Installation, Commissioning and Validation
Local Fuel plc or the System Integrator will employ sub-contractors to install the SIS. All
installation work will be carried out by technicians who are competent in both SIS and
hazardous areas working and will be undertaken by CompEx certified technicians, or at a
minimum the final inspections, prior to energising the system, must be carried out and
documented by a CompEx certified technician.
Local Fuel plc will ensure that the Installation Contractor has all required documentation in
order that the installation will comply with the design. It is the Installation Contractor’s
responsibility to ensure that any changes during the installation are advised and agreed with
the designer and supported with information to allow As Built documentation.
Installation testing documentation is to be provided by the Installation Contractor to Local
Fuel plc or their representative for inclusion into the Safety Instrumented System Manual.
On completion of the installation the full system will be pre-commissioned and validated to
ensure the installed SIS meets the requirement of the design for both functional safety and in
compliance with BS EN 61511.
Full and comprehensive records will be produced and retained of the installation,
commissioning and validation detailing test results, instrumentation calibration, procedures
used and any discrepancies between actual and expected results. This documentation will be
included in the Safety Instrumented System Manual.
As shown in Figure 1, validation of the Installation and Commissioning is required at this
lifecycle phase. The Functional Safety Manager is responsible to ensure that this validation is
completed as defined in the Safety Plan. Local Fuel plc have developed checklists to record
the verification of the validation process.
A Functional Safety Assessment (FSA) Stage 3 is to be performed. The Functional Safety
Manager will arrange for an assessment to be conducted.
