The ships have been designed by Rolls-Royce Holdings and have the type number UT 517. The vessels are 94 meters long, with a displacement of 3300 tons and maximum draught of 4.5 meters. The vessels are designed to attain speed of 20.5 knots. They have an endurance of 6500 nautical miles at economical speed and can stay at sea for 20 days. The ships are crewed by 10 officers and 100 sailors specialized in various streams.
Each vessel is fitted with two Rolls-Royce supplied Bergen B32 diesel engines, two Kamewa Ulstein propeller plants, an Ulstein Aquamaster thruster, Tenfjord steering gear, an Ulstein rudder, Rauma Brattvaag deck machinery, Ulstein automation system and switchboards and Intering anti-roll stabilization.Its anti roll stabilization system is the first to be incorporated on a coast guard vessel built in India. Other major features of vessels are Integrated Platform Management System (IPMS) and its Dynamic Positioning System enabling the vessel to be maneuvered in restricted areas with precision.
The equipment on board is used for containment, recovery, separation and dispersal of pollutants. High tech control systems enable simultaneous tasks to be performed by a single operator. The vessel is fitted with latest pollution control equipment including two rigid sweeping arms enabling it to contain oil spill whilst in motion. An advanced software would assist in predicting the spread of the complex oil spill pattern. The vessel is designed to recover the lightest to the most viscous oil at the rate of 300 tons per hour. The contaminated water can be pumped on board and analysed in a laboratory. The oil can then be separated and held in storage tanks of 300 tonnes capacity or 1000 tonnes in inflatable barges which can be towed behind the vessel to free up deck space. The vessel is also equipped with fire fighting and salvage systems.
The secondary role includes peacetime patrolling, firefighting and salvage. For maritime law enforcement, EEZ surveillance, anti smuggling, fishery protection, search & rescue and high speed interdiction it is equipped with CRN 91 Naval Gun, light helicopter, five High Speed Boats and four Water Scooters. An Infra Red Surveillance System is also installed on-board providing additional capability for the ship's crew to detect targets in the night. The vessels are also equipped with fire fighting and salvage systems.
