Plans are ultimately only as good as their execution. Without proper and timely execution, even the best safety measures and procedures will be ineffective. To improve the effective execution of critical safety processes and equipment a concise definition of expectations must be linked to the task and equipment performance measurements. This is accomplished through the development of Asset Integrity Performance Standards, which will be described in this paper.

ADGAS has developed a set of Performance Standards for Health, Safety and Environment Critical Equipment and Systems (HSE-CES) in compliance with a larger mandate in the ADNOC group of companies to assure the safety and integrity of its assets. These standards are grouped according to the common designations of barriers used in the "Bow-tie" diagrams for process safety. This assures the managers that all aspects of preventive and mitigation barriers are in place. The Performance Standards themselves are a compilation of references forming a continuous link from the design standards employed to achieve the stated objectives of the barrier to the final audit functions and document locations used to assure their proper implementation.

The use of these Performance Standards greatly improves the understanding of the processes and the asset criticality throughout the organization and provides a high level of transparency to the activities performed to assure continuing reliability and integrity of the assets. The integration of the entire lifecycle and purpose of critical assets into a single document (for each barrier type) is a best practice development from the previous independent collections of design, maintenance, inspection and audit specifications and records.
