dc.description.abstractThis master thesis is carried out at TTS Marine AB in Gothenburg; a company specialized in design, engineering and construction of large complex and moveable steel structures for large ships, such as PCTC, RORO and ROPAX. Typical products is equipment and solutions of rolling goods, i.e. large off and on loading ramps, car decks, hoist able decks, quarter stern ramps, etc. The procedure for developing and designing a new product or steel structure is first to create a JavaScript that combined with the software program GeniE generates a computer model. Due to the fact that no products are identical, these scripts need to be redeveloped and rewritten for each new product is designed, a time consuming and costly process. Utilization of man hours and the duration of the engineering phase is of great importance in the time aspect of weight optimization of the steel structure, this is particularly important in designing and construction of floating vessels. Reduced weight reduces fuel consumption, increases cargo capacity and allows for increased speed, factors that have an impact on company revenue. Calculations related to weight optimization of TTS products is currently performed mainly manually, the result and accuracy is of high quality due to extensive experience, references and large knowledge. By using a developed and sophisticated tailor made software system may man hours and duration be decreased and at the same time gain traceability and transferable documentation This thesis has two purposes. The first is the modularization of a number of structures. This is achieved by developing a JavaScript that with the right input values can generate a number of different products, (i.e. ramps) thus reducing man hours and duration for weight optimization calculations. The second purpose is to define an optimizing method that can be implemented with GeniE. The optimization method is foreseen to be a part of the basis for the planned development of a new software program that automatically will optimize the steel structure in a ramp. A large number of existing ramps has been studied in order to identify components and features that are common in the different ramps. These features are compiled and described and an explanation of how the script is built is included in the report. The final script has been evaluated and tested by engineers with extensive experience to calculate structures by using the software program GeniE. In preparation for the optimization calculations, a number of different variable parameters in the structure have been reviewed, variables not applicable for optimization has been precluded. A study of optimizing methods has been undertaken and a suitable method is identified. An optimizing algorithm for the structure has been developed.
