Aadesh-class patrol vessel

"Aadesh"-class patrol vessels are a series of twenty fast patrol vessels (FPVs) built for the Indian Coast Guard by Cochin Shipyard Limitedat its shipyard in Kochi, Kerala. The ships have been designed by M/s Smart Engineering & Design Solutions (SEDS), Kochi.
Description.
These vessels have a length of 50 metres, a beam of 7.6 metres, and a draught of 1.6 metres with a design speed of over 33 knots. They are powered by Tognum supplied triple type 16V 4000 M90 engines with an output of 2,720 kW (3,648 bhp) at 2,100 rpm, coupled with ZF 7600 gearboxes and propelled by triple Rolls-Royce Kamewa 71S3np water jets. This enables the vessels to operate in shallow waters and offers higher speeds and better maneuverability than conventional propellers. The MTU 'Callosum' ship automation system provides an integrated solution for monitoring all ship's services that also incorporates fire detection and extinguishing systems. The navigation package was supplied by Northrop Grumman and includes multi-function displays, electronic chart display and information system (ECDIS), autopilot, magnetic compass, and the NAVIGAT 3000 fiber optic gyro-compass.
The vessels are equipped with a long-range gun and ultra-modern vessel control, navigation, and communication tools. They are capable of 7 days' continuous deployment at sea without replenishing supplies. These FPVs are small in size when compared to other large vessels that Cochin Shipyard has built. Extensive use of aluminium in the superstructure was madeto reduce weight, and Cochin Shipyard has developed special techniques to ensure high-quality welding and fabrication of aluminium structures. All the vessels delivered achieved speeds in excess of the contracted speed during sea trials and surpassed the expectations of the Indian Coast Guard with regard to the performance requirements.
The primary roles of the vessel include fisheries protection and monitoring, patrol within India's exclusive economic zone, coastal patrol, anti-smuggling, anti piracy, and search and rescue operations. The vessels have a secondary role of providing communication link and escorting convoys during hostilities and wartime.
