海上风电场的运行和维护变得越来越具有挑战性，因为风电场正在远离海岸进行调试。天气窗口更难导航，导致涡轮机停机时间更长。X-Rotor海上风力涡轮机概念直接解决了这些O&M挑战，除其他优点外，消除了对传统上导致高故障率，维修时间和停机时间的组件的要求，并将重型和昂贵的机械放置在更接近海平面的地方。该涡轮机还受益于具有模块化小转子，该模块化小转子可以在陆上快速更换和修理，并且当模块化转子中存在故障时能够以减小的容量运行。本文介绍了StrathX-OM OpEx模型。该模型对OpEx建模进行了更改，允许对由激进的X-Rotor风力涡轮机组成的风电场的运营和维护成本进行全面分析，并随着技术的进步灵活地处理不断变化的设计。对距离海岸100 km的风电场的寿命期运行和维护成本的计算表明，对于既定设计，X转子的运行和维护成本低于传统HAWT。对X转子的估计故障率进行了灵敏度研究。这表明，即使故障率被大大高估，X-Rotor在当今市场上仍具有竞争力。
O&M of an offshore wind farm is becoming increasingly challenging as farms are being commissioned further from shore. Weather windows are more difficult to navigate leading to longer downtime for turbines. The X-Rotor offshore wind turbine concept directly tackles these O&M challenges by, amongst other advantages, removing the requirements for components that have traditionally contributed high failure rates, repair times and downtimes, and by placing the heavy and expensive machinery closer to sea level. The turbine also benefits from having modular small rotors that can be quickly replaced and repaired onshore, and being able to operate at reduced capacity when there are failures in the modular rotors. This paper presents the StrathX-OM OpEx model. This model features changes to OpEx modelling that will allow for comprehensive analysis of the operations and maintenance costs for a wind farm made up of radical X-Rotor wind turbines with the flexibility to handle changing designs as the technology progresses. The calculation of lifetime O&M costs for a wind farm 100 km from shore showed that the X-Rotor has lower O&M costs than conventional HAWTs for an established design. A sensitivity study on the estimated failure rates of X-Rotor is also presented. This shows that even with significantly over-estimated failure rates the X-Rotor would still be competitive in today's market.
