Summary
A rented hydraulic winch suffered bearing-housing failure during seabed load recovery, with no injuries. Investigation identified repetitive overload damage, inadequate braking and design calculations not updated after a spooling-device modification. The flash recommends routine non-destructive testing, revised design verification and a proper drum disc brake, while suggesting failure-mode analysis.
