PHM for Gas Turbine Engines
Gas turbines have been widely used in the aerospace and shipbuilding industry, oil and gas pipeline transportation, and industrial power plants due to its excellent performances. As the power heart for these mission critical applications, safe and stable operation of gas turbines is the key. In the operation of the gas turbines, in addition to the harsh operating conditions of high temperature, high pressure, high rotational speed and high mechanical stress and thermal stress inside the engine, it may also suffer from surrounding polluted environmental conditions, and its main components, such as compressors, combustion chambers and turbines, will produce a variety of performance degradation or damage with increasing operating time, and easily lead to various serious failures. In order to improve the reliability and availability of the equipment, while maximizing the service life and reducing the operation & maintenance costs, the users need to adopt the corresponding maintenance strategy according to the actual performance and health status of the engine through monitoring, diagnosis and prognosis means, and condition-based maintenance (CBM).

AI for PHM
Prognostics and health management (PHM) aims at diagnosing the ongoing fault, predicting the remaining useful life (RUL) before failure and scheduling the maintenance/repair action cost-effectively. Given the rapid development of sensor and data transmission technology, big-data becomes one valuable resource for PHM. In the era of big data, artificial intelligence (AI) techniques have gained increasing popularity due to their capabilities of solving large scale problems without much essential domain knowledge. AI has achieved huge success in the fields of the computer vision, natural language processing, game play, autonomous driving, as well as in PHM. For example, the deep learning methods have been applied for the RUL prediction of rotating machinery, battery, etc. In general, the application of AI techniques in the field of PHM can generate enormous benefits for PHM community, both in academia and industry. This special session “AI for PHM” is dedicated for a platform of the exchange of the cutting-edge developments and implementations of AI and data mining methods for PHM.
Advanced Sensing, Data Fusion and Fault Diagnostics
Structural and machinery health monitoring relies heavily on advanced sensing techniques and corresponding information processing engine. Versatile sensing techniques can provide more insight into health conditions of mechanical and electrical systems. Recently, acoustic sensors, optic fibers, infrared sensors, laser sensors, LiDAR and MEMS are all investigated for PHM applications. Furthermore, information from distributed and/or multi-parameter sources requires sophisticated algorithms for feature extraction, multisensory data fusion and intelligent decision making.

Fault Diagnosis, Prognosis, and Health Management for Aircraft Electrical System
The development of science and technology has improved the automation level and increased the number of electrical equipment on aircraft significantly. In addition, the development of more electric and all electric Aircraft also makes the equipment and electrical system on aircraft more and more complex. With this increasing demand of electric energy in aircraft, the requirement for reliability, safety, and maintainability has become demanding. By integrating advanced sensor technology and various intelligent algorithms and modeling tools, prognosis and health management (PHM) technology are used to carry out system state detection, fault diagnosis, prognosis, as well as residual life prediction. PHM also provides suggestions for aircraft electrical system reconfiguration and control in advance, and optimizes maintenance strategies. Moreover, PHM can comprehensively monitor the health status of critical components and the entire aircraft system, which facilitates self-repairing, task relegation, and preparation of necessary maintenance resources in advance, in order to reduce the life-cycle cost. Thus, it is of great significance to carry out the research of PHM for aircraft electrical system.

Safety and Reliability in Water Transport System
Water transport accounts for around 90% of international trade in China because it has the distinguishing characteristics of long transport distance, high volume and low emission. Unwanted and catastrophic accidents occur worldwide, for instances, Costa Concordia (2012), Seoel (2014), and Eastern Star (2016). Therefore, the safety and the reliability of water transport system are still key issues and deserve more attention for risk mitigation. Moreover, with the development of emerging technologies, some emerging safety issues need to be addressed. For examples, the safety and reliability in different regions (Arctic areas), the safety and reliability of advanced ships (using pure electric propulsion, autonomous ships), the reliability and safety of engineering and technology for large maritime systems (offshore wind farms, offshore installations).

PHM for Marine Equipment and Facilities
Marine equipment and facilities, including the marine energy converter, marine platform, AUV, ROV, surface/subsurface buoy, glider and other oceanographic instruments, work in harsh environment. Those rough operating conditions of high salt spray, high humidity, low temperature and high pressure will cause rapid aging and failures of marine equipment. And the marine equipment cost a lot during deployment and maintenance. So their reliability and availability should be considered during the whole life cycle from design, manufacturing and service. PHM methods and technologies provide a lot of knowledge to improve the reliability and availability of the marine equipment, while maximizing the service life and reducing the operation & maintenance costs. Both the researchers and the users should focus on the monitoring, diagnosis and prognosis technologies for not only the electrical system but also the structures and mechanical components for those marine equipment.
