SESSION 2 – RED TAPE, GREEN LIGHT: NAVIGATING REGULATIONS
  • 10.30 am - 11.45 am

SESSION 2 – RED TAPE, GREEN LIGHT: NAVIGATING REGULATIONS

Good regulation promotes market stability, builds trust, supports economic growth and fosters innovation. The UK has a long established regulatory system for the decommissioning of offshore oil and gas installations and pipelines and regulators frequently share the UK model with other nations. So why is the NSTA announcing plans to publish well decommissioning information and OPRED consulting on proposed updates to the process for considering derogations from OSPAR Decision 98/3?

In true “Question Time” format the panel will take questions from the audience to discuss the red tape or green light of the UK regulatory system.

Chaired by Andrew McCallum, CEO and Founder, Aspect

The panel will include:

  • Valerie Allan, Partner, CMS
  • Pauline Innes, Director of Decommissioning & Supply Chain, North Sea Transition Authority
  • Teresa Munro, Chief Operating Officer, OPRED

SESSION 3 – COLLABORATION IN ACTION
  • 1.00 pm - 2.15 pm

SESSION 3 – COLLABORATION IN ACTION

Exploring and showcasing real-world examples of effective collaboration throughout the UK decommissioning sector. The session highlights how industry partners work together to address the complex challenges of decommissioning offshore installations, drawing on a range of case studies from leading organisations. By bringing together representatives from Operator and supply chain, the session aims to demonstrate how joint initiatives and cooperative approaches can drive innovation, improve operational efficiency, and deliver successful outcomes. Through presentations and a panel discussion, attendees will gain valuable insights into the tangible benefits of industry collaboration and the ways in which these partnerships are shaping the future of decommissioning in the UK.

  • 4.20 pm - 5.30 pm

SESSION 6 – GLOBAL STANDARDS, LOCAL BLIND SPOTS: WHY EVIDENCE MUST LEAD DECOMISSIONING DECISIONS

Despite the clarity of international frameworks, such as OSPAR Decision 98/3 and it’s derogation provisions, decommissioning decisions across jurisdictions are often drowned out by inherited philosophies like a default push for a ‘clean seabed’ rather than be grounded in site-specific evidence. This session explores why economics, environmental science and technical feasibility, explicitly required by most jurisdictions should be central to evidence led decision making.

SESSION 7 – DECOMISSIONING IN THE ENERGY TRANSITION

At some point all energy infrastructure will require decommissioning and consequently this stage needs to be embedded into all the stakeholders thinking, policies, and investment decisions. Decommissioning should exist alongside the deployment of new energy systems, and not in competition, thereby allowing for a greater emphasis on sustainability and cost effective decision making.
