Background 415

The SCR (as amended by DCR) and PFEER regulations further define the
requirements for the establishment of performance criteria, against which those sys-
tems critical to safety can be measured and recorded, and for documented schemes,
which describe how verification of adequate performance is achieved.
SCR Regulation 15 requires identification of Safety and Environmentally Critical
Elements (SECEs) by the duty holder and examination of these, by Independent and
Competent Persons (ICPs), to verify suitability and adequacy. Standards for verifica-
tion are the performance requirements established by the duty holder specific to each
asset/installation – Verification Scheme.
PFEER Regulation 19 requires a Written Scheme for the systematic examination,
by a competent and independent person, of plant identified within the PFEER assess-
ment (Reference Regulation 5).
Industry practice and work processes have led to a Combined Scheme to satisfy
both PFEER and SCR, although it is acceptable to write two separate schemes (duty
holder decision).
A full lifecycle scheme which would cover all phases of an installation’s lifecycle
(design, construction, installation, commissioning, operation, decommissioning and
abandonment) is an efficient way both in terms of cost and time, and provides a
smooth/continuous handover of the scheme from one phase to the next.
Due to the non-prescriptive nature of the regulations, and the fact that the full
responsibility for demonstration of legislative compliance rests with the installation
duty holder, there are diverse routes by which compliance can be achieved.
