Sunfish successfully reburies export cable Eneco Luchterduinen Wind Farm
For the offshore wind farm Eneco Luchterduinen, Jan De Nul was requested to rebury a section of an existing export cable. To this purpose, Jan De Nul modified its in-house designed and fabricated intertidal trencher Sunfish and successfully reburied the nearshore section of the cable to a minimum depth of 2.5 metres below the seabed. The work was successfully completed by mid-October.
Due to morphological changes the export cable burial was over the last few years decreasing in depth within the nearshore section. To guarantee the cable will at all times remain sufficiently buried and thus protected, a reburial campaign was requested by Eneco.
Since the section of decreased burial depth was located in the nearshore zone, it was not accessible with typical offshore trenching vehicles nor could it be easily accessed from the beach. Jan De Nul offered Eneco the solution by mobilizing its intertidal trencher Sunfish.
The Eneco Luchterduinen Wind Farm is located in the Dutch sector of the North Sea, approximately 23 kilometres off the coast near Noordwijk. 43 Vestas V112 offshore wind turbines produce a combined capacity of 129 MW. From the Offshore High Voltage Station (OHVS) one 150 kV export cable of 25 kilometres directs the current to the shore.
