METHOD AND DEVICE FOR DETECTION, REMOTELY, OF SEALING FAULTS OF A CONDUIT OF TRANSPORT OF A FLUID, IMMERED IN AN AMBIENT FLUID; TRANSPORT CONDUIT COMPRISING THIS DETECTION DEVICE AND METHOD OF CONSTRUCTING SUCH A CONDUCT

摘要

P THE PRESENT INVENTION MAINLY CONCERNS A METHOD AND A DEVICE FOR DETECTION, REMOTELY, OF SEALING FAULTS OF A TRANSPORT CONDUIT OF A FLUID IMMERED IN AN AMBIENT FLUID. / P P THE INVENTION DETECTION METHOD COMPRISES GLOBAL DETECTION MEANS AND MEANS FOR LOCALLY DETECTING THE SEALING DEFECTS OF THE CONDUIT. THE MEANS OF GLOBAL DETECTION ARE CONSISTING OF CONTINUOUS SCANNING OF AN ANNULAR SPACE 11 SURROUNDING THE DRIVING ELEMENTS 17, BY NITROGEN, AND A CONTINUOUS ANALYSIS OF THE EXTRACTED NITROGEN STREAM. LOCAL DETECTION MEANS ARE CONSTITUTED BY PRESSURE SWITCHES DETECTING THE TRANSPORTED FLUID AND LEVEL DETECTORS DETECTING LOCAL AMBIENT FLUID ACCUMULATIONS IN THE ANNULAR SPACE 11. MEANS OF ANALYSIS 28, PRESSURE SWITCHES 23 AND DETECTORS LEVEL 24 ARE RELATED TO ALARM MEANS 30. / P P THE PRESENT INVENTION APPLIES NOTAMALLY TO UNDERWATER FLUE TRANSPORT. / P
