“A properly functioning bridge team requires that all its members maintain a shared mental model to actively monitor a ship’s progress,” Mr Mitchell said. ”This relies on relevant information being conveyed to all members of the team, and actions that are incorrect being identified, communicated and rectified immediately.”

Due to the action of the tugs and bow thrusters, the Maersk Shekou continued to maintain a port swing of about 10°/min, away from the direct path of the STS Leeuwin II. However, Maersk Shekou did not make a clear turn, and moments later, its starboard bow flare collided with the STS Leeuwin II, dismasting the latter. Two crew members, on board the sailing vessel at the time, escaped via its gangway just as the collision occurred.

“The Leeuwin has been absolutely smashed to pieces,” a witness said on Radio 6PR Australia. “None of its mast is standing, and it’s listing over and hanging over onto the port.”
