Challenging the base case


The growing decommissioning activity in the North Sea is forecast to cost £47 billion. With the government’s drive to reduce this cost by 40%, the industry and supply chain must make significant cost savings during decommissioning. In order to achieve these reductions in cost safely, there is an inherent need to challenge the way that decommissioning has been performed to date.

The intent of many recent decommissioning projects has been to remove all subsea components to leave a clear seabed. However, is this really the most suitable solution from an environmental and safety perspective? In this webinar, Graham will discuss the arguments for and against derogation cases.

Process efficiency and innovation are also key to the reduction of decommissioning costs. With multiple operators tied into export hubs across the North Sea, the benefits of aligned decommissioning programmes, shared resource, campaigning and collaboration can be realised. This webinar will discuss these concepts as well as highlighting some of the recent innovations within decommissioning that have led to significant cost savings.

Ideal for anyone involved in the decommissioning of offshore oil and gas assets and infrastructure, this webinar takes a look at how decommissioning can be done differently to realise cost savings and environmental and safety benefits.

Learning objectives

  • Understand the need for innovation in decommissioning in order to improve process efficiency and safety whilst reducing the associated costs
  • Gain an insight into emerging technologies developed to overcome problems encountered during decommissioning and how they can be used to increase process efficiency
  • Appreciate the potential cost savings associated with collaboration and campaigning for your decommissioning projects
  • Gain an understanding of the current requirements surrounding the removal of subsea equipment and infrastructure from the seabed in the North Sea (including subsea structures and mattresses)
  • Consider how these requirements can be challenged to arrive at the most acceptable decommissioning solution (for all parties) through the associated derogation case


Graham Wilson, Head of Late Life at Jee Ltd

Graham is a chartered mechanical engineer with over 11 years’ experience working in the oil and gas industry. As Jee’s Head of Late Life, he is responsible for all lifetime extension and decommissioning projects performed by Jee.

Having provided consultancy services to customers at all stages of the decommissioning project lifecycle, Graham has developed a detailed understanding of the decommissioning process and the associated issues and challenges. His work has included everything from the development of decommissioning costing tools prior to the planning phase to the generation of best practice documentation for operators following project close-out.

The condition and fitness-for-purpose of ageing assets and infrastructure plays a key role in determining the approach to decommissioning, and Graham has led the provision of integrity management services to operators of assets in excess of 35 years old in the southern North Sea. Graham has also been integral in the writing of the ISO code for pipeline lifetime extension (ISO TS 12747), acting as convenor of the associated working group and producing the final document.
