Abstract

A method for inspecting a pipeline (1), comprising: a. introducing a transport unit (16) with a sealing element (28) into the pipeline, such that the sealing element forms a fluid sealing with an inner wall (22) of the pipeline; b. introducing a measuring unit (18) into the pipeline for inspecting the pipeline; c. mechanically interconnecting the measuring unit and the transport unit; d. creating a fluid pressure difference in the pipeline between the two sides of the sealing element, so that as a result of the pressure difference the transport unit with the measuring unit is transported in a first direction (60) through the pipeline; and e. inspecting the wall of the pipeline with the measuring unit.
