A safety analysis examines every process component on the facility to determine which undesirable events could be associated with each component, which safety devices are required for the protection of the ro, and what responses the safety devices must make to ensure adequate protection.

By studying each of these undesirable events, information can be gained to make a facility safe. Identifying all the components that handle hydrocarbons in a production facility would be overwhelming.

Recommended methods for safety analysis

A graphic symbol represents each safety device. Process variables allow movement of the fluids through the process aoi while simultaneously achieving the degree of separation required for sales or water disposal.

SATs consider each undesirable event that could possibly affect the component and then, for each undesirable event, lists associated causes, detectable abnormal conditions, and required locations for api rp 14c the protection devices. Abnormal conditions api rp 14c are not dealt with quickly can escalate into worst-case scenarios. Examples of equipment failure or malfunction are chokes that become enlarged through contact with excessive sand in the flow stream, dump valves that hang open or stay a;i, and regulators or controllers that change adjustment because of vibration.

Recommended methods for safety analysis –

Human error also can occur if the operator monitored the level api rp 14c but forgot api rp 14c check to see if the newly repaired dump valve was operating properly.

Information about the detectable abnormal condition provides a tool for better monitoring and provides information about which types of safety devices can be used to warn of an impending undesirable event. The process was similar to that used to identify the ten process components. When read vertically, the information pertains not only to the end devices affected by appi safety device, but to their function as well e.

Use this section to list papers in OnePetro that a reader who wants to learn api rp 14c should definitely read. SAFE charts are used to ensure that the facility is as fully protected as it should be and also can be used as a troubleshooting tool. Abnormal conditions do not always develop into a serious consequence, but it could happen. The third and usually final part of the name refers to either the device appi i.

If fully protected when analyzed standing alone, the analysis will be valid for that component in any configuration. For example, the pressure on a flowline will fluctuate from reading to reading within a specified period of time api rp 14c.

By examining each component as if it was standing alone, an adequate degree of protection can be determined for each particular component. However, if the maximum allowable working pressure MAWP of the flowline and associated equipment is greater than the maximum shut-in tubing pressure of the well, the component is already protected and the device is not needed.

If the undesirable-event stage is reached, there are api rp 14c ways of preventing or lessening the chance of the occurrence of worst-case consequences e. Verifying that each and every component is protected without considering other components ensures the api rp 14c degree of consistent protection. The purpose of a safety analysis is to identify undesirable events that might pose api rp 14c threat to safety and define reliable protection measures that will prevent such events or minimize their effects should they occur.

SACs provide a guideline for eliminating redundant devices while maintaining the required level of protection. A SAT-required safety device also no longer may be required if the same degree of protection is provided by another device api rp 14c elsewhere.

A liquid level above or below the point at which the dump valve opens or closes is an abnormal condition. To address this problem, the API mandates a api rp 14c means of protecting the facility. Process components function in the same manner regardless of specific facility design.

For example, the liquid level within a vessel can fluctuate from the bottom of the vessel empty to the api rp 14c full.

As these devices became more common, industry standards were established, such as:. Offshore platforms have melted to the water line because of released api rp 14c, as occurred in the Piper Alpha incident in the North Sea in the summer of Devices respond to one of the four major variables. A safety analysis ties these two things together and is a tool for ensuring that a facility is protected fully.

When components are assembled into a system, some devices can be eliminated. The main purpose of the SSS is to api rp 14c the initial release of hydrocarbons and to shut in additional flow of the hydrocarbons already released.
