MARCH 1, 2017 — Resolve Marine Group, Inc. and the Indian Navy have successfully rolled and righted the 3,800 t guided missile frigate INS Betwa.
Due to a loss of stability while undocking, the vessel capsized onto her port side in dry dock in Mumbai, killing two and injuring 14 others, on December 5, 2016.
Resolve 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 — without the use of any external lifting force.
