Engineering Safety & Risk Considerations hosted by IET Singapore Local Network

Presentation 1: "Railway Safety – How Safe is Safe?"

Speaker 1: Mr Richard Day, Rail Systems Expert, RJD RailConsult 

Synopsis: Safety has always been a key consideration in the implementation and operation of railways.  As social media connects us ever more closely and public perceptions evolve, the rail engineer is challenged to surpass the already high standards of safety and performance achieved with each subsequent project. The presentation will give an insight into how safety considerations are made an intrinsic part of the railway project lifecycle by exploring perceptions and attitudes to safety, putting these into the context of implementing safety management on a new build railway project. The speaker will identify the difference between project and operational safety, including the principles and techniques used in a rail system safety management process.

Presentation 2: "Ensuring Safety in Hydrogen Plants: The SIS Lifecycle According to IEC 61511"

Speaker 2: Mr Chen Zhenkang, Tech Partner at SafetyEra & Senior Consultant at TÜV Rheinland 

Synopsis: This presentation provides an overview of the Safety Instrumented System (SIS) safety lifecycle management as it applies to hydrogen plants, in accordance with the international standard IEC 61511. It will cover the key phases of the lifecycle, from initial hazard and risk analysis through to operation, maintenance, and eventual de-commissioning. It will introduce applying this standard to mitigate the unique risks associated with hydrogen production, storage, and handling. Key topics will include Safety Integrity Level (SIL) determination, detailed design and engineering, functional safety assessments, and the importance of a robust management of change (MOC) process.
