Abstract

A method is provided for measurement of the thickness of any deposit of material on the inner wall of a pipeline at least partly filled with a medium including hydrocarbons, the medium being for instance oil or natural gas, wherein the method includes: projecting infrared light onto the inner wall of the pipeline along a line corresponding to the intersection between the inner wall of the pipeline and a cross-sectional plane of the pipeline; registering an image of the infrared light projected on the inner wall of the pipeline; and determining the thickness of any deposit of material on the inner wall of the pipeline based on the registered image.
