This chapter 7 describes a decision support tool that was designed and developed for the MERMAID project (EU-FP7), which has already indicated in this book developed concepts for next-generation offshore platforms for multi-use of ocean space for energy extraction, aquaculture and platform-related transport. Specifically, it evaluated the potential and challenges of building multi-use offshore platforms (MUOPs). The MERMAID project considers four offshore study sites for multi-use offshore platforms, Atlantic Ocean site, Wadden -North Sea site, Baltic sea site, and Mediterranean Sea site. Each site is considered in terms of its available resources and unique features. This tool was part of the framework for assessing the socio-economic impact of MUOPs, and as such, utilized web and data analytics state of the art technologies in order to provide researchers with a framework for evaluating feasibility and potential of each MUOP's proposed design and location.
