Method and device for localizing anomalies located inside an immersed hollow structure
First Claim
1. A method for external localization of anomalies located in an immersed hollow structure, which anomalies were detected beforehand by a device moving inside said immersed hollow structure, and positioned by counting from an origin, marks located at regular intervals accessible from the inside and outside of said immersed hollow structure, consisting of:
- a. defining by counting, from the same aforesaid origin, a mark accessible on the outside of the immersed hollow structure, b. positioning a transponder module on the aforesaid mark, c. identifying the transponder module by an identification code, d. determining the number of marks separating said anomalies and said identified transponder module.

Abstract
A method for externally locating anomalies located inside an immersed hollow structure (PL), wherein said anomalies are previously detected by a device (RTE) moving inside said immersed hollow structure, and are positioned by counting a series of reference marks from an origin, said reference marks being located at regular intervals and being accessible from the inside and outside of said immersed hollow structure. The inventive method consists in defining by means of counting a reference mark, starting from said origin, which is accessible from the outside of the immersed hollow structure; positioning a transponder module (T) on said reference mark; identifying the transponder module (T) by an I.D. code; determining the number of reference marks separating the anomalies and the identified transponder module (T).
