1.2 SCOPE
This document presents recommendations for designing, installing, and testing a basic surface safety system on an off- shore production platform. The basic concepts of a platform safety system are discussed and protection methods and requirements of the system are outlined. This recommended practice illustrates how system analysis methods can be used to determine safety requirements to pro- tect any process component. Actual analyses of the principal components are developed in such a manner that the require- ments determined will be applicable whenever the compo- nent is used in the process. The safety requirements of the individual process components may then be integrated into a complete platform safety system. The analysis procedures include a method to document and verify system integrity. A uniform method of identifying and symbolizing safety devices is presented and the analysis method is exemplified by a sample process system. In addition to the basic surface safety system, this recom- mended practice covers ancillary systems such as pneumatic supply and liquid containment. Procedures for testing com- mon safety devices are presented with recommendations for test data and acceptable test tolerances.This recommended practice emphasizes pneumatic sys- tems since they are the most commonly used; however, the same principles and procedures are applicable to hydraulic and electrical systems and to systems incorporating two or more control media. Instrumentation logic circuits are not discussed since these should be left to the discretion of the designer as long as the recommended safety functions are accomplished. Rotating machinery is considered in this rec- ommended practice as a unitized process component as it interfaces with the platform safety system. When rotating machinery (such as a pump or compressor) installed as a unit consists of several process components, each component can be analyzed as prescribed in this recommended practice.
1.3 ORGANIZATION OF TECHNICAL CONTENT
The technical content of this recommended practice is arranged as follows: a. Section 2: Recommended standard symbols and abbrevia- tions for safety device and process component identification. b. Section 3: The general purpose, functional requirements, and basic premises of platform safety system analysis and design. c. Section 4: A detailed discussion of recommended safety analysis techniques, the concepts of protection from which they were developed, and a step-by-step procedure for ana- lyzing and establishing design criteria for a basic platform safety system. d. Appendix A: A safety analysis for each process compo- nent commonly used in a production process, including a checklist of additional criteria that should be considered when the component is used in a specific process configura- tion. e. Appendix B: A sample Safety Analysis Table (SAT), a composite Safety Analysis Checklist (SAC), and a sample Safety Analysis Function Evaluation (SAFE) Chart. f. Appendix C: A discussion of supporting systems that per- form specific safety functions common to the entire platform. g. Appendix D: Testing procedures and reporting methods for the accumulation of safety system test data that can be used for operational analysis, and reports that may be required by regulatory agencies.
