A method is presented by which the wave wake generated by a ship may be repeatedly calculated very rapidly. The method is based on linear thin-ship theory, using the idea of elemental tent functions as building blocks to represent the hull, which have previously been applied in the context of resistance minimization. This approach allows much of the calculation to be carried out in advance, with the results stored in a database. Issues of convergence, accuracy, and storage strategy are discussed. In order to demonstrate the application of the approach to preliminary design optimization, an illustrative study is carried out in which hull forms for monohull and catamaran vessels are optimized in the sense of minimizing the maximal wave height along a series of longitudinal cuts. The effect of the transverse location of the cuts on the resulting hull forms is found to be quite substantial, especially for the catamarans; the performance of the vessels optimized to reduce wave height at one transverse location may be quite suboptimal at another location, illustrating the difficulty of choosing an appropriate specification for low-wash vessels.

Ice Resistance

An optimum procedure of hull form design for ice ship going “Double Acting Tanker” is introduced. The procedure orderly consist of hull form design, analyses of performance of a ship in open water and ice condition, maneuverability performance, ice loading effect on propeller and torsional shaft, and economical and environmental societies. In the present study, only two topics are mainly discussed, which are hull form design and then continued with performance analysis in ice condition and open water. For the hull form design the objective parameter are considered as follows; stem and the stern angles, upper and lower fore bulbous angles, entrance angles, and spreading angles. All those angles are investigated for both full loaded and ballast condition in ahead and astern. Special concern is needed for stern part due to existing propeller effect on ice breaking performance. The hull form is firstly investigated without installation of propeller to avoid the effect of pressure from propeller and then continued by installation of propeller to find the optimum propeller design and propeller immersion. Research in ice condition is compromised with open water. The optimum hull form, propeller design and propeller immersion is when the hull form gives better performance for both open water and ice condition. The selected hull form then is compared with existing DAT tanker “Tempera”.
