ABSTRACT
Within the last decades, goal based approaches have gained more and more popularity within the maritime industry. In contrast to prescriptive design approaches, goal based design approaches provide sufficient flexibility to evaluate the attained level of safety for novel ship designs, improve a ship’s level of safety beyond current rules and regulations, optimise a ship’s operability within the design constraints. While the application of goal based standards on safety relevant topics has been investigated in various research projects and is widely supported by authorities and classifications societies, its’ application on a ship’s operability has not been addressed in detail so far. This optimisation is an important task since the operational expenses (OPEX) and thus life cycle costs are directly related to a ship’s operability. Within the German research project MOPS, funded by the Federal Ministry of Economics and Technology, a design tool has been developed to investigate safety and operability related tasks in the context of the holistic design process. In this respect, ship motions are calculated by means of strip theory and incorporated into a multidimensional probability analysis. The results are presented on the example of a recent case study, taken from FSG’s data base.
