`the GOT lists more than one definition for a term, the
`definition applicable to API Specification 6A shall apply.
`Annulus Seal Assembly —- A mechanism which pro-
`vides pressure isolation between each casing hanger

`bore surfaces during drilling or workover operations.
`Check Valve — A device designed to restrict flow in
`one direction.
`
`Completion Riser — A riser that is designed to fit

`and may also be suitable for connection to the tree upper
`connection for use as a means for running the tree or for
`use as a workover riser (see workover riser).
`
`Concentric Bore Tubing Hanger —-A tubing hanger
`where the production bore is concentric with the OD. of
`the hanger, normally requiring no orientation during
`installation.
`
`Conductor Housing -— The top of the first casing.
`string which forms the basic foundation of the subsea
`wellhead and provides attachments for guidance struc-
`tures.
`
`Corrosion Cap — A cap placed over the wellhead to
`protect it from contamination by debris, marine growth,
`or corrosion during temporary abandonment of the well.
`Corrosion Resistant Alloys (CI-IA) — Nonferrous
`alloys where any one or the sum of the specified amount
`of the following alloy elements exceeds 50%: titanium,
`nickel, cobalt, chromium, and molybdenum.
`Corrosion Resistant Materials (CRM) — Ferrous
`or nonferrous alloys which are more corrosion resistant
`than low alloy steels. This term includes CRA’s, duplex,
`and stainless steels.
`"
`
`Depth Rating —— The maximum rated working depth
`of a piece of equipment at a given set of operating
`conditions.
`
`Downstream -— Direction of movement away from
`the reservoir.
`
`Sealing tubular member that pro-
`Extension Sub
`vides tree bore continuity between adjacent tree compo-
`nents.

`
`production (iniection) or annulus flow path and is not
`in the vertical bore of the tree. Each side outlet for
`production (injection) and annulus flow path of the
`subsea tree shall have at least one wing valve.
`922.1d Swab Closures. Any vertical bore that
`passes through the subsea tree assembly, which could
`be used in workover operations, shall be equipped
`with at least one pressure controlling (swab) closure
`located above the uppermost tree side outlet. Swab
`closures may be caps, stabs, tubing plugs, or valves.
`Removal or opening of the swab closure shall not
`result in any diametrical restriction through the ver-
`tical bore of the subsea tree.
`Swab valves may be either manual or hydraulically
`operated.
`If no other hydraulically operated fail-closed valve
`is in a vertical annulus bore ofthe tree, then the swab
`closure for that bore shall be a hydraulically oper-
`ated fail-closed valve.
`
`922.19 Crossover Valves. A crossover valve is an
`optional valve that, when opened, allows communica-
`tion between two tree paths that are normally iso-
`lated. Crossover valves are not required on APl- Speci-
`fication 17D equipment.
`922.1f Tree Assembly Pressure Closures. The
`subsea tree assembly shall meet the pressure closure
`requirements of this section.
`NOTE: This specification is only concerned with th
`pressure closure requirements contained within the
`subsea tree assembly. Other industry recognized pres-
`sure closures contained in the total system such as ,
`downhole SCSSV’s or flowline values are beyond the ’
`scope of this specification. It is not intended that the
`multiple pressure closure requirements of the subseo
`tree assembly replace the need for other system pres-
`sure closures.
`
`922.lf(1) Production (Injection) Flow Paths.
`There shall he at least two hydraulically operated
`fail-closed valves in the production (injection) flow
`stream of the subsea tree.
`
`9 In the case of a subsea tree with only one hydrau-
`lically operated fail-closed master valve, then at
`least one wing valve shall also be a hydraulically
`operated fail-closed valve.
`0 In the case ofa subsea tree with two hydraulically
`operated fail-closed master valves, then the wing
`valves may be either manual or hydraulically
`operated.
`Figure 9223 illustrates some of the combinations
`of master and wing valving which meet the subsea
`tree pressure closure criteria ofthis section and the
`requirements of Sections 922.1b thru 922.1d ofthis
`specification.
`922.1f(2) Annulus Flow Paths. All annulus
`paths of the tree or tubing hanger spool shall have
`at least two pressure controlling closures, one of
`which shall be a hydraulically operated fail-closed‘
`valve. Figure 922.4 illpstrates some ofthe combina-
`tions of annulus valvxng which meet the pressure
`
`closure criteria of this section and the require-
`ments of Sections 9221:: and 922.1d of this specifi-
`cation.
`
`922.1f(3) Production and Annulus Bore Pen-
`etrations. Any penetrations into the production
`(injection) flow stream of the subsea tree shall be
`made above the lowest master valve. Flanges, clamp
`hubs or other end connections meeting the require-
`ments of Sections 901, 902, 904, 905 and 906 of this
`specification, as applicable, shall be used to provide
`connections for the penetrations to the tree.
`There shall be at least two fail-closed pressure
`, closures, one of which must be hydraulically oper-
`ated fail-closed, between the wellhead and any pen- .
`etration leading into either the production (injec-
`tion) or annulus path of the_tree or tubing spool.
`Flow closed check valves are acceptable as fail-
`closed closures for monitoring or chemical injection
`penetration lines that are one-inch (25.4 mm) nomi-
`nal diameter or smaller.
`Devices that terminate directly on the tree such
`as transducers do not require penetration valving,
`provided there is a pressure closure between the
`tree bore and the environment. These devices shall
`comply with Section 606 of this specification, if
`there is no hydraulically operated fail-closed valve
`between the penetration and the wellhead.
`~’Figure 922.5 illustrates various combinations of
`penetration valving which meets the requirements
`of this section.
`922.1114) Downhole SafetyValve ControlLine:'
`Penetrations. At least onepressure controlling
`closure shall be used at all downhole safety valve
`control line penetrations that pass through either
`the tree or tubing spool. Manual valves are accept-'
`able closure . devices.
`'
`Any remotely operated closure device used in the
`downhole safety valve control line circuit shall be
`designed such that it does not interfere with the
`closure of the downhole safety valve.
`Check valves shall not he used anywhere in the
`downhole safety valve control line circuit.
`The right side of Figure 922.6 illustrates typical
`subsee tree valving for SCSSV circuits that meets
`the requirements of this section.
`922.1f(5) Downholc Chemical Injection Line
`Penetrations. The subsea tree assembly shall pro-
`vide for two fail-closed valves in all chemical injec-
`tion lines which pass through the tubing hanger.
`« Flow-closed check valves are acceptable as one of
`the fail-closed valves for line sizes of one-inch (25.4
`mm) nominal diameter or smaller. At least one of
`the fail-closed valves shall be a hydraulically oper-
`ated fail-closed valve. Flanges, clamp hubs or other
`end connectors meeting the requirements of Sec-
`tions 901, 902, 904, 905, and 906, as applicable, of
`this specification shall be used to provide connec-
`tions for the penetrations to the tree. The left side
`ofFigure 922.6 illustrates typical subsea tree valving
`that meets the requirements of this section.
