How is a marine casualty defined?

A marine casualty is defined as an event that materially affects a vessel's safety. This definition encompasses a range of incidents that can compromise the operational integrity of the vessel, including accidents that might lead to injury, loss of life, or significant damage to the vessel itself or its equipment. The focus here is on the impact of the event on the safety and seaworthiness of the vessel, highlighting that any incident that threatens a vessel's ability to operate safely qualifies as a marine casualty.

The importance of this definition is underscored by the need for proper reporting and investigations following such incidents, as they are critical for improving safety standards and preventing future occurrences. Understanding this definition is crucial for mariners and those involved in maritime operations, as it assists in identifying situations that necessitate immediate action or follow-up reporting to regulatory bodies.
