a) Near wellheads or other areas of elevated temperature;
b) Immediately downstream of pumping/compressor stations;
C) Where separation of fluids is known to occur.
Test spools should be exposed to the same pressures, stresses, and fluid conveyance conditions as those existing in the spoolable pipe, if practicable.
The test spool or sample trap, for polymer coupon monitoring of production fluid, should be located nearest the highest operating temperature or else the temperature at the test spools should be controlled to a temperature at least as high. Alternatively, although less ideal, samples can be analyzed knowing their conditions (pressure, temperature) with the aging model and the aging associated with the elevated temperature conditions may be extrapolated. If erosion is known to be an issue within the pipeline, the test spools should be designed to reflect the operating MBR of the spoolable pipe in service.
Destructive and non-destructive test methods relevant to the materials and design should be used to evaluate the test spools based on manufacturers recommendations.
9.6 Monitoring Methods
In some spoolable pipe designs, the annulus between the liner and outer cover may require venting in service to relieve permeated gases. The manufacturer should determine whether the annulus contains sufficient free volume and communication between end-fittings to allow annulus pressure testing or monitoring as a form of integrity assessment. Annulus pressure testing can confirm that the outer cover is intact and may be performed post-installation prior to line commissioning, at regular intervals during operation, or both.
The manufacturer should provide guidance on the following items:
a) Recommended annulus testing method (vacuum or positive pressure);
b) Acceptable gases for positive pressure annulus testing;
c) Maximum allowable annulus test pressure to prevent liner collapse or outer cover rupture, considering the effects of manufacturing tolerances, pipe ovality, temperature, and outer cover dimensional acceptance criteria;
d) Expected volume of test gas required to raise the annulus pressure to the test pressure (determined theoretically or via testing);
e) Recommended hold period at the annulus test pressure;
f) Annulus test acceptance criteria;
g) Remedial actions in the event of unacceptable test results;
h) Recommended training or certification for annulus testing personnel.
The annulus testing equipment should include a gas-relief valve designed to prevent unintended overpressurization of the annulus.
In some cases, permanent monitoring systems may be connected to the annulus vent ports as a method of real-time or periodic integrity assessment. These systems may include pressure, temperature, flow rate, or gas composition monitonng. The intent of annulus monitoring may be to detect liner breach or outer cover damage in-service, or to confirm that the annulus conditions and permeation rates are as expected.
