Capsized Indian Navy Frigate Righted in Mumbai Dock

The INS Betwa after capsizing, December 5, 2016.

US-based salvage company RESOLVE Marine Group has completed the salvage of the INS Betwa, the Indian Navy frigate that capsized inside a dock at a naval shipyard in Mumbai late last year.

The 3,800-tonne missile frigate rolled over on her port side during undocking at the Naval Dockyard (Mumbai) shipyard on December 5, 2016, killing two and injuring 14 others.

RESOLVE was contracted to conduct an immediate dive survey and then to stabilize, block and support the vessel to allow the drydock to be fully dewatered.

Working alongside the Indian Navy, the RESOLVE-led crews inspected all compartments of the vessel, then proceeded to patch and repair all damages, and secure all openings.

With the engineering plan in place, salvage teams were able to complete repairs to the internal tanks as well as the side shell of the vessel. Then by systematically flooding and pumping compartments, the vessel was rolled upright and done so without the use of any external lifting mechanisms.
