碩士 === 國立臺灣海洋大學 === 系統工程暨造船學系 === 100 === This study is to analyze the design of the structure of the high-speed catamarans subject to different ship speed and significant wave height that produce the wave impact pressure on the cross structure. Analysis has been made by using real ship parameters to identify the most suitable structural design under various conditions. Calculations have been carried out and discussion made for a range of cases by the use of ANSYS software. It examines the use of the finite element analysis as a method of a real case for “Ocean LaLa” forward cross-structural damage investigation in accordance with the regulatory compliance of the ship classification societies DNV. Because the bow structure difference in actual construction and design, so priority to discussing the intensity of the two difference structures, and the load structure in accordance with the actual construction of structures to be improved and to assess the strength improvement effect. Finally, this three structures according to the 15, 17.5, 20, 22.5, 25, five design speed in knots with the 2.5, 3, 3.5, 4, 4.5, 5, six significant wave height in meters were compared, obtained in the original design and improved structure only in cases 15,17.5 knots 2.5 meters significant wave structure is not damaged.
