Summary
Investigation of two gangway failures at the Oseberg H–Island Clipper interface in 2025. Hydraulic coupling failures disabled gangway functions and the primary evacuation route, requiring helicopter evacuation without injury. The report distinguishes a likely May material defect from October assembly deficiencies and examines shared hydraulic dependencies, change management and emergency drills.
