Abstract

La présente invention se rapporte à un trimaran. Le trimaran présente une structure différente à partir d'un trimaran existant dans lequel trois coques minces partagent un pont principal. Dans le trimaran, une structure de système de tige spatiale (1) remplace les coques partielles entre le pont principal et une ligne d'eau du trimaran existant, de telle sorte que le volume des coques partielles est réduit, et la force d'impact des ondes sur les coques partielles est réduite. Le trimaran présente une meilleure résistance aux vagues. Le trimaran peut être divisé en parties supérieure, intermédiaire et inférieure qui sont reliées. La partie supérieure comprend des installations de couche supérieure, et les installations de couche supérieure se réfèrent à des installations montées sur la partie supérieure du trimaran, telles qu'une plate-forme (4), une cabine, un salon et un dispositif de levage. La partie intermédiaire est la structure de système de tige spatiale (1) constituée de tiges. La partie inférieure comprend trois coques minces. La structure de système de tige spatiale (1) peut résister à des moments de flexion et de torsion générés par le trimaran en utilisation. Une enceinte (6) est en communication entre la coque intermédiaire (2) et les installations de couche supérieure dans le trimaran. Le trimaran de la présente invention peut en outre être conçu pour être un trimaran à coque immergée.
