Relief valves and relief api rp 14c. Devices respond to one of the four major variables. Safety devices and safety systems are added to prevent undesirable events and they provide the last chance to prevent worst-case consequences from occurring.

Location data provide information on where the safety devices must be positioned for the most effective protection. The major causes of abnormal conditions are equipment failure or malfunction and human error. Verifying that each and every component is protected without considering other components ensures the greatest degree of consistent protection. Maintaining normal operating ranges requires normal process flow.

Abnormal conditions do not always develop api rp 14c a serious consequence, but it could happen.

The SSS incorporates various sensing devices. Knowing about the possible effects of each undesirable event allows for a more rapid or more appropriate response to the undesirable event. RP 14C [1] does an excellent job of describing this information. SAFE charts are used to ensure that the facility is as fully protected as it api rp 14c be and also can be used as a troubleshooting tool.

Regardless of what a piece of equipment is called, it can be described as one of the following ten process components:. Once the variables exceed their normal ranges, safety devices respond to keep the variables from getting further out of range. Concise, easy-to-audit documentation Minimized subjective decisions Consistent results This page explains the basic api rp 14c of protection used in the analysis, discusses the methods of analyzing the process, api rp 14c establishes design criteria for an integrated safety system.

Potential threats to safety are identified through proven hazards-analysis techniques that have been adapted to hydrocarbon-production processes. The pneumatic supply system provides the power to operate most 14d the other systems.

If fully protected when analyzed standing alone, the analysis will be valid for that component in any configuration.

Chokes and controllers keep the variables within their normal ranges. RP 14C [1] provides an analysis technique to identify potential abnormal conditions and api rp 14c them from occurring.

The end device diverts or shuts off flow, sounds an alarm, or takes some other corrective action. Whenever hydrocarbons are api rp 14c in a process component, each of the four main process variables take on some value. They include end devices and auxiliary devices, which are important not only to the system itself but also to the safety of the facility. The third and usually final part of the name refers to either the device itself i.

If api rp 14c component is protected, the system will be protected.

SATs consider each undesirable event that could possibly affect the component 114c then, for each undesirable event, lists associated causes, detectable abnormal conditions, and required locations for installing the protection devices.

Within each process component, each variable has a normal operating range api rp 14c of having a single normal value.

It is important to realize that when api rp 14c device can be eliminated, the device is eliminated and not the required level of protection. For example, if the api rp 14c within a component were to become too high, a component could rupture; a pressure too low within a component could indicate a leak. By studying each of these undesirable events, information can be gained to make a facility safe.

However, the point is that if a variable exceeds its normal operating range at all, it could continue to escalate with potentially disastrous results.

The May Exxon Valdez incident is a prime example of the attention drawn to and the expenses involved with hydrocarbon pollution in navigable waterways. SAFE charts are used to evaluate the function of each safety device and to document precisely what each safety api rp 14c does. The ESS is a major part of those backup efforts.

Recommended methods for safety analysis –

At each stage, action can be taken to keep the main process variables from resulting in worst-case consequences. The following issues are key points about undesirable events. Hydrocarbon zpi alone are often sufficient to cause injury to personnel e.

When this is done for every api rp 14c on the facility, the entire facility will be adequately protected. According to RP 14C[1] serious consequences usually are preceded by some abnormal condition. Neither SATs nor SACs indicate what the devices do or how the devices on one component relate to the devices on another component. Every process component fp be grouped under one of the 10 process components listed in RP api rp 14c[1] and process-related causes of injury, pollution, and damage can be grouped under one pr the eight undesirable events.

Two levels of protection will always be required. Refer to RP 14Cparagraph 4.

Recommended methods for safety analysis

The api rp 14c concern with the four main process variables is that their sensing devices, which api rp 14c to conditions outside normal ranges, have enough time to respond before problems appi. The entire production process is covered, and a step-by-step summary for performing a safety analysis is provided. On average, process variables are found within their normal operating ranges, but horns do go off and shut-ins do occur.
