The core innovation in the IDEAS project will be the development of methodologies and decision support tools that integrate the three levels of maritime system design; ship, fleet and value chain design. These solutions will involve already established st ate-of-the-art methods and tools for analysis on the different levels individually, e.g. the TurboRouter tool (MARINTEK) for fleet analysis and the Pre-Contract tool (DNV) for ship design decision support. This project should focus on interfaces between a nd integration of such existing tool, so that the outcome will be a highly innovative overarching solution that provides totally new possibilities for optimalisation of the total maritime transport system.
