Sammendrag
The quality of static mechanical systems’ integrity control process on aging oil & gas
production and process plants is depending upon the accuracy of the condition
monitoring data. The accurate interpretation of the data significantly aids for making
right decision at the right time on right location.
However, it is observed anomalies on the historical in‐service inspection data
records pertaining to most of aging plants under the study. Such anomalies result
sub‐optimal inspection decisions and jeopardizes quality of an in‐service inspection
program.
The uncertainties of condition monitoring data have been discussed in the literature
and industrial community over the years. Number of approaches has been proposed
to address various challenges pertaining to uncertainties present in the in‐service
inspection data. This thesis investigates the anomalies on data, and further suggests
an empirical approach for quantifying the reliability of condition monitoring data to
estimate the level of anomalies presents in the in‐service inspection data. The
sources of anomalies are explored and will try to be mitigated.
The case studies are carried out using three different platforms functioning in the
Norwegian Continental Shelf. Flowline system of each plant has been selected as it
has been given highest risk priority.
