Abstract
A method and apparatus are disclosed for testing one or more layers of a flexible pipe. The method includes the steps of applying a test cycle to a flexible pipe and simultaneously applying the same test cycle to a tubular test layer connected in an in-line configuration with the flexible pipe.
Claims16
A method of probing a layer of a flexible pipe, comprising the steps of:
- securing a tubular test layer and a flexible pipe together in an in-line configuration;
- applying at least a test cycle to the flexible pipe, wherein the test cycle comprises the step of applying a pressure to the layer using a pressurising medium which is at least 1.5 times a design pressure of the flexible pipe for a predetermined period of time;
- and
- simultaneously applying the test cycle to the tubular test layer;
- wherein said steps of securing a tubular test layer and a flexible pipe together in an in-line configuration, applying at least a test cycle to the flexible pipe and simultaneously applying the test cycle to the tubular test layer are performed prior to utilisation of the flexible pipe.

A method of probing a layer of a flexible pipe, comprising the steps of:
- securing a tubular conditioning layer and a flexible pipe together in an in-line configuration;
- applying at least a conditioning cycle to the flexible pipe, wherein the conditioning cycle comprises the step of applying a pressure to the layer using a heated pressurising medium;
- and
- simultaneously applying the conditioning cycle to the tubular conditioning layer
- wherein said steps of securing a tubular conditioning layer and a flexible pipe together in an in-line configuration, applying at least a conditioning cycle to the flexible pipe and simultaneously applying the conditioning cycle to the tubular conditioning layer are performed prior to utilisation of the flexible pipe.
