API RP 14C-2017 pdf download.Analysis , Design , Installation , and Testing of Safety Systems for Offshore Production Facilities.
Detailed process safety system design is not discussed and should be left to the discretion of the designer as long as the recommended safety functions are properly implemented. Rotating machinery is considered in this document as a unitiz ed process component as it interfaces with the plattorm 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 documen t. Annex A contains a safety analysis for each process component commonly used in a production process , including a checklist of additional criteria for consideration when the component is used in a specific process configuration. 2 Normative References The following referenced documents are indispensable for the application of this documen t. For dated references , only the edition cited applies. For undated references , the latest edition of the referenced document applies (including any addenda/errata).

3.1.2 atmospheric service Operation at gauge pressures between 0.5 ounce psi (0.2 kPa) vacuum and 5 psi (35 kPa) pressure. 3.1.3 backflow Fluid flow in a process component opposite to the normal flow direction. 3.1.4 blowdown valve An automatically operated valve used to vent the pressure from a process station. 3.1.5 boarding shutdown valve BSDV A shutdown valve (SDV) (3.1.68) installed on a production facility that isolates the subsea wellhead flowlines from the production facility. NOTE See Figure 1 . 3.1.6 classified area Any area electrically classified in accordance with API 500 or AP I 505. 3.1.7 containment Any method used on an offshore facility to collect and direct escaped liquid hydrocarbons to a safe location 3.1.8 control cir c uit Electrical , pneumatic hydraulic transmission system (e.g. wiring , tubing , relays) and logic solver (hardware and software) used to connect associated sensors and final elements. 3.1.9 detectable abnormal condition An abnormal operating condition that can be automatically detected. 3.1.10 dir ec t ignition s our ce An exposed surface , flame , or spark at suffici en t temperature and heat capacity to ignite combustibles. 3.1.11 emergency evacuation/ muster station A location where personnel gather in the case of an emergency and develop plans to either contend with the emergency or evacuate. NOTE The location is typically inside or adjacent to the and near the means 01 evacuation such as lileboats. 3.1.12 emerge ncy shutdown system ESD system System of manual stations that initiates facility shutdown when activated. NOTE Act i vat ion 01 the ESD system can al so be init iate d automatically by lire detect ion devices and other salety devices .
3.1 .1 6 facility safety system An arrangement of safety devices and ESSs to affect plattorm shutdow n. NOTE The system can consist 01 a number 01 individ ual process shutdowns and can be actuated by either manual devices or automatic devices sensing detectable abnorma l cond i tions . 3.1 .1 7 facility shutdown The shutting in 01 all process stations 01 a lacility production process and all for the process. 3.1 .1 8 fàil closed valve valve that shifts to the closed position upon loss of the power medi um . 3;1 .1 9 fail open valve A ,v alve that shifts to the open position upon loss of the power medium. 3.1 .20 failsafe A mechanism capable of returning to a safe state in case there is a failure. 3.1.21 failure Improper or operation 01 a device or equipment it em that prevents completion 01 its design lunction or inten t. 3.1 .22 final Part 01 a safety instrumented system that implements the physical action necessary to achieve a safe state. EXAMPLE Examples are valves , switch gear , and motors , including their auxiliary el ements , e. g. a solenoid valve and actuator il involved in the salety instrumented lunction. 3.1 .23 fire detection system A system utilizing pneumatic fusible elements [temperature safety element (TSE)] or various electrical fire detection devices , including flame (USH) , thermal (TSH) , or smoke (YSH) detection devices , installed to detect fires.
