Global electrification company Nexans has achieved a new technological milestone by installing a subsea cable at an unprecedented depth of 3,000 meters during a deep-water sea trial.
The test was carried out as part of the company’s GSI (Generation Subsea Interconnector) project, with the achievement announced from Oslo, Norway. Engineers successfully deployed the cable to the ocean floor during the trial, marking the deepest subsea cable installation ever attempted.
The project was conducted using Nexans’ specialized cable-laying vessel, Nexans Aurora, which is designed to handle complex offshore installation projects. The vessel used advanced equipment and remotely operated technologies to precisely position the cable at extreme ocean depths.
According to the company, the record-setting test demonstrates the feasibility of installing subsea power cables in ultra-deep waters, a capability that could significantly support future offshore energy projects and long-distance power connections.
Industry experts say the breakthrough could play an important role in expanding renewable energy infrastructure, particularly for offshore wind farms and international electricity interconnectors.
