Designed for the installation of electrical cables for offshore wind farms.

Full electrical scope

Alewijnse delivered the full electrical installation and systems integration on board the Nexus, the innovative new cable layer built by Damen Shipyards Group for international offshore contractor Van Oord. With the build taking place at Damen Shipyards Galati (Romania), the project was jointly managed by the Alewijnse location in Drachten in The Netherlands and Alewijnse Marine Galati, with both departments working on the engineering and project management.

The scope of the project included all the onboard electrical systems, as well as the installation of the propulsion drives and motors that make up the 122 metre vessel’s powerful diesel-electric DP2 system. Other aspects of the fit-out included the integrated bridge system and the electrical systems for the high quality accommodation. The total installed power on board Nexus is approximately 10 MW, with the two propulsion drives delivering 2 MW each.

Ahead of schedule

With the contract signed in October 2013 that left just 14 months for design, engineering and installation, the vessel was handed over to her owner ahead of schedule. For some time the Nexus was in Vlissingen, where Alewijnse worked alongside Van Oord on the electrical installations and systems integration for the cable laying equipment.


The 126m Nexus is an innovative cable laying vessel which is designed for the installation of power cables for offshore wind farms. The vessel has been equipped with a cable carousel with a capacity of more than 5,000 tonnes and an offshore crane that will enable it to lay heavy and long export cables. The vessel accommodates up to 90 persons.
