3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 9000 and the following apply. 3.1 control line conduit utilized to transmit control signals to SCSSVs 3.2 emergency shutdown system system of stations which, when activated, initiate facility shutdown 3.3 equalizing feature SSSV mechanism which permits the well pressure to bypass the SCSSV closure mechanism 3.4 fail-safe device device which, upon loss of the control medium, automatically shifts to a safe position 3.5 fail-safe setting depth maximum true vertical depth at which an SCSSV can be set and closed under worst-case hydrostatic conditions 3.6 maintenance service operations performed on SSSV system equipment as part of routine operations 3.7 manufacturer principal agent in the design, fabrication and furnishing of original SSSV system equipment 3.8 operating manual publication issued by the manufacturer, which contains detailed data and instructions related to the design, installation, operation and maintenance of SSSV system equipment 3.9 operator user of SSSV system equipment [ISO 10432] 3.10 orifice designed restriction which causes the pressure drop in velocity-type SSCSVs 3.11 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 3.12 qualified part part manufactured under a recognized quality assurance programme and, in the case of replacement, produced to meet or exceed the performance of the original part produced by the original equipment manufacturer (OEM) NOTE ISO 9001 is an example of a recognized quality assurance programme. 3.13 qualified personnel personnel with characteristics or abilities, gained through training and/or experience as measured against established requirements, standards or tests, that enable the individual to perform a required function 3.14 redress any activity involving the replacement of qualified parts (3.12) within the limits described in 5.3.3 3.15 repair any activity beyond the scope of redress 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 3.16 safety valve landing nipple any receptacle containing a profile designed for the installation of an SSSV lock mandrel NOTE It may be ported for communication to an outside source for SSSV operation. 3.17 safety valve lock mandrel retention device used for SSSV equipment 3.18 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 3.19 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 3.20 SSSV system equipment components which include the surface-control system (3.2.4), control line (3.1), SSSV (3.23), safety valve lock (3.17), safety valve landing nipple (3.16), flow couplings and other downhole control components 3.21 surface-controlled subsurface safety valve SCSSV SSSV controlled from the surface by hydraulic, electrical, mechanical or other means 3.22 subsurface-controlled subsurface safety valve SSCSV SSSV actuated by the characteristics of the well itself NOTE These devices are usually actuated by the differential pressure through the SSCSV (velocity type) or by tubing pressure at the SSCSV (high or low pressure type). 3.23 subsurface safety valve SSSV device whose design function is to prevent uncontrolled well flow when closed NOTE These devices can be installed and retrieved by wireline or pump-down methods (wireline-retrievable) or be an integral part of the tubing string (tubing-retrievable).
