DeepOcean has secured a notable offshore decommissioning contract on the UK Continental Shelf from an international operator, marking a significant milestone for its Aberdeen office. This contract involves a comprehensive decommissioning campaign scheduled to span over 120 days in 2024, divided into five sub-campaigns.
The project will include the recovery of concrete mattresses, spools, flexibles, flowlines, jumpers, suction anchors, multiple structures, and final debris clearance. Additionally, a subsea rock installation campaign will be conducted for final seabed remediation. DeepOcean plans to utilize its advanced fleet, including the Edda Freya with a 2300 m² deck space and a 400Te active heave-compensated crane, alongside two moonpool-launched 220 HP Kystdesign work-class remotely operated vehicles (WROVs). The Normand Jarstein vessel will also be deployed.
Recovered items will be transported onshore for reuse, recycling, or disposal, in compliance with stringent environmental regulations. DeepOcean aims to explore reuse options for all concrete mattresses through collaboration with a selected waste management contractor.
Gary Scott, UK Commercial Manager & Legal Counsel at DeepOcean, expressed delight over the contract award, highlighting the team’s proficiency in handling complex subsea projects with a focus on safety, environmental responsibility, and efficiency.
