As a growing segment of trade conveyed by pure car/truck carriers (PCTCs), ro-ro multipurpose ships and ro-ro ferries, transportation of electric vehicles (EVs) presents new challengers for ship operators and crews.

In particular, the lithium-ion batteries that power EVs can enter a state of thermal runaway when damaged or defective, generating intense heat and flames that are difficult to control, and all the while giving off toxic gases. Traditional firefighting methods may be ineffective against these fires.

A raft of dramatic incidents over recent years involving conflagrations in shipments of EVs aboard PCTCs has raised concerns and underscored the need for shipowners and managers to adapt vessel designs, fire safety systems, handling procedures and crew training so as to enhance safety. Updated international safety standards for EV transport are expected to be introduced by 2027.
