| 8.2 VERIFICATION IN THE CONCEPT, FEED, DESIGN, CONSTRUCTION AND COMMISSIONING PHASES During these initial phases of a development project, the duty holder is required to demonstrate initial suitability of SCEs through the following Consideration of the design Confirmation of the adequacy of manufacture, fabrication and installation Demonstration during commissioning that the SCEs are capable of meeting the required performance standards. The ICP’s role is to carryout independent examination of documents, activities and plant and equipment to confirm the level of compliance with the performance standards. The identification of SCEs and the setting of performance standards are important activities during these pre-operating stages of the project as they provide the foundation for managing the MAH risk. Development of a verification scheme for new construction requires input and coordination from a number of different parties within the duty holder’s organisation, and also from the ICP, design contractors, fabricators and completions team. The early engagement of all parties in the process is crucial to a successful outcome. Particular effort should be made to ensure that previous operational experience is utilised during the detailed design and construction phases. 8.2.1 Major Accident Hazards and SCEs It is usual to produce a document (MAH / SCE matrix) listing the SCEs and describing their derivation linkage to the MAH (See section 5). Where changes to process plant and equipment are undertaken, a similar document should be produced identifying the impact on the existing SCEs of each modification and identifying any new SCEs resulting from the changes to MAHs (see Section 9.1). 8.2.2 Performance Standards for SCEs Once SCEs have been identified, Performance Standards (PSs) need to beset for each (see Section Those PSs associated with establishing initial suitability maybe different to those used to assess ongoing suitability throughout the operational life of the SCE. There area number of ways of dealing with this issue including the development of separate PSs for initial and ongoing assessment and the incorporation of both into a single PS. Regardless of the approach taken, it is essential that the requirement contained in the PS assures that the SCE can fulfil its function. The PS must also be written in such away that it can be clearly established whether or not the required standard of performance has been achieved. Download 274.61 Kb. Share with your friends:
