MUMBAI: A day after Indian warship INS Betwa toppled at the naval dockyard here, killing two and injuring 22, the Indian Navy has yet to figure out a way to lift the ship and has called in foreign experts.

The Navy does not have a crane that can lift the 3,850-tonne frigate, which is floating in the dry dock since she keeled over on Monday. The cranes available with the Navy can lift only 100 tonne. Mazgaon Dock has a crane with a capacity of 300 tonne, but it can't be shifted out of the premises.

The salvage operation, which is a time-consuming process, will cost crores of rupees , said a naval officer.

Indian Navy's spokesperson in Mumbai, Commander Rahul Sinha, said the chief of naval staff Admiral Sunil Lanba visited the naval dockyard on Tuesday and was briefed about the incident. "He also met the injured sailors in naval hospital.

The Indian Navy shall set upright the ship and make her operational in the shortest possible time," said Sinha.
