International standards IEC 61511 and IEC 61508 provide guidance for implementing the safety system life-cycle phases. Armed with this knowledge safety design engineers may feel that they can tackle any project. However, the scope of a safety system project can vary considerably. The SIS may be part of a new multibillion dollar process plant, a facility revamp or just involve the addition of a few safety functions to an existing installation. The execution will vary considerably depending on the overall scope and makeup of the project even though the basic steps will be similar in concept.
Most importantly, the overall project schedule and resourcing is often governed by scope other than the safety system. A large project may take four to seven years from conception to startup. Essentially the safety engineer must navigate many interfaces in order to formulate a solid SIS design basis (i.e. safety requirements specification). It is important to understand! the complexity that arises from these interfaces; they need careful management.
