Recommended Practice for Installation, Maintenance and Repair of Surface Safety Valves and Underwater Safety Valves Offshore
Includes all amendments and changes through Errata , September 23, 1996
Published By:American Petroleum Institute (API)
1.1 One of the means of assuring positive wellstream shut-off is the use of the wellhead surface safety valve (SSV) or underwater safety valve (USV). It is imperative that the SSV/USV be mechanically reliable. It should therefore be operated, tested, and maintained in a manner to assure continuously reliable performance.
1.2 The purpose of this recommended practice is to provide guidance for inspecting, installing, operating, maintaining, and repairing SSVs/USVs manufactured according to API Specification 14D. Included are procedures for testing SSVs/USVs.
1.3 This standard was developed as an API recommended practice under the jurisdiction of the API Committee on Standardization of Offshore Safety and Anti-Pollution Equipment (API OSAPE Committee) and was prepared with the guidance of API, the Offshore Operators Committee (OOC), and the Western States Petroleum Association (WSPA).
1.4 The API OSAPE Committee has the following scope: API specifications and recommended practices for safety and anti-pollution equipment and systems used in offshore oil and gas production, giving emphasis when appropriate in such standards to manufacturing, quality assurance, equipment performance, testing, and systems analysis methods.
1.5 For many years, the petroleum industry has devised plans and procedures to provide a safe operating environment and to prevent waste and pollution. These recommended practices for operating SSVs/USVs are based on the accumulation of experiences and plans.
1.6 This recommended practice covers guidelines for inspecting, installing, maintaining, repairing, and operating SSVs/USVs. Nothing in this recommended practice is to be construed as a fixed rule without regard to sound engineering judgment nor is it intended to override applicable federal, state, or local laws.
