Lunch and networking


Interactive session: What would you like to see in Edition 3 of IEC 61508?

A brief introduction will be given by the two facilitators and the session will then be fully interactive.

The process for revising IEC 61508 is planned to start very shortly and the session is intended to stimulate discussion on the future direction and content of the revision process.

This will cover:

  • Technical changes to the standard that users would like to have implemented
  • Level of involvement that users of the standard would wish to have
  • General discussion on any matter raised by the audience


Ron Bell, Chair of IEC Maintenance Team 61508-1/2

Regulation of the security of computer-based systems important to safety in the nuclear sector

Pete Dyer, Control and Instrumentation Specialist Assessor, Office for Nuclear Regulation


Keeping SIS secure in an integrated, open automation environment

Paul Hingley, Safety, Product and Solution Security Officer, Siemens UK
Ian Curtis, Process Safety Consultant, Siemens


Refreshments, networking opportunity and exhibition


Software proven-in-use – New requirements in IEC TS 61508-3-1

This presentation will summarise the proven in use evidence requirements in IEC 61508 Part 2, outline the key additional requirements for software in TS 61508-3-1, and describe some of the practical difficulties which might be encountered in providing a convincing proven-in-use case.

Ronald Pierce, Functional Safety Consultant, Hitachi Information Control Systems Europe Ltd.


Case study: When trust breaks down: achieving functional safety in an atmosphere of animosity

This talk describes the approach we took to resolve a log jam in a cogen power plant development project in Australia. The importance of the following aspects is emphasised, and practical solutions discussed:

  • A clear, agreed and detailed Functional Safety Management Plan
  • Documented, auditable justification of the decisions made in the SIL determination activity
  • Resolution of disputes based on data and evidence, not gut feelings or personal experience alone
  • Demonstrable, documented verification of each lifecycle phase

Dr. Peter Clarke, Managing Director, xSeriCon


Panel discussion: Product safety guide and standard proposal

The Defence industry has since the 1990s faced two key (product) safety management standards that are widely invoked in contracts, these being:

  • UK - Defence Standard 00-056 - Safety Management Requirements for Defence Systems
  • USA - Military Standard 882E - System Safety - It is proposed that an industry developed guide / standard (agreed with the civil and military regulators) could better continually promote product safety

Andy German, Chief Engineer, Professional Head of Discipline – Safety, Technical Authority – Safety - Land & Strategy, ATKINS
Graham Jolliffe, Managing Director, Jolliffe Assurancy Services Ltd


Chairman’s final remarks and close


9 December 2016 - workshop 1

Timings to be confirmed

How safe is safe enough?

Setting the target risk and demonstrating the tolerable risk in SIL determination.

The Workshop will explore target risk and tolerable risk concepts as part of the achievement of functional safety. During the workshop several interactive examples will be provided.

The workshop will include the following:

  • The legal requirements within the UK applicable to functional safety
  • The concept of “so far as is reasonably practicable” and “as low as reasonably practicable (ALARP)
  • HSE’s policy relating to functional safety and HSEs “delivery guides” covering functional safety
  • The concept of “good practice” which is fundamental to underpinning the ALARP demonstration
  • The role of international standards and guidelines in achieving “good practice”
  • Demonstrating ALARP including applying cost benefit analysis
  • The role of SIL determination in achieving the tolerable risk
  • The role of SIL determination in achieving the tolerable risk
  • The role of SIL determination in achieving the tolerable risk

Workshop leader:
  • David Green, BEng(hons) CEng MIET MInstMC RFSE


9 December 2016 - workshop 2

Timings to be confirmed

Securing industrial control systems

Security of Industrial Control Systems (ICS) is now a prime focus in today’s leading industrial process automation and factory automation end users. With so much equipment now networked over Ethernet, no longer using niche protocols, and with technical know-how public knowledge, the attack surface has grown.

This workshop aims to provide:

  • Introduction to the current threat landscape of ICS
  • Overview of IEC62443 security standard
  • Overview of the “Defense in Depth” strategy
  • Safety Instrumented Systems (SIS) and security
  • Best practice network security
  • Defense methods such as continuous security event monitoring with SIEM, Whitelisting, Anti-Virus, IDS/IPS, patching (Firmware and OS) and firewalls (perimeter and zone)

Workshop leaders:
  • Mark McCormick, BEng (Hons), MIET
  • Ian Curtis, BTech (Hons), IEng MIET
