The UK Marine Accident Investigation Department (MAIB), by way of Security Digest 1/2025, shared insights from current marine incidents. The Worldwide Marine Contractors Affiliation (IMCA) has highlighted a case involving crew harm throughout mooring operations for member consciousness.
What Occurred
A crew member sustained critical finger accidents throughout a mooring operation involving a young and a barge on a busy river. The tender, with two employees onboard, approached the barge, which already had two vessels moored alongside. To safe the tender, a crew member linked a mooring rope between a cleat on the tender’s port shoulder and a cleat on one of many moored vessels. Because of the tender’s considerably decrease freeboard, the rope was angled steeply. River present induced the tender to maneuver, and the mooring rope slipped off the cleat. Because the crew member tried to resecure it, the wash from a passing vessel induced the tender to heave. The crew member’s fingers had been caught within the bight of the rope because it was positioned again on the cleat, leading to extreme crush accidents.
Why It Occurred
The incident was primarily brought on by relative motion between vessels throughout mooring. Key contributing elements included a steep rope angle brought on by the distinction in freeboard between the vessels, dynamic forces ensuing from the river present and wash from passing site visitors, and the crew member’s hand positioning whereas trying to reattach the mooring rope. These situations created a sudden pressure within the rope, resulting in the entrapment and harm.
Actions Taken
The skipper responded promptly to the incident by transporting the injured crew member ashore for emergency medical therapy.
Classes Discovered
Relative vessel motion can introduce entrapment hazards throughout mooring. The crew should stay vigilant always.
Preserve fingers and fingers properly away from cleats and cord bights, particularly when vessels are affected by present or wave wash.
The place routine operations contain uneven freeboard or angled mooring traces, assess and adapt cleat design or mooring strategies to reduce rope slippage.
Conduct particular threat assessments for mooring operations involving vessel-to-vessel connections in dynamic environments.
