NOWIcob – A Tool for Reducing the Maintenance Costs of Offshore Wind Farms

摘要: Abstract It is essential to implement cost-effective operation and maintenance concepts strategies achieve a significant reduction of cost energy from offshore wind farms. A decision support tool (Norwegian benefit model – NOWIcob) was developed that simulates the operational phase an farm with all activities costs. This can be used understand sensitivities costs due changes in logistic strategy, helps choose optimized strategy for specific farm. The based on time-sequential event-based Monte Carlo technique takes into consideration weather uncertainty other relevant aspects Different vessel accessing time-based, condition-based corrective tasks simulated. delivers results form availability, life cycle profit, cost, produced electricity performance criteria. main characteristics underlying scientific models will described. In addition, application NOWIcob demonstrated theoretical case far-offshore using mothership/daughter ship concept, benefits such highlighted.
