NEW DELHI: India’s Coast Guard and Navy were struggling on Tuesday to extinguish a fire on a Singapore-flagged cargo ship that exploded in the Arabian Sea, triggering an alarm over its load of 100 tonnes of bunker oil.
The MV Wan Hai 503, en route to Mumbai from Sri Lanka, reported an internal container explosion on Monday, which triggered a major fire on board as the vessel approached the coast of the southern state of Kerala.
The Indian Coast Guard said the situation was “critical” as its ships engaged in an overnight operation to douse the flames and rescue 22 members of the vessel’s crew.
Four crew remain missing. Two of them are from Thailand, one from Indonesia and one from Myanmar, according to Singapore’s Maritime and Port Authority, which sent a team to assist the Indian rescuers.
Containers falling from the ship were reported drifting between Kerala’s Kozhikode and Kochi, triggering an alert by the Indian National Centre for Ocean Information Services over a potential spill of what it identified as 100 tonnes of bunker oil.
Bunker oil is a thick, heavy and viscous fuel used to power large ships, especially cargo vessels and tankers. It is one of the dirtiest and most polluting fuels.
It contains sulfur, heavy metals and carcinogens. If spilled, it is difficult to clean up and may persist for months or years in the marine environment, suffocating coral reefs and killing fish and seabirds.
“Caution is advised about a few containers beaching between Kozhikode and Kochi,” the INCOIS said in a notification, adding that there was an “estimated 70-80 percent probability” that the containers that went overboard from the MV Wan Hai 503 might drift south-southeastwards from the accident location for the next three days.
The incident took place just two weeks after a Liberian-flagged vessel carrying hazardous cargo sank off Kerala’s coast.
The vessel went down with cargo containing calcium carbide and more than 84 metric tonnes of diesel, and 367 metric tonnes of furnace oil.
Diesel and furnace oil are both classified as marine pollutants that are toxic to marine life and can contaminate coastal ecosystems.
