Simulation model for operation and maintenance strategy of floating wave energy converters - analysis of fatigue, wear, and influence of biofouling for effective and profitable energy harvesting
Research Project, 2016 – 2018

The project is a continuation of the project “OEC-durability analysis of cables and moorings used in systems for harvesting of renewable ocean energy” where a “holistic” simulation model of a floating wave energy converter was developed. The aim is to develop the model’s modules to increase the precision in simulation results in order to propose reliable operational and maintenance strategies. By collaboration with technology companies in the area, more cost-effective and profitable energy production will be achieved. Examples of specific aims: (i) increase the reliability of the model by a halving of the model uncertainty and quantification of the total prediction uncertainty, (ii) development of a detailed cable model for analysis of mechanical life and electrical conductivity, (iii) present a methodology for accurate operation and maintenance strategy, (iv) validation of the simulation model against new model tests, (v) compare results of model tests and field trials at full scale.
