3 Terms, Definitions, Acronyms, and Abbreviations 3.1 Terms and Definitions For the purposes of this document, the terms and definitions given in ISO 9000 and the following apply. 3.1.1 alternate technology SSSVs Designs such as but not limited to pressure charged systems, multiple hydraulic systems, indirect connection of the operator to the closure opening device, electric/electronically operated/induced activators, and control systems that include electrical and electronic signaling systems. 3.1.2 ambient-type valve SSSV that is designed to close when tubing pressure drops below a pre-set level. 3.1.3 control line Conduit utilized to transmit control signals to SCSSVs. 3.1.4 control system Device or set of devices used to manage, command, direct, or regulate the behavior of the safety valve under normal operation and fail-safe conditions. 3.1.5 emergency shutdown system System of stations which, when activated, initiate facility shutdown. 3.1.6 end sub End component which provides connection between the tubing-retrievable safety valve (TRSV) and the tubing string and does not affect the functional operations of a TRSV. 3.1.7 equalizing feature Mechanism which, when activated, permits the well pressure to bypass the SCSSV closure mechanism for the purposes of re-opening the SSSV. 3.1.8 fail-safe device Device which, upon loss of the control signal, automatically shifts to a safe position. 3.1.9 fail-safe setting depth Maximum true vertical depth at which an SCSSV can be installed and will close under worst-case hydrostatic conditions. 3.1.10 maintenance Service operations performed on SSSV system equipment as part of routine operations.
3.1.11 manufacturer Principal agent in the design, fabrication, and furnishing of original SSSV system equipment. 3.1.12 operating manual Publication issued by the supplier/manufacturer which contains detailed data and instructions related to the installation, operation and maintenance of equipment. 3.1.13 operator User of SSSV system equipment. 3.1.14 orifice (bean) Designed restriction which causes the pressure drop in velocity-type SSCSVs. 3.1.15 packaging Enclosure(s) of sufficient structural integrity to protect contents from damage or contamination, including impacts and environmental conditions encountered during the various phases of transport. 3.1.16 qualified part Part manufactured under a recognized quality assurance program to meet the design and performance of the original part. NOTE ISO 9001, API Spec Q1, and ISO TS29001 are examples of a recognized quality assurance program. 3.1.17 qualified person Individual or individuals with characteristics or abilities gained through training or experience or both, as measured against established requirements, such as standards or tests that enable the individual to perform a required function. 3.1.18 rated working pressure The lesser of: a) the SSSV internal pressure rating; or b) the differential rating with the valve closed. 3.1.19 redress Any activity involving the replacement of qualified parts (3.1.16) within the limits described in Section 7. 3.1.20 repair Any activity beyond the scope of redress (3.1.19) that includes disassembly, re-assembly, and testing with or without the replacement of qualified parts and may include machining, welding, heat-treating, or other manufacturing operations, that restores the equipment to its original performance.
3.1.21 safety valve landing nipple SVLN Any receptacle containing a profile designed for the installation of an SSSV lock mandrel. NOTE SVLN may be ported for communication to an outside source for SSSV operation. 3.1.22 safety valve lock mandrel Retention device used for SSSV equipment. 3.1.23 secondary tool Tools and other equipment used with subsurface safety valves to perform a secondary function(s) or provide another intended design function. NOTE Secondary tools may include communication, exercise, permanent lock open, temporary lock open, or other tools. 3.1.24 self-equalizing feature SCSSV mechanism which, on initiation of opening sequence of the SSSV, permits the well pressure to automatically bypass the SCSSV closure mechanism. 3.1.25 storage Act of retaining SSSV system equipment without damage or contamination, after processing is completed and prior to or after field use, including the transport process. 3.1.26 SSSV system equipment Components which include the control system (3.1.4), control line (3.1.3), SSSV (3.1.30), safety valve lock mandrel (3.1.22), safety valve landing nipple (3.1.21), flow couplings, secondary tools (3.1.23) and other related downhole control components. 3.1.27 surface-controlled subsurface safety valve SCSSV Normally closed SSSV controlled from the surface by hydraulic, electrical, mechanical, or other means. NOTE A normally closed SCSSV requires a signal to open. Upon loss of that signal, the valve closes.
