METHOD FOR PERFORMING WORK ON UNDERWATER PIPES

摘要

An apparatus for underwater pipes comprising an ultrasound emitting system and at least one ultrasound receiving transducer is lowered into he marine environment. During an inspection phase, an ultrasound inspection source of the ultrasound emitting system and the receiving transducer are disposed on each side of the pipe. The inspection source is activated, and an ultrasound signal captured by the receiving transducer is recorded. In response to the observation of an anomaly in the ultrasound signal captured by the receiving transducer, a power source of the ultrasound emitting system is then coupled to the pipe at the aforementioned location, and the power source is activated in order to destroy the obstruction.

1. A method for performing work on an underwater pipe, comprising a phase of lowering into the marine environment an apparatus comprising an ultrasound emitting system and at least one ultrasound receiving transducer, an inspection phase along the pipe using the lowered apparatus then, when the inspection phase shows a condition for locating an obstruction at a location along the pipe, a destruction phase of the obstruction at said location using the lowered apparatus,the inspection phase comprising:arranging an ultrasound inspection source of the ultrasound emitting system and the receiving transducer on either side of the pipe;activating the ultrasound inspection source and recording an ultrasound signal captured by the receiving transducer: anddetecting the condition for locating an obstruction at the location along the pipe wherein are arranged the inspection source and the receiving transducer in response to the observation of an anomaly in the ultrasound signal captured by the receiving transducer at the location, and the destruction phase comprising:coupling a power source of the ultrasound emitting system to the pipe at said location; andactivating the power source in order to destroy the obstruction.
