Description:
It is widely recognised that approximately 90% of plant incidents can be prevented. Moreover, the majority result from the actions or inactions of people. Modern process automation systems have allowed operators to assume responsibility for a larger scope than ever of a plant’s operation. However, as systems become broader in scope, they create the potential to for placing the operator in a weak position. This situation arises because as systems become more complex, they become more difficult to operate.
An OTS is a suitable platform for operators on which to practise because it provides an environment to perform unfamiliar process and control tasks in a safe environment. Any mistake, any error will be converted into a lesson learnt without any real-life consequences. It is key to maintaining the practice of procedures as a regular task for operators and to providing refresher training at regular intervals and for whenever a modification in the plant or in the control or safety system is implemented. Activities with the OTS should include operations such as startup and shutdown ahead of time, and working through the response to infrequent abnormal situations, based on best practice procedures. Training on best practices allow operators to run through the routines on a regular basis, so it is advisable not to allow too much time to elapse between refresher training courses.
