CNR International, EnQuest, TAQA and TotalEnergies currently estimate they will have to spend over £1 billion to decommission their UKCS subsea infrastructure over the next 15 - 20 years. This quartet of Operators have been working closely with the North Sea Transition Authority (NSTA) to investigate the feasibility and benefits of combining their UKCS assets to create a unified portfolio of subsea facilities for decommissioning. Commercial transformation is one of four focus areas in the NSTA’s Decommissioning Strategy, published last year. This involves the cultivation of a competitive, sustainable market – the enablers for which are a collaborative culture, decommissioning at scale and data transparency.
The operators started considering combining their decommissioning projects in one portfolio in 2018, but it was two years later that they narrowed the focus to subsea infrastructure. The group became the Subsea Decommissioning Collaboration (SDC), signed a charter and developed an Engagement Plan to guide their ongoing work. To support this work the NSTA has created a map and a dataset of the operators’ assets, which has been designed in response to the supply chain’s call for greater visibility of future workscopes.
SDC launch events are now complete and SDC are commencing an intensive round of engagement with the Supply Chain to identify partners in driving technical and technological innovation. This will inform whether combining the work into a single package will open up new ways of working and improve decommissioning efficiencies. The opportunity for innovation and the development of new technologies and methods of working, on a massive pool of assets could deliver unheard of efficiencies which would be both transformational within the UKCS and transferrable worldwide.
This is the Supply Chain’s opportunity to influence and be a part of this significant market opportunity and to help to deliver a step change in subsea decommissioning.
The summary presentation is below, together with a link to the facilities data set.
