Design Procedure and Mathematical Models in the Concept Design of Tankers and Bulk Carriers

Paper presents design procedures and mathematical models applicable in initial design of merchant ships with high block coeffi cient. Special attention has been paid to two dominant ship`s groups: tankers and bulk carriers. Presented design procedure is common for both groups and it can be applied using various application techniques: from the simplest handy methods to the most sophisticated optimization methods and techniques. Presented mathematical model includes optimization of main ship characteristics as well as optimization of commertial effects of newbuildings. Mathematical models are based on designer´s long-time work experience. Large number of data has been derived from more than 150 executed designs and more than 40 ships built in Shipyard Brodosplit. Recommendations for execution of design are shown in number of pictures and diagrams. Presented design procedure and mathematical models have been applied in the multiattribute decision support optimization programme developed in Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb
