Offshore decommissioning has evolved from an emerging challenge to a strategic imperative as aging infrastructure across the world's major offshore basins reaches end-of-life, driving unprecedented levels of investment, technical innovation, and regulatory scrutiny. What was once viewed primarily as an obligation is now recognized as a complex business challenge requiring excellence in engineering, execution, environmental stewardship, and value creation. This executive panel brings together industry leaders from four of the world's most active offshore decommissioning regions to share lessons learned, execution strategies, and emerging best practices from large-scale offshore retirement programs. Panelists will discuss: The Gulf of America's transition from mature asset ownership to large-scale decommissioning, including lessons learned from complex legacy asset retirement programs, liability management, and stakeholder engagement. Petrobras' experience advancing innovative decommissioning practices across one of the world's largest offshore portfolios, delivering improvements in safety, project efficiency, and cost performance. Execution excellence, contracting strategies, and supply chain optimization in the North Sea, one of the world's most mature decommissioning markets. The logistical, resource, and vessel-availability challenges associated with executing decommissioning campaigns in Australia's remote offshore basins. Beyond project execution, the discussion will explore how operators are incorporating circular economy principles into decommissioning programs through material recovery, waste reduction, emissions management, and responsible asset retirement. The session will conclude with a forward-looking assessment of the global offshore decommissioning market, including investment forecasts, regulatory developments, supply chain capacity, emerging technologies, and regional growth opportunities. Attendees will gain practical insights into how leading operators are managing risk, improving project performance, advancing sustainability objectives, and preparing for the accelerating wave of offshore decommissioning activity expected over the coming decades.
