ABSTRACT: The objective of this work is to employ a conceptual design framework in designing a new bulk carrier vessel by satisfying all constraints related to the shipyard constructional limitation and service life exploration factors in minimizing the cost or other design or operational factors. A developed interactive intelligent conceptual design framework “Expert”, which can be applied in designing commercial ships is employed here. To support the conceptual design environment, the framework accommodates the existing design experience and knowledge into mathematical tools that can be operated by computer systems. Different mathematical models are used in identifying the main dimensions of ship, ship hull form, mass and volume distributions, general arrangement, ship hull structures and equipment; propulsion complex; freeboard requirements; stability; sea-keeping; manoeuvrability etc. These models are operating in compliment of the requirements of the Classification Societies, including the shipyard construction and navigation restrictions and cost models for a ship construction and operation during the service life.
