As you can see, in these situations of conflicting standards references the detailed scope and design
basis needs to be established early on. This is one of the roles of the FS manager. If this is not done
it can result in contractual disputes between client and EPC or EPC and SIS supplier, and once it
reaches this stage the implementation of IEC61511 is at risk.
6) FS MANAGER ACTIVITIES
As we have seen, a competent FS manager is essential for a successful implementation of IEC61511.
Typical FSM activities and responsibilities are as follows.
a) FS Management Plan
Produce the FS management plan to define how 61511 will be implemented in relation to the
contract scope, including:
Competency assurance and management
Tolerable risk definition
Tracking from HAZOP through to operations
SIL assessment TOR
Relevance of asset protection
SRS requirements
Realisation strategy, especially if a hybrid
Verification, validation and FSA strategy
Commissioning requirements
Operations preparation, procedures and training
This plan is a live document and will be produced in stages as the project detail and personnel
develops.
b) Other planning activities
Plan from the beginning with project management what activities are required and when.
IEC61511 is not an expensive or schedule-busting activity if planned from the start by
someone who understands how it is done. Backtracking later with design or suppliers is very
painful
Identify required resources and training to meet competence requirements. Certification
does not mean competence. Competence can only be assessed by someone who is
themselves competent.
Identify any third party requirements and resources for activities such as SIL Assessment
Chairman, SIL Validation etc.
Do all that is possible to assure understanding of the systematic issues
Set the FSA strategy. Do not leave it all to FSA3. Make the FSA a semi-continuous process
and choose the right assessor.
Establish an early link with operations to ensure the operations team have the necessary
training, procedures etc.
