The North Sea's next chapter

These leaders represent different parts of the North Sea ecosystem—from production and field development to infrastructure, regulation, investment and the energy transition. Their decisions will influence how Britain manages its remaining offshore resources, develops major projects, maintains energy security and ultimately repurposes or decommissions infrastructure as the basin enters its next chapter.
