Abstract

Fremgangsmåte for lekkasjedeteksjon i en rørledning, karakterisert ved de føl- gende trinn: å innføre i rørledningen (W) ved en åpning, en fra først løst tilpasset plugg (11) som har i det minste en utvidbar periferi (21), til- passet for oppblåsing ved hjelp av et fleksibelt rør (23), anordning langs lengden av det fleksible rør (23) en søkeranordning (31) for fjerndetektering av posisjonen for pluggen, å tillate pluggen (11) å bli drevet langs rørled- ningen ved en fluidtrykkforskjell, opp- blåsing av pluggen for i hovedsak å blokkere strømmen av væske, å verifisere trykket eller strømforholdene oppstrøms fra pluggen for å detektere en fluidlek- kasje, fJerndetektering av posisjonen for pluggen og relatering av denne til posisjonen av lekkasjen (X).
