AVARNE CLASS | PATROL VESSEL
Length: 80 meters
Width: 21.1 meters
Draft: 3.2 meters
Displacement: 4,000 tons
The Avarne Class patrol vessel is a long range, high speed patrol ship. The ship is deployed in Navy service for border patrol and green-water tasks; but it can also be repurposed for military or civil use for command and control, hydrographic surveys, surveillance, search and rescue, force transportation, amphibious operations and humanitarian support missions.
The compact and low cost platform will meets the requirements of the NH Navy to maintain peace and stability in our coastal zones.
The multirole vessel incorporates a trimaran hull made from aluminium alloy. The flexible design uses patented trimaran technology, delivering fuel efficiency and improved passenger comfort, permitting long-term operations - although a usual operational sailing time is two week's sailing.
The unique trimaran design comprises three hulls, including one long slender hull in the centre and two side supporting hulls. The three-hulled configuration delivers higher performance than the traditional high speed boat, employing either catamaran (two-hulls) or monohull (one hull) designs.
This trimaran hull arrangement provides good sea keeping and copious space for a variety of missions. Proven in both commercial and defence operation, the trimaran offers high speeds and slower roll.
The ship can maintain higher speeds in waves and provide greater comfort for passengers and crew when in the same sea conditions. The onboard open architecture systems network provides interoperability to the users.
The multirole vessel has an overall length of 80m, moulded beam of 21.1m, moulded depth of 6.7m and a hull draft of 3.2m. The dead-weight of the vessel is 400t. The ship complements a crew of 35, including the helicopter crew and air wing.
The multirole vessel features three decks.
The main gun fitted forward is the 35mm Millennium Gun. The gun can protect the hostile ship from small, fast and agile surface threats, and is an effective offensive weapon. The ship is provided with gun mounts for four .50 calibre general purpose machine guns.
The multirole vessel is powered by three MTU 20V 4000 diesel engines driving three fixed pitch propellers. Each engine delivers an output of 4,300kW at 2,170rpm. The propulsion system has a maximum speed of 26kt and a range of 4,500nm at 12kt. The ship has a maximal endurance of 28 days.
The Avarne Class Vessels are multi-crewed. This allows for short sailing times for individual crews, but allows the ship to keep out to sea for longer periods. Typically a squadron of four patrol boats will have three vessels at sea, with one vessel in a two-week maintenance period. There are a total of seven crews, with one assisting maintenance and performing other duties while three are at port and three at sea.
