Design process maintenance phases

After tlie system has been defined, a hazard evaluation technique can be used to identify different types of hazards within tlie system components and to propose possible solutions to eliminate the hazards. This topic is treated in more detail in the next t o chapters. These procedures are e.xtremely useful in identifying system modes and failures that can contribute to the occurrence of accidents diey should be an integral part of different phases of process development from conceptual design to installation, operation, and maintenance. The hazard evaluation tecliniques tliat are useful in tlie preliminary and detailed stages of tlie design process include ... 

Once this Asset design has been defined and built, the production phase can commence. In order to ensure that the inherent capability of the Asset is delivered as per the shareholder promises, it now becomes paramount that the capability is maintained. This process runs in reverse order to the design process. In order to maintain the Technical Integrity, it is important to understand the degradation mechanisms in the plant. Structured processes like Risk Based Inspection, Reliability Centered Maintenance, and Instrumented Protective Function classification, are applied to define the work scope to maintain Technical Integrity. These processes generally determine the scope and... 

The purpose of the I C system documentation is (1) to provide the means of communicating information between the various phases of and the various parties involved in Ihe design process (2) to provide a record that shows that the requirements have been correctly interpreted and fnlfiUed in the installed system (3) to communicate operationally essential design related information to the plant operators and (4) to provide a fonndation for plant maintenance and for potential future revisions to the design. 

The design assessments and basis of safety must be recorded and available for consultation, and the process must be operated as required. The operating phase involves two sets of process documentation—the detailed technical documentation, and safe operating instructions (HSE 2000) for every operational phase, including startup, shutdown, maintenance and emergency operations. 

Goals and Objectives of FEL The FEL work process must enable nearly constant consideration of changes as the work progresses. FEL phases must consider the long-term implications of every aspect of the design. Predictability of equipment and process system life cycle costs must always be balanced with operations and maintenance preferences, as well as the need for the project to maintain its profitability or ROI (return on investment). Additional important goals and objectives of FEL projects are as follows ... 

The design, development, and system build phases need to deliver computer systems and services in a manner that facilitates effective and efficient system validation, operation, maintenance, modification, and upgrade. This applies to both stand-alone and embedded process control computer systems (see Sec. VI). 

Develop an adequate and economical process design (Phase 0) that is consistent with the design, operating, and maintenance criteria established by the Venture Manager.
