Event Summary:

Presentation to North West Branch 30th June 2016, Graham Dalzell “Dangerous Decisions, Lessons from Andrew Hopkins’ study of the Macondo Blowout”



Presentation to North West Branch 14th May 2015

On Thursday 14th May 2015, Pete Stanton delivered a talk on ‘ALARP in the Rail Industry’ to the well-attended North West Branch meeting, held at Birchwood Gold Club in Warrington.

Pete, a Senior Asset Management Analyst at Network Rail and the Financial Director of Safety and Reliability Society, gave a detailed overview of the way the Rail Industry is structured and explained the way in which Network Rail is organised and operates.  The Safety Risk Model outlined by the Rail Standards and Safety Board (RSSB) is used by Network Rail to calculate the causes and consequences of hazardous events. Through their Fault Tree Analysis example Network Rail are able to monitor any risks and continue to improve safety on the railways and at train stations.

Using comparisons with the 15 largest European Union railways, Pete’s work led him to deliberate over statistics that showed the trend of passenger accidents in each country. The United Kingdom has the lowest passenger risks with 1.81 FWSI per billion train km according to 2009-2013 figures. This is compared to Romania who has 37.27, making the UK railways reasonably safe. Research into the common safety methods around Europe found similarities with the European Legislation to simplify interoperability.

Asking the question “what do common safety methods apply to”, Pete explored the significant changing factors;

  1. Additionality: have there been other small changes since the last assessment which should be taken into account?
  2. Reversibility: can the change be reversed?
  3. Monitoring: can the change be monitored through the system life-cycle?
  4. Failure consequence: what is the credible worst-case outcome?
  5. Novelty: new for you, new for whole railway?
  6. Complexity of the change

The second factor when thinking of common safety methods is hazard identification. Pete explained that the system must be properly defined; taking into account what could and should be in the scope. Through the hazard identification process, HAZID sessions must be run as well as the creation of hazard logs. Then there must be an initial classification of hazards to assess whether they’re broadly acceptable and if so, the hazard log should be closed.

Risk Assessment Routes are the third common safety method where each hazard can choose between:

  • Relevant standards
  • Reference system
  • Risk assessment

The fourth common safety method is Demonstration of Compliance to confirm that requirements have been met through the process. Network Rail uses a whole life costing system to calculate the value of its assets. Pete concluded that Network Rail embrace change, in all its forms – engineering change, service change, level crossings and complex change with the Digital Railway.

The Re-Launch of the North West Branch

  • The first Branch meeting, to kick-start a series of evening talks and discussion sessions was on Thursday, 11th September 2014 at Birchwood Golf Club, Warrington at 1730. The event addressed topics which are of relevance to Safety and Reliability Professionals and are an excellent method of keeping informed of current developments; additionally the meetings are an ideal networking opportunity.
  • SaRS headquarters hosted a talk, ‘‘Delivering ALARP in Network Rail” from Pete Stanton on Tuesday 24th January, 2012.
  • The first talk of 2011 was given by Mr. Graham Dalzell “Risk Assessment – One Size Does Not Fit All” as part of the Open Evening held on 15th September, 2011. This was followed by a discussion of lessons emerging from the Fukushima accident presented by Mr. Andrew Coatsworth of Sellafield Ltd held on 5th October, 2011.
