Title (EN) PIG TRACKING BY UNMANNED SUBMARINE
(FR) SUIVI DE RACLEUR PAR SUBMERSIBLE INHABITÉ
Abstract: front page image
(EN)The present disclosure provides for a pig tracking and locating system that is able to pinpoint the exact location of a pig so that if the pig becomes stuck, it can be more efficiently located and retrieved without excessive searching. A representative system includes an unmanned underwater vehicle that travels with or very near the pig as it progresses through a pipeline, and gathers and stores information transmitted by the pig. This information may include location data that can be transmitted in the event the pig becomes stuck.
(FR)La présente invention concerne un système de suivi et de localisation de racleur pouvant identifier la position exacte d'un racleur de sorte que, en cas de blocage du racleur, il puisse être localisé et récupéré de manière plus efficace sans recherche excessive. Un système représentatif comprend un véhicule sous-marin inhabité se déplaçant avec le racleur ou tout près de ce dernier lorsque il avance au long d'un pipeline afin de collecter et de stocker les informations transmises par le racleur. Ces informations peuvent comprendre des données de localisation pouvant être transmises en cas de blocage du racleur.
