INS Betwa
Mumbai | India
The 3,800-tonne Indian Navy missile frigate INS Betwa capsized on her port side due to a loss of stability while undocking.Resolve Marine was contracted to conduct an immediate dive survey, then to stabilize, block and support the vessel to allow the drydock to be fully dewatered. Working alongside the Indian Navy, crews inspected all compartments of the vessel, then proceeded to patch and repair all damages, and secure all openings.
With a sophisticated engineering plan in place, salvage teams were able to complete extensive repairs to the internal tanks as well as the side shell of the vessel. By systematically flooding and pumping compartments, the vessel was rolled upright and done so without the use of any external lifting force.
The entire salvage operation was concluded in less than two months and required complex hydrodynamic calculations and the use of intricate measuring and monitoring systems.
