API RP 14C: 2017 [paper]

This document presents provisions for designing, installing, and testing both process safety and non-marine emergency support systems on an offshore production facility. The basic concepts of a facility safety system are discussed and protection methods and requirements of the system are outlined. For the purposes of this document, all process components from the surface wellhead and/or topside boarding valve are considered. See API 17V for guidance safety systems for subsea equipment.

This document illustrates how system analysis methods can be used to determine safety requirements to protect common process components. This document also includes:

a) a method to document and verify process safety system functions (i.e., SAFE chart);
b) design guidance for ancillary systems such as pneumatic supply systems and liquid containment systems;
c) a uniform method of identifying and symbolizing safety devices;
d) procedures for testing common safety devices with recommendations for test data and acceptable test tolerances.
