In August 1998, the UK Ministry of Defence awarded a contract to Vosper Thornycroft to construct the trimaran, at a cost of £13.5m RV Triton was launched in May 2000 and delivered in August 2000. Triton then began a two-year risk reduction trials programme for the UK MoD and the US Department of Defense. The vessel's three parallel hulls are reflected in her name which refers to the maritime god Triton who carried the three-pronged spear, the trident. The outriggers are thinner and much shorter than the dominant central hull.
Operational history
DERA and QinetiQ
Triton was designed as a demonstrator to prove that the trimaran concept would work successfully in a large warship. Following her launch in 2000, the ship began an extensive series of trials in 2001, which covered general ship handling, performance, sea-keeping behaviour, but also areas more specific to its design for which the Royal Navy had no experience. For example, a series of docking manoeuvres were undertaken by the pilot boats of HMNB Portsmouth to determine the problems of docking a large trimaran, and the ship underwent underway replenishment alongside and the tanker RFA Brambleleaf to ascertain the characteristics of a trimaran and a monohull replenishing at the same time. Triton also undertook the first helicopter take off and landing on a trimaran.
In January 2005, Triton was sold to Gardline Marine Sciences, a UK company based in Great Yarmouth, Norfolk. Triton was used for hydrographic survey work for the civil hydrography programme on behalf of the Maritime and Coastguard Agency. The vessel was fitted with a sensor suite which includes the Kongsberg Simrad EM1002 multibeam echo-sounder, a GPS attitude / heading system, surface navigation and ultra-short baseline sub-surface acoustic tracking system, Gardline Voyager5 integrated survey system and Caris post-processing system. The vessel was enhanced by Gardline by installing a bowthrust unit, additional accommodation and survey equipment facilities. In 2009, two new MTU engines were fitted; MTU 16v 4000 M40B. Output 2,080kW each.
Australian Customs
In December 2006, Gardline contracted Triton to the Australian Customs and Border Protection Service to patrol Australia's northern waters as one of the service's fleet of patrol vessels. Australian Customs Vessel Triton has been fitted with two.50 calibreheavy machine guns and carries up to 28 armed customs officers. The vessel is also equipped with two 7.3m high-speed rigid hull inflatable boats. The ship arrived from the UK in mid-January 2007 and started operations immediately. Austere accommodation is provided for 100 embarked persons in addition to conventional accommodation for 45.
