Summary
The PSA investigates uncontrolled diving-bell lowering aboard Skandi Arctic during saturation diving at Kneler. Umbilical separation caused pressure loss before the bell reached the water; divers closed leaking valves and restored pressure using stored gas. The report examines handling-system operation, management deficiencies, competence and emergency arrangements, with no known health consequences.
