heal.abstract	An integrated design and multiobjective optimization approach to ship design is herein presented. It integrates methods and software tools for the simultaneous evaluation of key measures of merit in the early phase of ship design. The implemented approach is herein applied to the design of an Aframax tanker for which a variety of parameters related to payload, steel weight, strength, oil outflow, stability and hydrodynamics were considered within an integrated multiobjective design and optimization procedure. Required Freight Rates (RFR), Oil Outflow Index (OOI), Energy Efficiency Design Index (EEDI) and maximum speed for given main engine margins were determined so as to rank design alternatives. Formal exploration and exploitation strategies were utilized to investigate the design space and, subsequently, advance competing design proposals into certain directions such as maximum energy efficiency, attainable speed and environmental protection in case of accidents. The paper focuses on the integration of design methods, of related software tools and optimization, utilizing the design of a tanker as an elaborated demonstration example to illustrate the holistic view of the adopted approach. ©2011: The Royal Institution of Naval Architects.	en
