''Aadesh-''Class Fast Patrol Vessels (FPV) are a series of 20 patrol boats being built by Cochin Shipyard Limited for the Indian Coast Guard at its shipyard located at 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, beam of 7.6 metres and 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) @ 2,100 rpm, coupled with ZF 7600 gearboxes and propelled by triple Rolls-Royce Kamewa 71S3np water jets. This enables vessels to operate in shallow waters and offer higher speeds and better manoeuvrability than conventional propellers. 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 is being supplied by Northrop Grumman's Sperry Marine business unit which includes VisionMaster™ Total Watch™ 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. The vessels are capable of 7 days continuous deployment at sea without replenishing. These FPVs are small in size when compared to the large vessels that Cochin Shipyard has built. But designing and building these vessels posed challenges to the yard as these are extremely weight sensitive vessels. Hence extensive use of aluminium in the super-structure has been made and Cochin Shipyard has developed special techniques to ensure high quality welding and fabrication of Aluminium structures. The shipyard has achieved excellent weight control on these ships right through the build process which resulted in difference between the design weight and actual weight of only about 2 metric tons i.e. a difference of less that 1%. All the vessels delivered have achieved speeds in excess of the contracted speed during sea trials and surpassed the expectations of Indian Coast Guard with regard to the performance requirements. The primary role of the vessel include fisheries protection and monitoring, patrol within exclusive economic zone (EEZ), coastal patrol, and 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 war time. As per contract worth INR 1500 crore signed in Delhi on 20 October 2010 between Preethi Sudan, joint secretary in the Defence Ministry and Bejoy Bhaskar, Deputy General Manager, Cochin Shipyard Limited, the first ship is to be delivered within 20 months and one every three months thereafter. The vessels are being built under the dual classification requirements of American Bureau of Shipping and Indian Register of Shipping. The total outfitting package has been designed,supplied and installed by M/s Sushmalethe Marinetec Private Limited, Mumbai. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aadesh Class Fast Patrol Vessel」の詳細全文を読む スポンサード リンク
