Prof. Chou Loke Ming
National University of Singapore, Singapore

 

Dr. CHOU Loke Ming is Emeritus Professor at the National University of Singapore (Department of Biological Sciences). He obtained his PhD in Zoology from the University of Singapore in 1976. His research on coral reef ecology and integrated coastal management covers Southeast Asia. His current research focus is reef restoration and he is particularly interested in how corals can be re-established in the highly turbid conditions of rapidly developing coastal areas. He is an Honorary Fellow of the Singapore Institute of Biology and a Fellow of the Singapore National Academy of Science.

Speech title-"Remaining useful life estimation of structure systems under the influence of multiple causes: Subsea pipelines as a case study"

Abstract — In dynamic complex environments, the degradation of structure systems is generally caused not by a single factor but by multiple ones, and the process is subject to a high level of uncertainty. This paper contributes a hybrid physics-model-based and data-driven remaining useful life (RUL) estimation methodology of structure systems considering the influence of multiple causes by using dynamic Bayesian networks (DBNs). The structure model and parameter model of DBNs for the degradation process caused by a single factor are established on the basis of theoretical or empirical physical models, thereby solving the problem of insufficient data. An RUL estimation model is subsequently established by integrating these degradation process models. The RUL value is obtained from the time difference between the detection point and predicted failure point, which is determined using the failure threshold of performance. The sensor data and expert knowledge can be input into the estimation model to update the RUL value whenever necessary. Subsea pipelines in offshore oil and gas subsea production systems are adopted to demonstrate the proposed methodology. The degradation processes with fatigue, corrosion, sand erosion, and internal waves are modeled using DBNs, and the RUL is estimated using DBN-based RUL methodology.

 

 


 

Edmond Yat-Man LO
Associate Professor, School of Civil and Environmental Engineering
Deputy Director, Institute of Catastrophe Risk Management (ICRM)
Nanyang Technological University, Singapore

 

A/P Edmond Lo is currently the Deputy Director of the Institute of Catastrophe Risk Management (ICRM) at NTU, Singapore. He joined NTU in 1996 where he was Head of the Division of Environmental and Water Resources Engineering (2005-08) and Chair of the School of Civil and Environmental Engineering (2008-2011). A/P Lo’s current research work is in flood risk management for S.E. Asian cities with a particular view of how flood resiliency evolves as cities develop under the influence of growing urbanization and climate change. He co-leading ICRM’s efforts in the CREATE Future Resilient Systems program, a multi-university effort led by ETH Zurich. He is also co-PI in ICRM’s flagship Natural Catastrophe and Data Analysis Exchange project wherein high resolution satellite imaging is being applied to develop building exposure models for risk assessment in major Southeast Asian cities.
