Presentations and dissemination activites in 2017 (27th ESREL)

Hi Guys, I am back to you today to give you some information about my presentations and dissemination activities at academic conferences in the past months.
 


During 17-22 June 2017, I presented a paper Reliability-Based Inspection Planning in View of Both Crack Initiation and Propagation at the 27th European Safety and Reliability Conference ESREL2017 at  Portoroz, Slovenia.

Besides crack propagation, the paper investigates the crack initiation stage of welded structures, which is generally neglected in existing fatigue crack management systems for structural assets. Existing fatigue management systems generally assume that there are initial cracks/flaws in steel structures and the distribution of their sizes are known, and because of those the crack initiation stage is negligible compared with crack propagation. However, the assumptions usually cannot be fully satisfied, especially for some high-quality welds. The paper thus proposes to includes the crack initiation stage while developing inspection programme for such welds, and concludes with recommendations on the inspection method and planning approach to adopt while considering the crack initiation stage.


Management of Crack Initiation, Propagation and Inspection
 

The atmosphere of the conference is quite good in the conference venue Grand Hotel Bernardin, where researchers and professionals from civil/structural, offshore, mechanical, aerospace, nuclear, energy engineering share their ideas and experiences on reliability/risk management. I attended the pre-conference workshop on risk.
 
Workshop on Risk Assessments - Key Challenges and Advances

 
During parallel sessions, more than 450 papers are presented and discussed, among which I have participated in the following sessions.
 
  • Advanced Safety Assessment Methodologies
  • Maintenance Modelling and Applications
  • TRUSS Symposium
  • Maintenance Optimisation
  • Mathematical Methods in Reliability and Safety 
 
On the last day of the conference, there was a discussion session on risk analysis which was quite impressive. Although 'risk' is a very popular word nowadays, its meaning and definition is not fully appreciated by most of us. Fundamental questions are still need to be further studied, such as the link between risk analysis in engineering and in other fields (e.g. finance, health), the difference between specific risk calculation and risk analysis as a discipline, how the assess the qualification of a risk specialist, risk acceptance and communication ...
