Abstract:
1. A method of testing integrity of a portion of flexible pipe body for transporting production fluids from a sub-sea location, prior to installation and use comprising the steps of: providing a flexible pipe body that is suitable for forming a riser or flowline formed as a composite structure of layered materials, the layers including an internal polymer sheath, a pressure armour layer, and an inner sealing layer, via at least one port in an end fitting assembly in which an end of a portion of flexible pipe body is terminated, introducing test fluid under pressure at said port, ceasing the introduction of test fluid at said port, monitoring at least one parameter associated with an annulus region disposed between an outer surface of the internal polymer sheath and an inner surface of the inner sealing layer of said flexible pipe body where the inner surface of the inner sealing layer is spaced radially outwardly from and extends co-axially over the outer surface of the internal polymer sheath, said annulus region being connected to said port by a connecting passageway, and evacuating the test fluid prior to installation and use of the flexible pipe body.
