Njord Survey has been contracted by Energean UK Ltd to provide post decommissioning site survey services at the Wenlock, Garrow and Kilmar fields in the UK Southern North Sea. The surveys will document the condition of the seabed after the platforms and exposed subsea infrastructure has been removed. The results will be compared with the pre-decommissioning surveys and will form part of the decommissioning close-out reporting for the three fields.
The contract covers seabed and environmental survey work along the pipeline routes and around the former platform locations.
Garrow and Kilmar and their pipelines lie within the Southern North Sea Special Area of Conservation, an important area for harbour porpoise. The work includes multibeam echosounder (MBES) and side scan sonar (SSS) survey, environmental sampling, analysis and reporting, as well as video transects and still photos.
Njord Survey is built on owning and controlling all resources itself. The company fully owns and operates its survey vessels, and all personnel are full-time employed. Njord Survey's vessels are streamlined and optimised for geophysical surveys, environmental sampling and light ROV work, which makes it possible to reduce CO2e emissions by 90% in projects.
“Decommissioning is only finished when it has been shown that the seabed is clear, and that proof has to stand up in front of the regulator. We own our vessels and our survey equipment, and the people doing the work are full-time Njord Survey employees. That gives Energean one accountable team and a spread that is ours to schedule, from the first survey line to the final report. The UK is our largest market, and this contract is an important step for us in the North Sea decommissioning sector”: Martin Wikmar, CEO, Njord Survey AB.
“Decommissioning is the final chapter in a field's life, and it is an important part of the project's long lifetime. We are proud that Energean has chosen Njord Survey as its partner for Wenlock, Garrow and Kilmar. From our very first meeting we have shared the same values: safety first, openness and a real commitment to doing things properly. Our role is to give Energean, the regulator and everyone who cares about the North Sea confidence that the seabed has been left in good condition. That is work our whole team is proud to stand behind”: Philip Ljungström, Project Director, Njord Survey AB.
“Energean is committed to safe, efficient and environmentally responsible decommissioning. These commitments do not end when the last structure is lifted. We also want to credibly show that we have left a clear seabed and that our decommissioning operations have had no long-term impact on the seabed environment. Njord Survey's work will give us that record for Wenlock, Garrow and Kilmar, supporting the close out of our decommissioning programmes with the regulator. Their commitment to safety and open, collaborative approach made them a natural partner for this final phase”: Andrew Shepherd, Head of Decommissioning, Energean UK.
