Vattenfall Vindkraft A/S is seeking a contractor to carry out ROV inspection works of debris and potential UXO at its Horns Rev 3 offshore wind farm site off the Danish west coast.
The contract will cover ROV inspection of debris and potential unexploded ordnance in water depths of 10m to 20m, with electromagnetic detectors on an ROV for re-detection of anomalies identified during a previous survey and a forward-looking sonar and HD camera for live imaging from the ROV.
The works will also include debris removal and sand removal for exposure of buried objects.
Vattenfall also left an option to use the vessel as a platform for Explosive Ordnance Disposal (EOD) operations, which are not part of scope in the current invitation for tenders.
The works are planned to be performed during summer 2016 and will last for three months.
Deadline for the submission of tenders is 28 February, 2016.
In February last year, Vattenfall won the right to develop the 400MW wind farm comprising up to 51 MHI Vestas V164-8.0MW turbines.
