After six years of producing a best-selling decommissioning report for the Gulf of Mexico, DecomWorld brings you the first report of its kind focused on the North Sea.

The new report will be a one stop shop for all your decommissioning needs and will include:

  • Expert analysis and commentary on oil and gas decommissioning project case studies in the North Sea which will enable operators to develop and deliver your own cost effective strategies
  • Gain first-hand project information and experiences on technical risks, cost risks and scheduling risks for decommissioning projects
  • Inform strategic planning for decommissioning projects and campaigns with a guide to best practices
  • The cost integration process throughout the project lifecycle which will help provide a greater understanding to deliver the most effective decommissioning processes

Industry Overview

Decommissioning in the North Sea is maturing as the industry experiences a transition towards greater levels of project activity over the next few years. The UK Department of Energy and Climate Change (DECC) has recently announced that they are experiencing the highest level of decommissioning programmes going forward, with plans for over 25 programmes expected over the next 2 years. With a number of major and independent operators approaching significant decommissioning projects in the North Sea for the first time, the industry is facing an era of new opportunities and challenges.

The current low oil price environment means it has never been more important to manage financial liabilities, such as decommissioning. As the number of projects underway increases, companies must establish effective organisational structures and strategic approaches to meet the diverse challenges ahead, while controlling costs. DECC figures currently estimate 14% year on year upward revisions of decommissioning estimates, with average budget overruns at 60%. If these figures are to be improved, new strategic approaches are required. This report from Decomworld brings you insight and experience from headline decommissioning projects in the North Sea, delivering a solid reference point for future project planning.

Key reasons to purchase this report

  • Plan Costing: Successful cost reduction and budget management initiatives operators can employ which will aid in the financial planning of decommissioning projects.
  • Achieve Effective Delivery: The most effective methods for decommissioning structures and installations to date.
  • Understand Key Risks: Insight into the technical, regulatory and other risks major decommissioning projects in the North Sea have faced.

This report answers the following questions:

  • What strategic approaches have operators in the North Sea taken towards decommissioning projects & how successful have these been?
  • How can a portfolio of decommissioning projects be successfully managed to achieve the optimum equilibrium between scheduling and costing?
  • What specific industry lessons learned from past projects can be used to improve the performance of future work?
  • What are the overarching practices, standards, and regulatory requirements that drive the performance of North Sea removals and decommissioning?
  • What are the best practices when budgeting and cost planning for a project? How can operators control their costs on decommissioning projects?
  • How can operators control their costs on decommissioning projects?
