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.

Abstract: A method and device for stabilizing a conductor (4) in a submerged conductor guide (6) on an offshore installation (8) where an annulus (2) is present between the conductor (4) and the conductor guide (6), wherein the method includes:—establishing any misalignment between the conductor (4) and the conductor guide (6);—producing a support body (1) that is adapted to said misalignment and where the support body (1) is designed to fill a sector of the annulus (2); and—moving the support body (1) axially into the annulus (2) between the conductor (4) and the conductor guide (6).
