Introduction
The objective of this manual is to describe the Globally mandated process which is applied during an Asset’s Operate phase to provide assurance that the physical hardware barriers (SCEs)
are in place and working to prevent initiation or escalation of major incidents or, if they are not, that risks are appropriately assessed and mitigating actions taken provide transparency and visibility
of the management ofSCE performance assurance standardise the processes and use of the available supporting tools.
This manual covers those activities within the EP Business Model processes EP.64 (Design, Construct, Commission,
Modify andDe-Commission Facilities, EP.65 (Execute Operations Readiness and Assurance Activities) and EP.72 (Maintain and Assure
Facilities Integrity) which are used
to manage the Safety CriticalElements (SCEs). It is also applicable to wells SCEs, since the custody of wells is the responsibility of the Production organisation during the Operate phase. The activities are identification of SCEs
• development of Operate phase elements of performance standards and performance assurance tasks alignment of performance assurance tasks with other planned maintenance
routines identification, control and closeout of non-conformances through a deviation management process
• reporting of deviation status.
The term ‘SCE Management covers the method of providing workable,
sustainable, measurable and standardised processes and tools to assure the performance of SCEs to demonstrate that these hardware barriers are in place and effective.
In all other sections, shall and should have the following meanings.
The word shall indicates a mandatory requirement governed by this manual.
The word should indicates a recommendation or guideline.
Shell’s Group Asset Integrity Process Safety Management
Standard
requires that, Businesses shall define, comply with and manage deviations from performance criteria for all identified hardware barriers critical to Asset Integrity Process
Safety”. The implementation of this requirement in EP is further defined in the Technical Integrity Framework (EP.03.ST.04). Following the requirements of this manual will ensure compliance with the SCE Management
aspects of the TechnicalIntegrity Framework during an Asset’s Operate phase.
However, legislative requirements may demand that additional measures shall be put in place. An overview of how this manual interfaces with other EP manuals, guides and systems is shown in Figure 1 and the relationship with the EP Business
Model is given in Appendix 1.
The description of the SCEManagement process has been divided into five sections.
These sections provide an overview of the process, highlighting the main requirements and explaining why these are important to the success of the process and the business.
There are also appendices which provide more detailed information on particular aspects of the process. These are included at the end of this manual. Further reference material,
such as Global
Performance Standard Templates, are accessible through Shell Wikipedia in SWW.
