That risk has been put under the spotlight by the burning car carrier drifting off the Dutch coast. The Dutch coastguard said the fire's cause was unknown, but Dutch broadcaster RTL released a recording in which an emergency responder is heard saying "the fire started in the battery of an electric car."
Dutch news agency ANP, citing operator "K" Lines, said there are almost 4,000 cars on the ship. That total includes 25 EVs. "The first question that comes to mind is: Does the current code stack up against the risk profile of this type of goods?" he added. Recent fire-related losses are resulting in increased insurance costs for automakers shipping cargo and costs are likely to increase for vessel owners as well, said John Frazee, a managing director at insurance broker Marsh. As ship owners seek to limit losses by legally pursuing automakers whose vehicles are determined to have caused a fire, automakers are buying additional liability protection, he said.
Firemen typically put out EV battery fires on roadsides by clearing the area around the burning vehicle and flooding the underside with water, something difficult to do on a RoRo, Dillon said. Frazee expects insurers to lead the charge on strengthening safety systems on ships. Options being worked on include new chemicals to douse flames, specialized EV fire blankets, battery piercing fire hose nozzles and proposals to segregate EVs.The International Maritime Organization, which sets regulations for safety at sea, plans to evaluate new measures next year for ships transporting EVs in light of the growing number of fires on cargo ships, a spokesperson told Reuters.
