This document discusses emergency preparedness for offshore oil and gas installations in the North Sea over the past 25 years. It outlines a tiered approach to emergency response, with installation-level incident response teams (Tier 1), regional emergency response teams (Tier 2), and corporate crisis management teams (Tier 3) coordinating response at higher levels of severity. Onshore, integrated emergency response rooms and dedicated response teams work with regulators and contractors. Regular training and exercises help ensure all personnel are prepared to respond effectively in the event of an offshore incident.
