Work starts on Dutch offshore wind site

NETHERLANDS: Onshore cabling work on Eneco and Mitsubishi Corporation's 129MW Eneco Luchterduinen offshore wind site, 23 kilometres off Noordwijk, west Netherlands, has started.

Onshore cabling work on the 129MW Eneco Luchterduinen offshore wind project has started

The onshore section of this cable, which is more than 8 kilometres long, will run from Noordwijk beach to a transformer substation held by grid operator Tennet in Sassenheim, where it will feed into the national grid.

Visser & Smit Hanab has started drilling work on a 596-metre section, with Joulz – an infrastructure company that is part of the Eneco Group – acting as the main contractor.

The electricity will be transported to the shore by a 23-kilometre 150kV cable embedded in the sea floor.

Korea's LS Cable & System was contracted in July to supply extra-high-voltage submarine cables and connectors for the project.

Mitsubishi acquired a 50% stake in Luchterduinen this year, with Dutch utility Eneco holding the remainder.  

Construction of the onshore section will take place in stages between October 2013 and December 2014, with the laying of cables beginning in early 2014.

Turbine construction is expected to start in summer 2014, with completion due at the end of 2015.

Van Oord will be responsible for installing the wind plant’s foundations and electrical infrastructure, including its offshore transformer station.

The international contracting firm will also supply the vessel that will be used to install the wind site’s 43 Vestas V112 3MW turbines. The value of the contract to Van Oord has been estimated at EUR 250 million. 

This offshore wind project comes five years after the completion of the last Dutch offshore wind site, the Eneco-owned Princess Amalia.
