Trimaran Demonstrator Project

      1/24/2000

Trimaran Demonstrator Project

The UK Defence Evaluation & Research Agency (DERA) Trimaran Demonstrator, R.V. TRITON, is currently being built at Vosper Thornycroft’s Southampton yard. In conjunction with DERA and Vosper Thornycroft, the Royal Institution of Naval Architects will host a two day international conference about the project, including a unique opportunity for delegates to view the vessel itself (Southampton, April 18th & 19th, 2000). The ship will be used to test the suitability of the Trimaran hullform for future surface warships, and trials will include seakeeping, powering and structural analyses.

The Trimaran hull form offers several advantages over conventional monohull designs including:

  • hull resistance, narrow centre hull reduces hull resistance and therefore power required (typically 18% less installed power for same top speed in an escort sized vessel required to achieve 28 knots)
  • improved seakeeping performance at higher speeds, operational in higher sea states
  • greater fuel economy
  • helicopter operation, larger deck and hangers, improved stability and reduced motion
  • increased directional stability
  • top weight growth margins are greater
  • wide range of propulsion options
  • potential for reductions in radar cross section and infrared signatures

The technologies being developed and proven using the Trimaran Demonstrator research vessel will be used to feed into future platform designs opening up the possibility of a complete Trimaran fleet.
