| Safety Critical Element Management Manual EP 2009-9009 Restricted 3 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 of SCE 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 and De-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 Critical Elements (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 Technical Integrity 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 SCE Management 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.
