Summary
Investigation of the February 2015 condensate leak on Gudrun examines fatigue rupture of separator-outlet bypass pipework, control-valve behaviour and severe vibration. It analyses valve sizing, multiphase flow, maintenance follow-up, communication and safety barriers, identifying weaknesses in integrated engineering assessment and the use of operating experience.
