Summary
A hydraulic winch expelled a sensor and approximately two litres of oil during wire-rope installation. Findings identified reversed hydraulic hoses, improper commissioning, unauthorised testing and missed handover issues. Recommendations address crew communication, formal testing authorisation, risk assessment, pre-use checks and defining equipment condition before planned maintenance.
