Comparison of offshore renewable technologies using a reliability-based simulation tool
The Operation and maintenance (O&M) of offshore renewables has been highlighted as one of the most difficult aspects to evaluate for the viability of marine energy farms. In this work the authors compare two case studies, with particular regard to reliability and availability improvement, examining two of the most significant categories in offshore energy conversion: offshore wind and wave energy converters. A new decision support model for simulating the operating life of marine renewables is presented. Results provided in terms of costs, reliability, energy production and availability are analysed and compared for two simulated offshore farms composed of offshore wind turbines and wave energy converters respectively. The ultimate aim of the paper is to show the type of information the developed O&M simulation tool can supply in order to assist farm owners and operators in the decision-making process of cost reduction related to the deployment of marine energy farms.
