What is a marine casualty?

A marine casualty refers to situations that can jeopardize the safety of a vessel and its crew or cargo. This broad definition encompasses various incidents, including collisions, groundings, fires, and onboard injuries, all of which can affect the navigation and operational integrity of a ship. Situations that compromise vessel safety extend beyond pollution incidents, include mechanical failures, and may result in the need for rescue or emergency assistance. The essence of defining a marine casualty lies in the impact on safety, making it a critical term in maritime law and safety protocols.

While the other options touch on aspects related to maritime incidents—such as pollution, legal matters, and weather—none encapsulate the comprehensive notion of what constitutes a marine casualty, which can arise from a wide range of scenarios involving significant risk to the vessel and those on board.
