Pipeline Pigging Technology

Shortening of response time in finding information

The improvement in this area was very significant. In addition, there was
more confidence that information can be retrieved quickly when required.
Examples where this has been beneficial are:

ad hoc presentations to management and authorities;
preparing of annual reports;
answering of questionnaires from authorities such as 'Pipeline Aban-
donment Study Database'.

More cost-effective scope of ROV inspection

The system was used during the preparation of the 1987 ROV campaign.
It was found that the scope of work was prepared in a shorter time and that
it was necessary to survey fewer areas than in previous campaigns. This led
to a reduction of cost. However this may not be entirely attributable to using
the system.

Reduction in the number of reports

It was decided to keep the old reporting system in 1987, in parallel with
CIS-PIPELINE. In the light of the good performance of the system, it should be
possible to reduce the number of reports supplied by the contractors in 1988.

ADDITIONAL BENEFITS

On top of the foreseeable advantages, a number of additional benefits have
arisen from using CIS-PIPELINE over the past 18 months:

(a) Better reporting standards - Due to the establishment of a detailed
format for the magnetic tapes, inspection contractors have been
forced to report in a more standardized way. Consequently, the
quality of reporting has improved. It is also easier to cross reference
results from different inspections.

(b) Discovery of a number of inaccuracies in earlier data - The initial
database loading was accompanied by a complete re- validation of
