Claim:
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, upon detecting a condition for locating an obstruction at a location along the pipe in the inspection phase, 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 at least one ultrasound receiving transducer on either side of the pipe; activating the ultrasound inspection source and recording an ultrasound signal captured by the at least one ultrasound receiving transducer; and detecting the condition for locating the obstruction at the location along the pipe wherein are arranged the inspection source and the at least one ultrasound receiving transducer in response to the observation of an anomaly in the ultrasound signal captured by the at least one ultrasound 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; and activating the power source in order to destroy the obstruction,
