The seabed beneath the future energy island in the North Sea has to be thoroughly surveyed and mapped before work on building the island and the large offshore wind farms around it can commence. Energinet has just awarded survey assignments to two experienced marine survey companies who are expected to set sail in the North Sea in May.
The two companies are Fugro and MMT. Their ships are loaded with seismic equipment to meticulously map the seabed under the more than 1,000km
2 area in the North Sea where the artificial energy island and 3GW of wind farms are to be built.
The geophysical surveys will start in May and cover over 1000km square, Energinet said.
The surveys, together with later drilling samples, will result in a detailed, digital mapping of the seabed and the geological layers up to 100 metres below ground, it added.
Fugro said it will perform geophysical and unexploded ordnance magnetometry surveys from May to November 2021, resuming in February and March 2022.
Phase one will deliver the geophysical surveys, including seabed sampling and soil data, while the second phase will be the UXO magnetometry survey, using Fugro’s dedicated Geowing solution.
Fugro’s offshore wind consultancy teams will use the acquired data to provide a derisked site interpretation.
Energinet has awarded Fugro a marine site characterisation contract for the Danish Energy Island project in the North Sea. The contract is part of Ene.
