The current invention relates to a method and apparatus for assessing the condition of a pipeline and also predicting the future rate of deterioration and/or possible failure of the pipeline. The method includes the steps of selecting at least one portion of the pipeline for which the prediction is to be made and, for that portion, monitoring or inspecting and assessing the condition of the pipeline wall, and typically also assessing the condition of any coating of the pipeline at said portion as well as the condition of the soil adjacent the pipeline. The measurement is performed along the length of the portion and preferably around the circumference of the pipeline at said portion. Data is collected for each cell of a grid which represents the said portion and on the basis of the measured data and, selectively, previous data and or reference data, an accurate prediction can be made as to the future condition of the pipeline and also identify potential future problems or required remedial works.
A method for detecting a condition of a length of pipeline, said method comprising the steps of:
A method of testing the condition of a pipeline, said method comprising the steps of determining a portion of the pipeline to be used as a sample to be tested, performing at least one test to determine a condition of the same wherein, if the number of defects detected is below a predetermined level, the condition of the pipeline is deemed to be acceptable and, if above the predetermined level, further testing of the pipeline is performed.
Apparatus for the detection of at least one characteristic of a pipeline, said apparatus comprising:
Apparatus for detecting the condition of a portion of a pipeline wall, said apparatus including a ground penetrating radar device which is movable along a surface of the wall, said device transmitting signals which can be processed to indicate a depth of the wall surface with respect to a predetermined datum thickness value.
