Energinet has selected MMT to conduct the initial surveys of the seabed area for Denmark’s planned ‘energy island’ in the North Sea. The artificial island in the North Sea is set to be the world’s first offshore wind energy hub
MMT, which was recently acquired by Ocean Infinity, will conduct pre-construction geophysical and seismic surveys in the 526 km2 area from May 2021 to September 2022.
The work will be carried out in four phases. Phase 1 will deliver the geophysical survey including 2D surveys down to 100 m below the seabed.
Phase 2 will see the deployment of remotely operated vehicles to conduct unexploded ordnance (UXO) magnetometer surveys.
Phase 3 is a 3D ultra-high resolution seismic survey of the site for the energy island, followed by the final phase, a survey and inspection to assist the Danish Navy with the removal of confirmed UXO.
The work will be used to produce a detailed digital map of the seabed and underlying geological layers to allow construction of the artificial island and around 200 offshore wind turbines in both a technically feasible and environmentally conscious manner.
Once established, the island will convert and distribute power to several countries. Initially it will produce 3 GW of power, increasing to 10 GW.
Energinet project manager Poul-Jacob Vilhelmsen said, “The geophysical studies have to cover a very large area, and it is important that they meet the time schedule.”
