Powering Global Subsea Electrification
Delivered in 2021, Nexans Aurora is Nexans Subsea Operations’ flagship cable-laying vessel, built to support the world’s most demanding offshore power and interconnector projects. Designed by Skipsteknisk and constructed at Ulstein Verft in Norway, the vessel plays a central role in expanding offshore wind capacity and strengthening electrical grids across Europe and North America.
From offshore wind connections to long-distance subsea interconnectors, Nexans Aurora is designed for complex installation work in challenging offshore environments, where uptime, precision, and power reliability are critical.
Key Facts
Nexans Aurora is equipped with six Bergen B33:45L6A generator sets delivering a total of 21.6 MW of onboard power. The engines support all mission-critical systems, including DP3 dynamic positioning, cable-handling equipment, propulsion drives, and hotel loads, enabling uninterrupted operations during complex subsea installations.
Bergen’s medium-speed engines are selected for their reliability, fuel efficiency, and long service intervals, ensuring stable power during long-duration offshore campaigns where operational consistency is essential.
Enabling the Energy Transition at Sea
Nexans Aurora has already played a key role in major electrification projects. In Europe, the vessel supported the Greece–Crete subsea interconnector, one of the largest DC interconnection projects in the region, strengthening grid resilience and enabling large-scale renewable integration.
In the U.S., the vessel is contributing to the Empire Wind offshore project, delivering clean energy to more than one million homes. With reliable onboard power from Bergen Engines and a design focused on precision, endurance, and efficiency, the vessel sets a new benchmark for offshore electrification projects worldwide.
