Abstract: A method for the removal of debris and other unwanted matter from the bore of a blind tubular line (38) including measuring the length of the bore once it has been cleared. The cleaning and measurement method includes inserting an elongate tube (12) into the bore of the line (38), injecting (12, 14) a compressed gas through the elongate tube (38) and extracting by suction (32) from the end of the line at which the tube enters debris and other unwanted matter from the gap between the tube and the inner wall of the line, attaching a flexible elongate member to a camera insertible in the said bore in such a manner that an end portion of the said member is detected by the said camera when the camera is moved along the said bore, moving the camera and the said member attached thereto along the said bore until the said member is detected by the camera to reach the blind end of the tubular bore, and measuring the length of the said elongate member which has been fed into the tubular line to reach the said blind end.
