The TGP Reporter, Version 3, is a custom pipeline data collection system
designed to collect as-built pipeline data. There were earlier versions that operated
within the DOS environment. We have since updated the software to work with
the Windows environment.
By capturing slope station and coordinate location information electronically,
Tennessee Gas Pipeline, a business unit of El Paso Energy, is able to substantially
reduce the time required to handle and process “as constructed” data.
Additionally, the data is in a format that easily migrates into our facility
management system.
The strength of the TGP Reporter lies in its integration with existing pipeline
survey techniques and with cutting edge GPS location technology. The system
allows field survey personnel to assign slope stations to features as the pipeline is
assembled outside of and next to the ditch. This technique keeps the surveyor out
of the trench and allows for rapid collection of data with a steel tape. Once the
pipe is lowered into the ditch and back-filled, an on-the-ground final survey, using
GPS, is used to collect the coordinate location of all horizontal and vertical bends.
A subsequent calculation process assigns coordinates for all the remaining slope
stations captured during the steel tape survey.
This latest version of the TGP Reporter has been redesigned to closely integrate
with El Paso’s facility management system. The data collection process has
implemented many of the corporate data model’s business rules, insuring that the
field data being received is cleaner than ever before. To streamline the loading of
data to the corporate database, the TGP Reporter’s internal data model has been
updated to mimic the corporate database. This function allows a one-to-one
relationship to exist between that data that is collected in the field and those
features in the corporate database.
The calculation package that supports the data collection process has also been
enhanced with the 3.0 version. TGP Reporter now supports the following
pipeline calculations:
Drag corrections
Lap and Gap
Bump
Reverse
Multiple 0+00 sections
X,Y,Z determination from slope stations
These calculations allow the users to address any construction scenario, and allow
the use of flexible field data collection techniques. If it is a construction practice
or possibility, then TGP Reporter has been designed to take that into account.
The TGP Reporter includes reporting functions that allow users to produce
material by station and material total reports. Also included are usercustomizable
reports that allow for ad hoc queries and reporting.
To efficiently move the data from the field to the office, TGP Reporter is fully
integrated with El Paso’s middle ware facility data distribution and delivery
system. Once the data is captured in the field, it is automatically sent to the
corporate offices where it is reviewed and loaded into the facility management
system. By maintaining the close relationship between the TGP Reporter data
model and the corporate database, loading of data to the target system is relatively
easy. This allows El Paso to post data to the corporate database soon after the
pipeline is placed into service, thus making the records available to the pipeline
maintenance personnel quicker than ever before. Once posted, these new records
are also ready to be passed back to TGP Reporter for immediate use
