NEW DELHI: In a daring and complex operation, a Sea King 42C helicopter winched down a Marco officer on a merchant vessel on fire to arrest its drift towards the International Maritime Border Line with Bangladesh.

MV SSL Kolkata was abandoned by its 22-member crew on June 14 off the

at the mouth of the

after the fire engulfed 70 per cent of the ship carrying containerised cargo in the Bay of Bengal.

"The Marine Commando officer ascertained the conditions in the forward part of the ship and later called in the helicopter to lower on board three crew members of the ship," the Navy said in a statement.

"The team managed to drop the starboard anchor from the ship to prevent her from drifting any further. Thereafter, the team prepared the seamanship gear for the ship to be towed if required," the statement said.

The nature of the threat was evident from the explosion on board in the forenoon which restarted the fire.

The helicopter skillfully recovered all four members of the team and is returning base for turnaround, the statement added.

Earlier, Vice Admiral Karambir Singh, Flag Officer Commanding-in-Chief Eastern Naval Command, had directed that the ship's drift towards the

delta had to be stopped at all costs notwithstanding the high temperatures on board to avoid an ecological disaster should the ship capsize on the sandbanks causing pollution from oil on board.

Accordingly, a Sea King 42C helicopter and a Dornier aircraft were dispatched from Visakhapatnam with a core team comprising divers, Marcos, shipwrights and seamanship specialists to stage through the IAF airbase at Kalaikonda.

Ship Kadmat, which was exercising in the Bay of Bengal on June 15, was also directed to proceed and arrived on site at first light this morning to augment the onsite support wherein the

ships were standing by.

The operation this morning has successfully managed to arrest further drift of the ship to enable salvage operations.
