What is it and why did we develop it? The Conoco Pipe Line Asset Integrity Database
(CPL-AID) is a Microsoft Access database This database is not just a data handling tool for ILI
Logs CPL-AID is a historical database Previously, anomaly repairs were thought to be
final, i.e., “We’ll never dig here again!” The above statement is no longer true today Digging previously dug anomalies is to be expected
Why a database?
The database format is the most efficient method
Properly compiled, all significant pipeline maintenance, survey and repair data can be stored and correlated with this database
The initial database can be easiest constructed from a single digital ILI Log from the joint numbering summary
A database can provide quick and efficient pipeline integrity summaries
What does it do?
There is a multitude of different applications that can be applied to the database.ILI Logs - MFL Corrosion, Caliper, Ultrasonic, and
Inertial Logs can be correlated to allow evaluation of all data simultaneously
Combining data w/ C-Scans and C.P. data Past integrity repairs can be documented for
correlation with present and future ILI Logs for future repair programs
The database has tools to assist with an anomaly pick list
This database provides reports for the field use
Methodology
CPL-AID utilizes an old method by British Gas (PII) called Joint Numbering and we combine that with the offset distances to create Site ID’s or SID #’s. This method improves location accuracy, helping
to eliminate unnecessary digs This method keeps our DOT records current with
our pipeline maps. The joint by joint correlation effort is done in the
office prior to preparing a dig program, improving our log accuracy and historical correlation effort; thereby, improving our maintenance integrity program.
Added Benefits of CPL-AID
Standardization of Asset Integrity Data throughout the company. Utilization of same data input forms and verification
processes for consistency of data The Pipeline Leak and Inspection Report form is
used for the main data-input screen Centralization of integrity and repair data.
All personnel access the same data, input data the same way and use the same reports
Final Pick List Process
The pick list is pre-loaded prior to the Project Management Agreement (PMA) meetings.
Face to face PMA meeting is held Stacking of hands on selection criteria and repair
criteria before selection In addition, system unique repair criteria is
discussed and finalized. HCA’s, environmental, geological, landowners,
permitting and site sensitive areas are combined with the analytical data before finalizing the pick list
