摘要：Ship hull form is the outer part of a ship hull that is designed to satisfy ship owners requirement like ship operating speeds, fuel efficiency, course and stability. Analytical method is used to optimize and improve on the hydrodynamic performance in regular sea condition of 135-degree sea and 180-degree sea at 4m wave height to achieve good sea-keeping conditions, crew comfortability, manoeuvrability, good fuel consumption at the speed of 0,5,10,15,20,23 and 25 knots. When a platform supply vessel moves forward through the open sea, pressure sea wave builds up at the bow of the ship which increases the sea wave height andconstantly flows backwards to the aft side of the hull.This increases the drag of the vessel which results in the movement of the ship,thus, increasing the fuel consumption and resistance of the vessel. To overcome these issues bulbous bow is then designed using SACS modeler to adjust and drag the hull NURB surfaces to achieve a well-defined smooth hull form giving consideration to the main dimensions of the parent ship BOURBON HELENA a platform supply vessel (PSV). Comparing the initial design ship hull form Response Amplitude Operators (RAOs) responses and the resistance values of 1585,1348,1155,990,847,771,724 (for 180-degree sea) and 1482,1332,1208,1096,993,934,897 (for 135-degree sea) to the optimised designed hull form values of 472,429,395,365,338,324,315 (for 135-degree sea) and 478,422,379,341,309,291,280 (for 180-degree sea). it was observed that, there was significant reduction in the optimised hull form results as well as the vessel pitching motion and as a result of good forward buoyancy of the ship. The effective powers for both hull form was estimated by MATLAB using the sacs resistance results as the input values.
