Device and method for monitoring of annulus volume in a pipe

摘要

The present invention is related to integrity monitoring of an annulus volume in a pipe. More specifically, the invention is related to an arrangement and a method for determination of annulus free volume of a pipe. The monitoring can as an example be performed by use of a logical unit which controls the annulus testing by use of diffusion or gas feed, and also give input to calculation of the pipe's remaining lifetime. Further, the arrangement can as an example save and present results, allow for user specified settings and set off alarms it critical values are detected.
