Summary
A platform supply vessel suffered partial loss of propulsion after a mooring rope entered the water and fouled its port propeller. The flash identifies deficient planning, risk assessment and communication during mooring, including delayed notification to the bridge. Lessons emphasise coordinated communication, more detailed risk assessment and stopping work when in doubt.
