Summary
A crane’s man-riding brake casing failed during preparation, dropping components to the deck without injury. Investigation identified hydraulic overpressure and incorrectly set relief valves, with commissioning changes insufficiently evaluated. The flash describes isolation by blanking and recommends valve adjustment checks and reviews of change management, commissioning, competence and maintenance procedures.
