The Efficient Design Process Of A Bulk Carrier

This dissertation focuses on the systematic design process of a dry bulk carrier. In this design process, the approach to achieve an appropriate hull design is done through a number of stages. The initial stage is the presentation of the design problem that states the shipowner's requirements on the desired bulk carrier. In the second stage the main dimensions are determined by using the sample of data of built bulk ships and empirical formulas. Hull modeling is done in the third stage in which the CAD skills are applied. The hull subdivision arrangement is the fourth stage in which the classifications rules are applied. Modelling and calibration of tanks and cargo holds is performed in the fifth stage. By means of the Maxsurf' s Hydromax program, the hydrostatics and intact stability of the design are assessed in the sixth stage. The IMO intact stability criteria are evaluated to find out the design' s compliance with the IMO intact stability requirements. In this stage the IMO grain stability requirements are also analysed by using two selected partial loading conditions. The last stage involves the calculation of resistance, power, and propeller data. In this stage the type of main engine is also selected and ship speed is finally calculated. The Maxsurf's Hullspeed program and Bp-delta diagram are key tools for the tasks, together with the use of various empirical formulas. At the end of the design process it is intended to provide the hull design of a bulk carrier that suits the shipowner's requirements and also meets the IMO intact and grain stability requirements.
