运营和维护（O & M）在海上风电场的寿命期间占费用的很大一部分。与陆上风电相比，由于使用专门的船舶，较短的天气窗口和具有挑战性的环境条件，O & M成本增加。此外，故障频率的增加、停机时间的延长和有限的可访问性在O & M任务的规划阶段造成了不确定性。为了降低发电成本并提高海上风电行业与其他替代能源行业的竞争力，必须将用于O & M任务的船队成本保持在最低水平，同时提供足够的支持以维持发电。为了解决这些问题，本文的重点是提供决策支持的选择船员转移船（CTV）船队的海上风电场的维护操作。这是通过分析环境条件、调查故障和评估船舶操作来实现的。开发的方法和分析使运营商能够决定CTV的规格，这将带来最佳的财务效益，同时考虑到海上风电场发电的增强以及总O & M成本的最小化。
Operation and Maintenance (O&M) contributes a significant share of the expenses during the lifetime of offshore wind farms. When compared to onshore wind, O&M costs are increased, due to the use of specialised vessels, shorter weather windows and challenging environmental conditions. Furthermore, increased frequency of failures, longer downtime and limited accessibility create uncertainties in the planning stage of the O&M tasks. In order to decrease the cost of power generation and increase the competitiveness of offshore wind industry against other alternative energy sectors, it is essential to keep the costs of the vessel fleet used for O&M tasks at minimum level while providing sufficient support to sustain power generation. In order to address these issues, the focus of this paper is to provide decision support for the selection of a Crew Transfer Vessel (CTV) fleet for the offshore wind farm maintenance operations. This is achieved through analyses of environmental conditions, investigation of failures, and assessment of vessel operations. The developed methodology and analysis enable operators to decide the specification of CTVs which will bring the optimum financial benefit, considering both the enhancement of the offshore wind farm power generation as well as the minimisation of the total O&M cost.
