Taiwan is a maritime transportation hub in East Asia. Along with the opening of cross-strait direct flights, the flying time between Taiwan and the coastal cities of Mainland China has shortened significantly, which allows the forming a one-day living circle across the Taiwan Strait. Furthermore, the introduction of new generation high-speed passenger-cargo craft by shipping carriers has changed the traditional maritime transportation mode of passengers and cargos between both sides of the Taiwan Strait and greatly reduced the shipping time at sea.
This study focused mainly on how high speed craft achieve stability during high-speed navigation through vertical movement and balanced action generated by T-foils equipped at the bow and the trim tabs equipped at the stern, which not only help enhance navigation safety, but also lower the risk of cargo and vehicle movement, reduce violent shaking of ship, increase the level of passenger comfort, and improve the operational efficiency of the ship, so as to achieve the operational tasks in a fast, accurate and stable manner.
In this study uses the actual sea trial data of the shipyard, and calculates the stability calculation formula of the ship inspection institution, and then analyzes the operation with HydroSTAR software an aim to explore the effect of vertical movement on the stability and comfort. The results of the research show that, under weather constraints and wave height conditions, the vertical acceleration obtained will be smaller when the position of the longitudinal centre of gravity (LCG) of a ship moves toward the bow and larger when the position of the LCG moves toward the stern. In case of trim by bow, the vertical acceleration obtained is slightly smaller than that obtained under the condition of trim by stern. As LCG moves on the same horizontal plane, it gives rise to different heeling angles between the positions of LCG and the overlapped transverse ribs. The differences among different vertical accelerations can be found from the measurement of the variances of different angles by utilizing the stability calculation formula of the survey authorities. This study has established a set of operational management model which can be provided to the industry and relevant units for reference.
