At 1137 on 4 May 2017, the UK registered container ship CMA CGM Centaurus made heavy contact with the quay and two shore cranes while under pilotage during its arrival at Jebel Ali, United Arab Emirates. The accident resulted in the collapse of a shore crane and ten injuries, including one serious injury, to shore personnel.

The accident occurred because the ship was unable to attain a sufficiently high rate of turn into a basin in preparation for berthing. The pilot was unaware of the ship’s speed, and the ship’s bridge team were uncertain of the maximum speed required to complete the turn safely.

There was no agreed plan for the intended manoeuvre, and therefore no shared mental model between the bridge team and the pilot. Consequently, the pilot was operating in isolation without the support of the bridge team, allowing the pilot’s decision-making to become a single system point of failure.
