5.2.2.10 Receiving inspection
SSSV system equipment shall be inspected when received.
Upon receipt of the SSSV equipment on location, documentation. e.g. receiving report, operations manual. data sheet, shall be checked to
a) verify that the part number and serial number on the SSSV equipment correspond to those recorded on the accompanying documents.
b) ensure that all visible sealing elements and threads are not damaged, and that all other visible features do not exhibit damage that may Interfere with the SSSV equipment operation.
Prior to installation, the opening and closing hydraulic pressures (or operating loads) shall be verified according to the specific manufacturer’s operating manual. Ensure that the SCSSV will function fail-safe at the planned setting depth before installation by calculation of FSSD in accordance with the manufacturer’s operating manual
It is recommended that SSSV system components be functionally tested pnor to installation. Annex B offers guidelines for performing this process.
5.2.3 System test
5.2.3.1 General
When installed, the SSSV system equipment shall be tested by qualified personnel to ensure proper operation. System evaluation procedures shall include testing procedures, acceptance criteria, and documentation requirements.
5.2.3.2 Surface control system
To assure performance of the surface control system within the design limits, the manufacturer’s/operator’s prescribed operating procedures shall be followed. See Annex C for further recommendations and guidelines on operations.
The surface control system shall be tested at a maximum interval of every six months, with consideration given to no-flow conditions, unless local regulations, conditions and/or documented historical evidence indicate a different testing frequency.
To test the system, operate an ESD valve. The system tests successfully when all SCSSVs close after the prescribed delay
5.2.3.3 SCSSV
The opening and closing hydraulic pressures, mechanical actuation, closure-mechanism integrity and other features shall be verified according to the manufacturer’s operating manual prior to valve installation.
Alter installation of the SCSSV in the well, the SCSSV shall be closed under minimum or no-flow conditions by operation of the surface control system Verification of closure operation may be accomplished by pressure build-up/In-flow lest The SCSSV can be tested for leakage by opening the surface valves to check for flow. The SCSSV is reopened following the procedures in the manufacturer’s operating manuaL
SCSSVs shall be tested by closure-mechanism operation to verity the rate of leakage through the closure mechanism at a maximum interval of every six months unless local regulations, conditions and/or documented historical data indicate a different testing frequency. Leakage rates exceeding 400 cm3lmin (13,5 ozfmin) of liquid or 0,43 m3/min (15 scfm) of test gas shall be cause for test rejection and corrective action shall be taken to meet the requirements of this International Standard, Methods other than volumetric determination of leakage may be used, provided they are verifiable and repeatable. Example procedures for testing of an in situ SCSSV are provided in Annex E, wtich confirm tail-safe operation.
More frequent operation of the SCSSV as dictated by field experience may serve to keep all moving parts free and functioning properly, and aid in early detection of failures.
5.2.3.4 SSCSV
Before installation, SSCSV5 shall be tested by qualified personnel in accordance with the manufacturer’s operating manual to verify mechanical actuation and closure-mechanism pressure integrity. A mechanical device may be used to test the actuation mechanism.
Guidance on sizing of subsurface-controlled safety valves is provided in Annex 0.
TestIng of an SSCSV In the well Is only recommended for those systems designed lot in situ testing.
Installed (non-tubing conveyed) SSCSVs shall be retrieved, inspected, tested, and reset to current well conditions in accordance with the manufacturer’s recommendations at intervals not to exceed 12 months. More frequent inspection as dictated by field experience may be necessary for early detection of service wear or fouling.
Pressure testing of the closure mechanism should be at 1,38 MPa ± 5 % (200 psi ± 5 %) pressure differential. Leakage rates exceeding 400 cm3imin (13,5ozimin) of liquid or 0,43m3/min (l5scfm) of test gas shall be cause for test rejection.
5.2.4 System quality
5.2.4.1 General
This subclause provides minimum quality control requirements to meet this International Standard. All quality control functions shall be controlled by documented instructions, which include acceptance criteria and test results.
5.2.4.2 Personnel qualifications
Au personnel performing installation, redress, testing, and inspection for acceptance shall be qualified In accordance with documented requirements.
Personnel performing visual examinations shall have an annual eye examination, as applicable to the discipline to be performed, in accordance with ISO 9712.
Personnel performing NDE shall be qualified in accordance with ISO 9712. to at least Level II or equivalent. NOTE Far the purposes at these provisions, SNT.TC-IA is equivalent to ISO 9712.
