History

In March 2004, the Indian Coast Guard placed an order for a single Advanced Offshore Patrol Vessel at a cost of ₹228.14 crore (equivalent to ₹650 crore or US$91 million in 2019). In August 2005, a repeat order was placed at the same cost for a similar vessel under options clause of the original contract.[6][7][8]

Description

Sankalp-class vessels have an overall length of 105 metres, a 12.9 metre beam and a draught of 3.6 metres. They are powered by two SEMT Pielstick 20 PA6B STC diesel engines rated at a combined 20,900 PS or 15,400 kW, each driving a Wärtsilä WCP 5C10 controllable-pitch propeller.[1][9] They have a top speed of 24 knots and a range of 6,500 nautical miles at 12 knots. Sankalp class is armed with two 30 mm CRN-91 naval guns controlled by a fire control system and two 12.7 mm "Prahari" machine guns.[10] They are equipped with external firefighting systems, an integrated bridge system and an integrated machinery control system. Sankalp-class ships can carry five high-speed boats capable of search and rescue, interception and pollution control missions.[11] The vessels of this class have been classified by both Indian Register of Shipping and American Bureau of Shipping.[12]

Operational history

In August 2011, ICGS Sankalp participated in a mission to control an oil spill off the coast of Mumbai.[13] In September 2012, Sankalp was tasked to fight a fire onboard MV Amsterdam Bridge.[14] Sankalp has undertaken goodwill visits to Malaysia, Australia, Indonesia, Qatar and Oman.[15][16][17][18]

In December 2013, a CRN-91 naval gun on ICGS Samrat was accidentally triggered as it was being repaired, partly damaging the Western Naval Command headquarters building in Mumbai.[19] In June 2015, ICGS Samrat participated in a disaster relief mission to rescue 20 crew members of MV Jindal Kamakshi.[20] In December 2017, ICGS Samrat rescued 72 fishermen in distress off the coast of Kerala.[21]
