​ The probable cause of the collision between the American Dynasty and the Winnipeg was the insufficient planning between the American Dynasty’s master and chief engineer regarding vessel arrival procedures and emergency maneuvering, and the poor crisis communications between the bridge and the engine room. Contributing to the accident was the status and condition of the American Dynasty’s emergency generator and emergency batteries, which were not prepared to supply power at a critical time.

​​​​General Tips for Safe Vessel Transits and Emergency Maneuvering

Before a vessel transit, establish a plan outlining procedures and expectations for departure, arrival, and key points along the way. Plan ahead for potential emergencies and how to resolve them. Have critical stations manned by qualified personnel at key points in the transit. Always be prepared to act when necessary.

Pay close attention to the following factors. Test your systems (1), and train your crew accordingly:

• Auxiliary and emergency equipment is set to activate automatically should your primary equipment shut down. It should be well maintained and up to date.
• Emergency batteries are in good condition, charged, and tested.
• Various alarms and shutdown mechanisms on board the vessel are set to activate properly in an emergency. The whistle should function correctly.
• A functioning backup system is in place for communicating should your primary method fail, and everyone knows how to use it.​
