Safety System Lifecycle Design Planning – Case Study

About this project

Scottish and Southern Energy (SSE) embarked on a project to build an underground natural gas storage facility at Aldborough, and appointed AMEC to develop the topside process design, including an integrated control and safety system. In keeping with its policy to use ‘Current Best Practice’ design, AMEC based the process emergency shutdown (ESD) and fire & gas (F&G) systems design on IEC 61508 (Functional safety of electrical/electronic/programmable electronic safety-related systems). By using the IEC 61508 lifecycle design approach, AMEC fulfilled the requirements of SSE, their representative design contractor (Jacobs Engineering) and the Regulator (the Health and Safety Executive - HSE) for safety system design.


“The challenge – The complex nature of the project necessitated the implementation of the topside process design by AMEC whilst SSE and its sub-contractors concurrently prepared the underground natural gas storage caverns, leached out from the subsurface salt strata.”
