50m Fast Patrol Vessel (FPV), India
The 50m-long Fast Patrol Vessels (FPVs) are being built by Cochin Shipyard, for the Indian Coast Guard. The Coast Guard's plan includes putting 20 FPVs into service between 2013 and 2017. The vessels will conduct operations in Indian coastal waters and adjacent island territories.
The vessels are deployed in missions such as anti-smuggling, anti-piracy, fisheries protection, search and rescue (SAR), exclusive economic zone (EEZ) surveillance, and coastal patrol. The FPVs can also be used as communication and escort platforms during hostile and wartime conditions.
The Indian Coast Guard placed an INR15bn ($338m) worth contract with Cochin Shipyard for the construction of 20 FPVs in October 2010. The first and second offshore patrol vessels (OPVs) in the series, ICGS Aadesh (236) and ICGS Abheek (237), were launched in January 2013 and March 2013 respectively. The Abheek was delivered in October 2013. The first two vessels were commissioned into the Indian Coast Guard in December 2013.
The third vessel, ICGS Abhinav (238), was launched in May 2013, and was delivered and commissioned in January 2014. The fourth vessel in the series, Abhiraj (239), was launched in September 2013 and delivered to the Indian Coast Guard in March 2014. The vessel is based at the Coast Guard station in Tuticorin. The fifth and sixth patrol vessels were launched in November 2013.
Design and features of the FPVs built by Cochin Shipyard
The superstructure of the mono-hull OPVs is made of marine grade aluminium for achieving weight reductions. Modern welding and fabrication methods were employed in the construction to produce a high quality product. The modern weaponry and sophisticated communication and navigational systems aboard the vessel enable multi-role coastal missions.
The vessels meet the dual classification requirements of American Bureau of Shipping (ABS) and Indian Register of Shipping (IRS). Each FPV has a length of 50m, beam of 7.6m and draft of 4.65m. The displacement of the vessel is 290t and typical crew capacity is 39.
Command and control
Northrop Grumman, through its Indian reseller Marine Electricals, received a contract in November 2012 to deliver modern shipboard navigation systems for the 20 fast patrol vessels being built at Cochin Shipyard.
The patrol vessels boast an integrated bridge management system and integrated machinery control system (IMCS). The OPVs are equipped with VisionMaster Total Watch multifunction displays (MFDs), electronic chart display and information system (ECDIS), auto-pilot, magnetic compass and NAVIGAT 3000 fibre optic gyrocompass supplied by Northrop Grumman's Sperry Marine.
Naval gun system aboard India's fast patrol vessels
The main weapon fitted on the forward bow deck of the FPV is a gyro-stabilised 30mm naval gun system. The integrated gun mount aboard the vessel is supported by an indigenously built fire control system (FCS).
Propulsion for the 50m FPVs
The OPV is powered by three Tognum 16V 4000 M90 engines driving three Rolls-Royce Kamewa 71S3np water jets. Each engine generates a maximum power output of 2,720kW. The propulsion system also integrates ZF7600 gearboxes, allows operation in shallow waters, and provides higher speeds and superior manoeuvrability when compared with conventional propellers.
Tognum was awarded two contracts in 2009 to deliver engines and automation systems for the vessels. A follow-on order was also placed in April 2011 for the supply of engines and automation systems.
Rolls-Royce received a contract from Cochin Shipyard in September 2011 to deliver 60 water jets and associated equipment for the 20 OPVs.
The OPVs have an endurance of 1,500nmi at economical speed of 13kt, while the maximum speed is 33kt.
