2010 - Power/oil
Andy was asked to carry out an alarm audit at a facility controlling power generation and supply to oil production sites. Over 20 gas turbines and a distribution network were controlled from a central location. Andy found that the system had evolved over a number of years, resulting a mismatch of control and monitoring technology being used. All had their own alarm systems, with varying problems and were in desperate need of review and rationalisation. Andy identified that operators were overloaded with alarms, but had developed coping strategies that allowed them to prioritise their actions. He provided the client with a plan to fundamentally change the way alarms were being managed that would improve reliability and process safety. This was very well received, and Andy was asked to return to implement the proposals at a new facility. In fact the client was so impressed they offered a financial bonus.
