|2.1.1 HSE Management Systems
Safe operation and maintenance of emergency systems are of primary importance to the process industries, including upstream oil and gas. One of the critical elements of emergency system is proper documentation and ever greening of the process safety information. Significant time and experience in the onshore process industries, primarily in the downstream sector, have resulted in a robust set of guidelines and specifications for process safety. These best practices have broad applicability to upstream oil and gas, especially for offshore facilities.
In particular, the pressure relief system is an integral part of upstream design and operation; prevention of an accidental release of toxic, flammable or noxious materials from a production facility requires correct design and construction, safe operation, and proper documentation of this system.
In practice, relief system design and documentation for upstream production facilities and downstream refining or chemical facilities is quite similar. In fact, API RP 75 mirrors the requirements of the United States Department of Labor’s Occupational Safety and Health Administration’s safety standard entitled “Process Safety Management of Highly Hazardous Chemicals”(29 CFR 1910.119)- which is applicable to qualifying onshore facilities (PSM). This paper aims to debunk any notion that upstream oil and gas is fundamentally different by providing comparative data from numerous relief system design studies for upstream and downstream facilities showing similar classes of deficiencies. This paper proposes a basic change in the way relief systems are documented - a requirement in order to comply with 29 CFR 1910.119 and thereby describes a new methodology and a change in documentation to meet OSHA requirements and other industry standards (such as API 520/521, API-RP 75, 14J).
The paper will assist upstream facility personnel to utilize good engineering practice in design and documentation of safety relief systems, to meet both onshore and offshore process safety requirements, and to develop consistent company best practices for process safety management. In addition to the comparative data, the paper will describe a comprehensive equipment based analysis protocol, preparation of documentation sufficient for design, operational, and audit purposes, and discuss maintenance both of the physical system and design data.
