c) Project activities
Ensure the HAZOP is properly documented with consideration given to later SIL assessment
activities. A clear method of tracking from HAZOP hazard right thought all later phases is
essential.
Consider in design likely high risk (high SIL) areas to avoid frequent testing that impacts
operations, e.g. redundancy of valves, to avoid later design changes.
Equipment and package specifications must consider any potential FS requirements to avoid
later disputes with suppliers. Note the new and more onerous requirements for suppliers
related to their FS management in the latest edition of IEC61511
Ensure design change management procedures reflect FS requirements at the correct life
cycle stage
7) KEY MESSAGES
Some key messages I would like you to take from this presentation are as follows.
Consider the FSM plan from the very beginning, even bid or FEED
Make sure whoever is responsible for FS really understands both the technicalities of the
standard and how projects work. An academic approach is of little value if it conflicts with
the prime drivers of the project, schedule and cost.
The FS management plan is the key document and the first issue must be very early
Contractual disputes between Operator, EPC and suppliers can become a major obstacle to a
successful implementation. Clear scope definition is important here.
Adopt a semi-continuous FSA strategy with the right (pragmatic) assessor. Go for a person,
rather than a company.
