Ongoing: Train collision risk modelling and layout risk assessment

Sotera is currently developing, with RSK Business Solutions, a suite of tools for the management of collision risk on railway infrastructure. The tool will represent a significant advance over existing methods in that the modelling simulates the real demands on the railway and the controls that are in place, such as real timetables, train performance and dynamics, train control systems, train protection, signalling, topography, railway interlocking and flank protection. The suite of tools is targeted at the rapid and efficient assessment of risk control measures to help achieve the optimal balance between safety, operational performance and cost.

Just complete: Gaz de France: Algerian Gas Processing and Transmission

Sotera carried out a quantitative risk assessment (QRA) of the drilling of gas wells and operation of the Central Processing Facility (CPF) and gas and CO2 transmission lines.  Recommendations were made with respect to layout and emergency planning.

Just complete: Crowding and congestion management at stations

Sotera completed a research project for RSSB targeted at reducing crowding and exit times at busy terminal stations.  Crowding is undesirable as passengers are delayed on their journeys, can become dissatisfied with the service and there is an increased risk from assaults and personal injury.  The project investigated the effect on safety and performance of a modification to terminal station layouts.  The modification involved increasing the space passengers can walk on between the buffer stop and the ticket gates through the use of collapsible decking.  The assessment included dynamic modelling of crowd flows, analysis of human behaviour, predictive risk modelling and cost benefit analysis.  The results of the assessment and report can be found on the RSSB website (search for project reference T772 at www.rssb.co.uk).
