Title: Strategies for Maintenance Planning of Floating Offshore Wind Turbines
Abstract: An overview will be presented of the overall trends of production of wind energy worldwide, including its evolution offshore. The general characteristics and mode of operation of the wind turbines is presented and the use of FMEA for identifying the modes of failure and their risk levels is discussed. Reference is made to existing databases of failure data and the problem of estimating failure rates of the various components is addressed. Given the lack of data for offshore wind turbines a method is presented to adjust failure data from onshore to offshore conditions using expert opinions. Maintenance models used for Floating Offshore Wind Turbines are mentioned and risk-based maintenance planning and health monitoring are described. Given the nature of the platforms and the difficulty in accessing them with specialized vessels, opportunistic maintenance is more important than in installations onshore. So, strategies for opportunistic maintenance approaches are discussed and problems are identified.

Lu Jin, Professor
University of Electro-Communications, Tokyo, Japan
Title: Optimal Policies for Condition-based Maintenance
Abstract: With the improvement of ICT technology, maintenance policies have gradually shifted from corrective and time-based preventive maintenance to condition-based maintenance. In condition-based maintenance, the underlying condition of the target system is periodically observed by sensors. Appropriate maintenance is carried out when the system is judged to be operating abnormally (dangerously) or to require maintenance in accordance with the observed information on the target system. One of the current challenges with condition-based maintenance is how to search for the optimal policy. This talk will focus on the optimal decision-making of condition-based maintenance. Research on optimal maintenance policies has mainly followed one of two approaches. The first involves finding computationally feasible algorithms for solving the optimization problem. The second approach of research on optimal maintenance policies is to specify the structural properties of the optimal solution to help determine an optimal policy more efficiently. This talk will review the recent research on the optimization of maintenance policies in both approaches, then discuss the structural properties of maintenance policies for complex systems based on both theory and simulation-based results.

Title: Location Problems in Lamp Systems Considering System Reliability
Abstract: In this talk, I introduce location problems in two-dimensional lamp systems considering system reliability. Suppose n lamps are used to cover the service area, where each lamp can cover a circular area with a radius r. The lamp could be failed with some probability and the system is working when working lamps cover the whole service area without any dark areas. The system reliability is the probability that the whole area is covered by working lamps. The lamp location problem is to determine the locations of lamps in the service area to maximize the system reliability. Firstly, I explain how to calculate the system reliability in two-dimensional lamp systems. Secondly, heuristic methods are proposed to determine the lamp locations. Finally, we investigate the performance of the heuristic methods proposed by numerical examples.

Title: Ruggedness and Reliability of SiC MOSFETs
Abstract: The superior characteristics of Silicon Carbide (SiC) render it an optimal replacement for Silicon-based power electronic components in applications requiring high efficiency, high frequency, and elevated temperatures. With the development of new-generation power electronics systems, including applications in photovoltaic systems, electric vehicles, charging piles, and so on, SiC MOSFET (silicon carbide metal-oxide-semiconductor field effect transistors) is accelerating the replacement of Si-based devices. Although SiC MOSFETs have superior performances to Si devices, obvious differences between the properties of SiC and Si materials and devices provide challenges to the ruggedness and reliability of SiC MOSFETs. A few potential reliability issues are associated with SiC MOSFETs, including threshold voltage instability, gate-oxide reliability, body-diode degradation, etc. Extensive characterization studies of SiC MOSFETs’ endurance capability under harsh conditions including unclamped inductive-switching (UIS), short-circuit (SC), transmission line pulse (TLP), power cycling (PC), high-temperature gate bias stress (HTGB) and radiation effects have been reported by our team. The ruggedness and reliability of SiC MOSFETs under different conditions will be discussed here.
