The Latest on the Wan Hai 503 Blaze
A massive fire continues to engulf the Wan Hai 503, a 7,000-TEU container vessel, off the coast of Mumbai, India. The incident, which began in the early hours of June 8, 2025, has prompted a multi-agency maritime rescue operation.
-
Rescued Crew: 18 seafarers were successfully airlifted and brought ashore by the Indian Coast Guard and local fishing boats.
-
Missing Personnel: Four crew members remain unaccounted for as search-and-rescue (SAR) teams scour the vessel’s decks and surrounding waters.
-
Injuries Reported: Five sailors sustained burn injuries and smoke inhalation; they are receiving treatment at Mumbai’s naval hospital.
-
Firefighting Efforts: Indian Navy tugboats and on-shore fire services are battling the blaze using high-capacity monitors and foam agents.
How the Fire Broke Out
According to initial investigations, the fire is believed to have originated in one of the cargo holds carrying lithium-ion batteries. Such cargo poses a high risk of thermal runaway, making fires difficult to suppress. Witnesses on nearby vessels reported an explosion followed by thick black smoke billowing from the ship’s midsection.
Rescue Operation
Within two hours of the emergency call, the Indian Coast Guard dispatched an interceptor boat and a helicopter. The chopper team air-dropped life rafts and hoisted 18 crew members from the burning deck. Meanwhile, fishing trawlers assisted in rescuing sailors who had launched lifeboats. SAR operations have now shifted to locate the four missing mariners, with divers preparing to enter the superstructure once the fire subsides.
Maritime safety experts warn that lithium-battery fires can reignite hours after initial extinguishing. “This incident underscores the need for stringent stowage regulations and advanced firefighting systems on containerships,” says Captain Ravi Menon, a former master mariner.
The Wan Hai 503 is operated by Wan Hai Lines, one of Asia’s largest container carriers. The vessel was en route from Shanghai to Mumbai, carrying electronics and consumer goods. Port authorities have implemented traffic control measures, diverting inbound and outbound ships to nearby anchorages.
What’s Next
-
Fire Containment: Navy tugs will continue to douse the blaze with foam and seawater until the heat is fully controlled.
-
Salvage Assessment: Once it’s safe, a marine survey team will board to evaluate structural damage and cargo loss.
-
Crew Welfare: Authorities have activated a support line for families of missing and injured sailors.
Stay tuned for live updates on the Wan Hai 503 fire as rescue efforts progress. Mariners and local vessels are advised to keep clear of the area and monitor NAVAREA warnings for changes in traffic zones.
