Nexans names its new cable laying vessel Nexans Aurora

The DP3 cable laying vessel Nexans Aurora was named at Ulstein Verft on 8 June 2021. The 149.9-metre-long and 31-metre-wide vessel boasts over 10,000 tonnes of cable load capacity and is fitted with state-of-the-art instruments for cable transport, installation, and protection.

The lady sponsor of the vessel is Mrs Anne-Lise Aukner, former Managing Director of Nexans Norway. Despite the Covid-19 pandemic, the project progress has been steady, and the vessel was delivered on time on 31 May 2021, three years after the signing of the shipbuilding contract. Watch a video of the sea trials below.

Once launched, cable laying vessel (CLV) Nexans Aurora will lay export cables for offshore wind farms and interconnectors around the world like for the Seagreen OWF in Scotland, the Crete-Attica interconnector in Greece and the Empire Offshore Wind project in US.

The vessel is an advanced CLV specially designed to install and maintain a large selection of submarine distribution systems, including installation of High Voltage submarine systems, bundled products, telecom systems and submarine umbilical systems. It is also suitable for inspection, repair and maintenance of submarine systems, cable system protection and trenching and general subsea survey and construction work.
