Marine Casualties

Each year the U.S. Coast guard publishes a report summarizing statistics and information regarding inspections and enforcement of regulations on U.S. ? agged vessels. The handy account looks at de? ciency and detention rates for each type of inspected domestic vessel, among other things, including casualty events.

A reportable marine casualty includes any marine casualty consisting of a grounding, allision or collision; loss of main propulsion; occurrence materially and adversely affecting the vessel’s seaworthiness; a loss of life; an injury to a person which requires professional medical treatment; damage to property in excess of $75,000; or a discharge or release of a reportable quantity of a hazardous substance into the navigable waters. 46 CFR Subpart 4.05-1.

There were 1,644 reportable marine casualties reported in 2020 involving 1,956 inspected vessels, according to the

U.S. Coast Guard’s 2020 Flag State Control Annual Report. These totals were down from 2,095 casualties involving 2,561 vessels reported in 2019.
