Abstract
This report gives an overview of existing commercial as well as non-commercial decision support models and their main characteristics. It focuses mainly on operation and maintenance, offshore logistics, power production and total project cost. These models were found through an extensive search of published literature, research organizations, research projects, and consulting companies. The search detected 49 models that address parts of the life cycle or the whole life cycle of an offshore wind farm. However, the majority of the models are not public available or commercial models. Thus, there is a need to develop a general model concept for NOWITECH, based on the information found in the reviewed models.
