet adds a specialized platform for complex operations of laying, protecting, repairing and splicing submarine cables.
A DP3 cable-laying vessel for demanding operations
The Nexans Electra was designed to operate offshore under adverse weather conditions and maintain stable performance during precision installation work. Its DP3 dynamic positioning system allows it to maintain the vessel’s position during critical maneuvers, which is essential when working with long power cables.
The vessel is also equipped to transport and lay submarine power cables, including communication and fiber optic systems. This configuration allows it to handle projects where operational safety, maneuverability, and work continuity are critical factors.
Greater capacity for submarine cables
The CLV Nexans Electra is a sister ship to the Nexans Aurora, delivered by Ulstein Verft in 2021, although it incorporates an updated configuration and greater cargo capacity. Its main features include a below-deck turntable with a capacity of 3,500 tons of cable, a split deck turntable for up to 10,000 tons, and a fiber optic tank with a capacity of 450 tons.
Furthermore, these capabilities allow the vessel to handle large-scale installation campaigns without relying on frequent logistical cycles. This is particularly useful for electrical interconnection projects, offshore wind farms, and submarine networks that require extensive cable runs and high precision during installation.
Once in service, the Nexans Electra will be used in marine renewable energy and interconnection projects in various regions around the world. Its specialized equipment positions it as a key asset for the installation of export cables, submarine power links, and turnkey solutions for power transmission systems.
In addition, the vessel can support recovery, repair and splicing work, functions that are increasingly relevant to the resilience of underwater networks.
Collaboration between Ulstein and Nexans
Ulstein Verft was responsible for the turnkey delivery of the vessel, including outfitting and completion at its shipyard in Ulsteinvik, Norway. The construction confirms the Norwegian group’s expertise in specialized vessels for the offshore and energy markets.
For its part, Nexans is strengthening its cable-laying fleet with a vessel equipped for highly complex subsea projects. This delivery also consolidates the relationship between the two companies, which had already gained momentum with the Nexans Aurora and now adds a new vessel geared towards the global energy transition.
