exida: Perfecting Proof Test Effectiveness
Period functional tests are necessary to ensure the appropriate safety integrity is maintained. These tests can be disruptive and intrusive in the process. However, in general the necessity of the tests is accepted. The 2nd edition of the IEC 61511 functional safety standard for the process industry sector identifies the need to take the proof test effectiveness into consideration. This proof test effectiveness indicates the percentage of undetected failures revealed during a proof test. This parameter can have quite an impact on the overall achieved safety integrity. This presentation will discuss the concept of proof test effectiveness and show how more extensive tests will improve safety and at the same time can potentially reduce cost.

IChemE Safety Centre: Gas Plant - Simulating operational decisions
This presentation will demonstrate a stream of crucial decision-making points, which would typically occur while on shift, operating a gas plant. It will explore equipment suitability, alarms and the pressures of production.

exida: High and Continuous Demand LOPA Considerations
LOPA is becoming the preferred choice when performing SIL determination, resulting in LOPA is also being applied more and more to high demand and continuous mode safety functions as functional safety expands new industries and technologies. Although LOPA can add a lot of value to high demand and continuous mode risk analysis, there are a number of issues which must be properly handled to avoid dangerous mistakes. This presentation will focus on how to correctly apply LOPA to high demand and continuous mode safety function risk analysis, while noting the critical considerations for these risks.

Industry Trends and Knowledge Sharing Session
Our panel of industry experts get together on stage for an interactive discussion with the audience.


Iwan van Beurden, CFSE Chief Technology Officer, Director of Product Development, exida
Iwan is the Chief Technology Officer, Director of Product Development at exida. He supports exida's end-user services, exida's manufacturer services, and exida certification activities. He has over 20 years of professional experience in the Functional Safety field. Iwan is responsible for the development, maintenance, and certification of the exSILentia integrated Safety Lifecycle tool and associated products. Iwan also performs IEC 61508 development support, Functional Safety Assessments, and a variety of reliability analyses. He supports all safety lifecycle tasks, ranging from the Process Hazard Analysis, Layer of Protection Analysis, SIL Selections, and SIL Verifications, to proof test specification and operational event recording. Iwan also performs process gap analyses to determine the level of effort companies need to undertake for compliance with IEC 61508 or IEC 61511. He gives training for exida and is also an ISA fellow and instructor.

Iwan previously worked for Yokogawa Industrial Safety Systems in Apeldoorn, the Netherlands. He worked both in the R&D and in the Operations department as a Safety Assessment specialist. He was involved with the implementation of IEC 61508 within Yokogawa Industrial Safety Systems dealing with SIS reliability calculations and the safety education of engineers. Iwan is a Certified Functional Safety Expert (CFSE) and a member of ISA. He has published various papers and magazine articles. He holds a Master of Science degree from Eindhoven University of Technology in Eindhoven, the Netherlands, where he majored in reliability engineering and graduated cum laude.

Trish Kerin Director, IChemE Safety Centre
After graduating with honours in mechanical engineering, Trish spent several years working in project management, operational and safety roles for the oil, gas and chemical industries.
Trish's passion for process safety saw her take on advisory committee roles with the Plastics and Chemical Industries Association (PACIA), WorkSafe Victoria Major Hazards Advisory Committee and represented the Australian Chamber of Commerce and Industry (ACCI) to Safe Work Australia .Trish has previously sat on the board of the Australian National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) and is a member of the Mary Kay O'Connor Process Safety Center steering committee.

Trish is a Chartered Engineer, a registered Professional Process Safety Engineer and Fellow of IChemE. She holds a diploma of OHS is a graduate of the Australian Institute of Company Directors (GAICD) and a Fellow of Engineers Australia (FIEAust). She was recently awarded a Master of Leadership. In 2015 Trish was awarded the John A Brodie Medal from Engineers Australia for the best paper at the Asian Pacific Confederation of Chemical Engineering Congress 2015 (incorporating Chemeca). The award recognises Trish's peer reviewed paper on Process Safety Competency. In 2018 Trish was awarded the Trevor Kletz Merit Award by the Mary Kay O'Connor Process Safety Center for her work in advancing process safety worldwide.

Sam Holden Operations Manager and Principal Engineer, exida Australia
Sam is the Operations Manager & Principal Safety Engineer for exida Australia. Sam is an experienced EC&I and Functional Safety Consultant with more than 20 years industrial experience in specification, design, commissioning, modification and maintenance on instrument and control systems. Sam has worked on projects within the petrochemical, refinery, pharmaceutical, oil and gas, chemical and mining industries.

Sam has been working with safety related systems since year 2002 and has gained detailed knowledge of functional safety lifecycle management including implementation, planning, realisation, classification, verification & validation across various different process industries. Sam is a co-author of the Practical SIL Target Selection textbook issued earlier this year. Sam is a Chartered Engineer, RPEQ, Certified Functional Safety Expert (CFSE), IICA Queensland committee member and the Australian representative for the IEC 61511 committee and the Chairman of IT-006 committee (TC65 mirror committee) for Standards Australia.
