A computerized inspection system
System development
Following the previous decisions, a functional specification was prepared
by TOM and issued as part of the call for tender for the development and
implementation of CIS-PIPELINE.
Scicon Ltd was awarded the contract. The system was developed between
September, 1985, and August, 1986.
SCOPE OF THE SYSTEM
Requirements
The data held for each pipeline is in three main categories:
construction and environmental data;
inspection data covering acoustic, ROV and internal inspections;
maintenance data.
The requirements of the system are:
to support batch input of a large amount of data supplied by the
inspection contractors on magnetic tapes;
to support interactive input/update of information;
to support interactive enquiries/reports on the information held;
to support detailed analyses of data from both past and present
inspections;
to provide data for graphical output, either to the screen or a plotter,
for some of the reports and analyses.
Expectations
The following points were considered to be the major advantages likely to
result from the computerization, thus justifying the development cost.
(a) Improvement of the awareness of the pipeline condition: By allowing
the results from previous and current inspections to be easily accessed,
summarized and compared (from one campaign to another or from one
method to another) the computerization would improve TOM's knowledge
