Sandbank offshore wind farm
As part of a joint venture with German partners GSS HANSA Offshore, James Fisher Subsea undertook an unexploded ordnance (UXO) project in German waters.
Delivering innovative UXO solutions to the renewable energy market, JF Subsea project managed the identification of 120 potential contacts of which 28 were highlighted as UXOs and disposed of in a controlled environment.
Utilising in-house expertise and assets, JF Subsea worked with German partners GSS Hansa Offshore GmbH to deliver a safe and efficient project solution. Capable of working in German waters aligning with federal law, the project was delivered a head of schedule and within budget which was acknowledged by the customer.
Operating in the German North Sea at the location of the Sandbank wind farm, the second largest power generation project undertaken by Vattenfall, JF Subsea utilised in-house ROV and UXO assets and industry leading expertise to deliver a complete subsea engineering solution.
Capability demonstrated included the relocation of contacts using state-of-the-art surveying equipment, excavation contacts using dredging tools on a work class ROV, identification of contacts by qualified UXO experts and disposals.
Capabilities included controlled ROV operations, vessel utilisation by identifying and disposing of the UXOs from the same vessel, which enabled a safe and robust approach to save time and speed up project delivery – further reducing costs throughout project delivery.
