  • Two-thirds of marine transportation accidents involve human factors, such as misunderstanding or ignoring hazard warnings, operating in adverse conditions without adequate weather monitoring, and navigational errors.
  • Over one-fifth of accidents are caused by a failure of vessel equipment, such as deck machinery, generators, propulsion controls, and fuel systems.
