Title (EN) UNDERWATER PIPELINE INSPECTION CRAWLER
(FR) VÉHICULE D’EXPLORATION D'INSPECTION DE PIPELINE SOUS-MARIN
Abstract:
(EN) A system for underwater inspection including an inspection crawler (702) is provided wherein the inspection crawler (702) includes a housing (704) having first and second sides, a power source, a controller, an inspection tool, at least two pairs of driving wheels, and a moveable center of gravity, and a method for traversing a weld joint with the inspection crawler having a moving mass 734), wherein the crawler is parked proximate to the joint (138), and the mass is slid along a slide rail (736) to the second end of the crawler distal to the joint. The first end of the crawler is then propelled over the joint and the mass is slid to the center of the crawler. A center portion of the crawler is then propelled over the joint and the mass is slid to the first end of the crawler. The second end of the crawler is then propelled over the joint.
(FR) L'invention concerne un système d'inspection sous-marine comprenant un véhicule d’exploration d'inspection (702), le véhicule d’exploration d'inspection (702) comprenant un boîtier (704) disposant de premier et second côtés, une source d'alimentation, un dispositif de commande, un outil d'inspection, au moins deux paires de roues d'entraînement, et un centre de gravité mobile, et un procédé permettant la traversée d’un joint soudé à l’aide du véhicule d’exploration d'inspection disposant d'une masse mobile 734), le véhicule d’exploration étant stationné à proximité de la soudure (138), et la masse étant glissée le long d'un rail de coulissement (736) vers la seconde extrémité du véhicule d’exploration, distale par rapport à la soudure. La première extrémité du véhicule d’exploration est ensuite propulsée sur la soudure et la masse est glissée vers le centre du véhicule d’exploration. Une partie centrale du véhicule d’exploration est ensuite propulsée sur la soudure et la masse est glissée vers la première extrémité du véhicule d’exploration. La seconde extrémité du véhicule d’exploration est ensuite propulsée sur la soudure.
