N-Sea Awarded Renewables Unexploded Ordnance Contract
Subsea IMR provider, N-Sea, has been awarded a contract with Galloper Offshore Wind Farm Ltd (GWFL). The contract for pre-construction unexploded ordnance (UXO) clearance works commenced in April 2016 and includes UXO risk management, target investigations and clearance on the Galloper Wind Farm, off the coast of Suffolk. Expected to run for between 3-6 months, the project sees the Siem N-Sea multi-support vessel utilise a WROV to investigate potential UXO targets within the array areas and export cable corridor. N-Sea’s dive support vessel, Neptunus, will also undertake similar tasks in shallow water areas.
To complete the clearance works, N-Sea has sub-contracted Ordtek Ltd (provider of unexploded ordnance risk management for land and marine developments), Modus Seabed Intervention (work class ROV and crew hire) and Ramora UK (Explosive Ordnance Disposal services).
Heavily Mined Area
Ordtek Ltd recently launched a Mine Map sharing information regarding UXO around the UK coastline. The map illustrates that the Galloper area, was heavily mined in the First and Second World Wars, and has been an active British military training area.
Ordtek director Lee Gooderham added this is significant and complex project, with considerable ordnance that was previously found at the neighbouring Greater Gabbard site.
