Nexans Marine Operations AS

Nexans Marine Operations AS is a subsidiary of Nexans Norway AS that owns and operates the group’s dedicated fleet of high‑voltage subsea cable installation vessels and related marine assets. Working globally across offshore wind, subsea interconnector and offshore electrification markets, the company executes turnkey marine scopes within Nexans’ projects, including transport, laying, jointing, protection, recovery and repair of high‑voltage subsea power cables and umbilicals. Its activities are central to Nexans’ role in providing turn‑key subsea high‑voltage systems for the electrification of offshore installations, cross‑border power links and offshore renewable energy projects. The fleet includes the DP3 cable‑laying vessels Nexans Aurora and Nexans Electra, together with the long‑serving cable layer Nexans Skagerrak and chartered support tonnage. Nexans Aurora is designed to handle deep‑sea and near‑shore cable installation in harsh conditions, with a large split turntable mid‑ships, a fibre‑optic basket and dual deep‑water and shallow‑water lay lines, and has been classed with DP3 and Silent‑E notations to enhance safety and reduce underwater noise. Nexans Electra, an updated ST‑297 design under construction for delivery in 2026, will feature three turntables with 13,500‑tonne loading capacity, the ability to lay up to four cables simultaneously, and a hybrid power system capable of operating on biodiesel blends. The company also employs the purpose‑built Skagerrak cable layer for major export cable campaigns such as the Dieppe–Le Tréport offshore wind farm, where Nexans has full responsibility for design, manufacture, installation, protection and long‑term IMR services. To extend near‑shore capability, Nexans Marine Operations supports a Jones Act‑compliant cable‑lay barge developed with Crowley Wind Services for U.S. offshore wind and subsea transmission work, equipped with a large cable carousel, dynamic positioning and vertical injector burial systems. Construction of Nexans Electra and associated marine investments are being funded through capital injections and loans from Nexans Norway, backed by cash generated from ongoing operations, in line with wider Nexans group commitments to support the energy transition while reducing environmental impact and progressing towards net‑zero by 2050.
