1. Identify SCEs and performance standards1.1Identify the Major Hazards This activity is started during the Asset’s Select phase, in which the
initial risks are identified, leading to the controls (barriers)
which are required. SCE group identification and performance requirements are identified using best practice bow-ties. This is continued during the Asset’s Define and Execute phases, during which the detailed process design for the
selected concept is completed, equipment is specified, and the Asset Register built.
The risk studies for the final design
will be documented in theDesign HSE case, and following project completion will be further refined into the final Operations HSE case.
HEMP provides the framework
for managing the major HSErisks to be tolerable and ALARP, and identify the controls needed to manage the residual risk.
During the process,
various HSE studies are undertaken and risks identified,
minimised and recorded in the risk register which is ultimately documented in the HSE Case (EP ST.
As part of the HEMP, Major Hazards are identified using the
Risk Assessment Matrix shown in Figure 4 and described in more detail in the Group
HSE Manual for Risk AssessmentMatrix. Note that Major Hazards which would lead solely to a consequence of business loss, i.e.
loss of revenue, shall not to be considered when identifying SCEs.
