Maintenance Grouping Optimization for Offshore Wind Turbine Considering Opportunities Based on Rolling Horizon Approach

Abstract

In future, offshore wind turbines may be consider a crucial part in the supply of energy. Maintenance processes are directed to attain a safe and reliable operation of offshore machines and wind turbines. In this paper, an opportunistic maintenance strategy for offshore wind turbine is proposed, considering imperfect maintenance and the preventive maintenance durations. Reliability Centric Maintenance serves as a proactive tactic to operations and maintenance by inhibiting the possible reasons of poor performance and controlling failures. Other components can implement the opportunistic preventive maintenances if one component has reached its reliability threshold. According to the rolling horizon approach, it is of great importance to update the maintenance planning for the sake of the short-term information. By figuring out the best combination, the maintenance schedule in the mission time has been finally determined. Failure information are obtained from previous studies to accomplish the calculations. The outcomes indicate that the maintenance cost has been dramatically reduced through the application of opportunistic maintenance.

Condition-based multi-component maintenance decision support under degradation uncertainties

“…where maintenance is often not easily accessible and the rental and operating costs of these pieces of equipment are substantially high (Wang et al 2021). Each visit consists of a substantial setup cost that may be incurred from the transportation cost of vessels, finding the right crews for the jobs, ordering of spare parts, etc., and Lua et al (2018) showed a significant cost reduction in maintenance cost applying an opportunistic grouping approach compared to the schedule-based maintenance policy. Similar application areas are foreseeable in the development of unmanned and minimum manned platforms in the North Sea such as the Oseberg H from Equinor in the Norwegian Continental Shelf (NCS).…”

An opportunistic maintenance strategy for wind turbines

“…Yang et al [10] designed a windcentred maintenance policy integrating multiple maintenance opportunities, which successfully integrated diverse impacts of wind conditions and resource constraints into the decisionmaking process. Patriksson et al [11,12] established a stochastic opportunistic maintenance model where short-term and predictive information was integrated to make decisions for a fleet of wind turbines [13][14][15]. Erguido et al [16,17] proposed a dynamic OM strategy involving a reliability threshold that varied according to the weather conditions.…”

Enhanced POM strategy and its application to wind turbines

“…Zhu et al [10] considered periodic routine maintenance that was scheduled at a fixed period and reactive maintenance that was instructed by the imperfect prediction signal. The literatures [11][12][13][14][15][16] considered short-term condition information in opportunistic maintenance. Luo et al [11][12]] took short-term information into account by the rolling horizon approach.…”
