Two pieces of breathing equipment on a ship look similar and are constantly confused. One lets a firefighter enter a burning space. The other only buys a few minutes to escape one. Mixing them up, or letting either run down, is a deficiency that recurs on inspection after inspection.
A liferaft can sit in its canister for years and look perfect from the outside while quietly going out of certification. The rules that keep it valid are strict, specific, and easy to trip over, and an inspector checks two separate dates that operators routinely assume are one.
Every ship over 500 tons carries a Safety Management System. On the best-run vessels it shapes how the crew actually works. On too many others it is a binder that comes off the shelf when an auditor arrives. The gap between those two states is where accidents and detentions live.
A fire in a ship’s engine room has to be fought by a system that was chosen years earlier, on a drawing board. Pick the wrong extinguishing system for the space, and the mistake is built into the vessel. Here is how CO2, water mist, and foam are matched to the hazard.
Immersion suits are built to keep a person alive in freezing water. In the warm seas of Southeast Asia, the rules allow some ships to leave them off. That single exemption creates more inspection confusion, and more risk, than almost any other item in the life-saving locker.
Two of the most dangerous jobs in the industry are climbing a flare stack and entering a storage tank. A drone can now do the first look on both without a single person leaving the ground, and increasingly the classification societies accept the result.
