Functional Safety Implementation Plan
Closed
Description
Gaps were identified against recommended good practice and these have been raised as
individual actions (2 through 8). A Functional Safety implementation plan should be produced
which identifies how and when these gaps will be closed. The plan should include all the stages
of the FS safety lifecycle.

Management of Functional Safety
Closed
Description
The Company does not have SIS management policies and procedures in place that describe
how the Shoreham Terminal plan, specify, design, install, commission, operate and test SIS.
The Company should therefore produce and implement suitable Functional Safety management
policies and associated procedures for the Shoreham Terminal. These documents should detail
how all the safety lifecycle stages are managed and implemented including defined roles and
responsibilities, SIS asset register, obsolescent equipment (end of life), logging true demands,
spurious trips, management of change (modification of SIS) and decommissioning.

Hazard Analysis, SIL Assessment & Safety Requirements Specifications
Closed
Description
The Company should complete the hazard analysis and SIL assessments for the Shoreham
Terminal operations including MLA’s, Tanker Loading and Jetty operations. The HA activities
should include all credible Major Accident Scenarios and result in the identification of all safety
functions.
The Company should determine SIS integrity using a suitable SIL assessment technique (stated
to be the LOPA). The assessments should consider Human Response, utility failure and IPL’s
should be independent and reliability data justified and referenced (traceable).
Safety Requirements Specifications for each SIS should be produced to include (but not be
limited to) documented Safety function, integrity, architecture, response times, operation,
diagnostics, inhibits, interfaces, test frequency and MTTR.
