A method of monitoring the performance of a pipe containing a pressurised fluid, the pipe including at least one current zone and singular zones. The method includes: the static monitoring of a pre-determined number of singular zones, in order to obtain circumferential dilatation information; and the calculation of the effective stiffness k(ti) of the pipe and of the measured residual steel section (As(ti) of same, using the above-mentioned circumferential dilatation information. The method can also include the dynamic monitoring of the pipe, in order to obtain information relating to the natural vibration frequencies and modes thereof.
