The operations -based GIS implementation


3.3 Mapping / Records management
The GIS System provides an integrated framework for the continued maintenance and use of pipeline data, as described under data and mapping maintenance above. This framework will provide consistency, integrity and extensibility of data across multiple organizations and applications. This will help to reduce or eliminate various data management inefficiencies related to inaccurate, inadequate, outdated, unsecured, or lost maps, documents and data in multiple locations.
  • The GIS System greatly improves accessibility to a broad range of pipeline information by the ability to link documents to geographic features. This may include right-of-way documents, photographs or engineering drawings and maps, including CADD drawings. One example implemented is Emergency Response documents (in Microsoft Word format) which contain such information as how to access designated boom sites, phone numbers for local officials, etc. These documents are linked to icons displayed at the Emergency Response sites and accessed by simply double-clicking on the icon.
  • Engineering, Right-of-Way and Safety, and Operations all have needs for copies of the USGS quad maps across the entire LPL system. This represents an estimated periodic cost of $18,000 that could be largely eliminated. We estimate $5,000 of these expenditures could be saved annually. The GIS System provides this mapping and can be kept in a more current and consistent state. The routing of the pipelines is also be current, complete and accurate. Currently the pipe centerlines are hand-drawn on these maps by personnel in these departments or as located by USGS.
  • The current time lapse between when facility repairs, change-outs, additions and new line crossings occur and when they are as-built onto production drawings and alignment sheets creates much undocumented inefficiency. This time lapse can range up to 5 years. When an engineer or a PLM crew makes use of an alignment sheet, they can easily make false assumptions regarding the actual state of the facilities.
  • The data maintenance software automatically dates facility maintenance records. This further enhances querying abilities when it is necessary to identify facilities, such as sleeves, which were installed within a specific time frame.
3.4 Reporting / Regulatory compliance
The GIS System will facilitate more complete and efficient report generation for either internal planning or regulatory compliance purposes than was previously possible. Some examples are encroachment permits, foreign crossing reports, permanent repair reports, and DOT incident and annual reports.
  • One recent event provides a clear example of the cost savings to be achieved. A survey of all stopple tees on the Lakehead system was required recently by the DOT as a result of a release. All of the lines in the system were analyzed and records were searched. The time required for this investigation was 150 hours for an Engineer and 350 hours for Engineering Services personnel over a span of 3 weeks. The time needed to complete the search on the GIS portion was 2 hours.

    One of the difficulties of this situation is that it was initially impossible to even estimate for Management or the DOT the number of stopple tees that were in question by the DOT. Until 2 weeks effort was expended, it was not known if there were 100 or 1000 fittings involved. Searching for this information involved going back to purchasing records, among all of the other information gathered. The number of fittings involved turned out to be 250.

    The cost for this investigation was approximately $20,000. With the GIS System in place, it is estimated the cost would be cut by at least 2/3 and preliminary estimates would be available within 1 day. The savings attributable to this investigation would be approximately $13,000 if the GIS System were operational for all of the Lakehead system.

    The resulting data from this type of investigation will be lost if it is not incorporated into the GIS System, as there is no process in place to store or maintain it. With the increasing reliance on contract workers, the data that is gathered by this type of investigation is no longer valid within a short period of time after the project is completed. With contract staff performing the data gathering each time it’s needed, there is little hope of retaining knowledge regarding the data from a previous investigation that was done perhaps 3-5 years previously. Data investigations of this type are done at a rate of 3 each year.

  • Another example is a second investigation this year requiring information on sleeves. This involved a total effort of approximately 520 hours over a 4-week period, amounting to $18,000 in cost for internal labor. The information for Lines 6A and Line 14 was produced by the GIS System within 3 hours. The GIS System, if implemented for the entire Lakehead system, would easily have saved $16,000 in internal labor costs. Assuming 3 investigations per year at estimated savings of $15,000 each, the total annual savings would be $45,000.
  • The National Pipeline Mapping System is based on the submission of location information by pipeline operators. The information for the Lakehead system was produced last year by a drafter at a cost of approximately $33,000 for 960 hours of work over a period of 8 months. This information could be provided more accurately by the GIS system at a cost under $3,000 and within 2 weeks. The lost opportunity cost for this work was $30,000
  • In response to various proposed rulemakings and information requests, Lakehead Pipe Line provides information to the API and regulators to assist in determining the impact and risk of proposed regulations. The use of the GIS System would greatly assist in and reduce the effort expended in responding to these requests. This is done on a yearly basis and generally requires several weeks of work. It is estimated the GIS System would save half of the cost of these investigations.
3.5 Environment / Safety
  • Environmental Sensitivity Mapping for Lakehead was completed in 1990 at a cost of $60,000, including third-party consulting, Lakehead manpower and color duplication. Many copies of these maps have been made and distributed for emergency planning and response. There are many cut-and-paste versions of the maps prepared to develop more detailed site specific response plans. Two sets of these maps have been submitted to DOT / RSPA as required by regulations. They have also been submitted upon request to state emergency and environmental agencies. These maps have not been updated with any pipeline or environmental delineation changes that have occurred since 1990. The choice of information to be detailed on the GIS-generated maps could also be easily adapted to each requestor’s needs. The GIS provides a much more efficient method for updating, printing and distributing this information.
  • The existing maps did not contain the National Wetlands Inventory (NWI) mapping of wetlands on them. This information is included in the GIS System for next to no cost via the Internet.
  • In emergency response situations, Lakehead personnel currently use a number of different maps to aid in planning their response, such as for access to the site, pipeline information, likely drainage direction, proximity of waterways, investigation by the Office of Pipeline Safety (OPS), etc. In planning and directing the emergency response, field personnel may have different maps or do not have ready access to all maps or information needed. The GIS System provides the same, consistent mapping and information to everyone involved in the same format including the ability to make custom maps that can be read from any location with GIS immediately.
3.6 Alignment / Route sheet generation and maintenance
Alignment sheets are generated from the GIS System by alignment sheet generation software. This process eliminates the need for manual updating or complete re-drafting of the sheets since they are now just a report from the GIS System.

Lakehead currently spends an average of 6 months of labor each year updating a portion of the alignment sheets. The sheets are updated on average every 3-5 years for facility data, and generally not updated for land base information. It is estimated to take 1 FTE (Full Time Equivalent) to keep all facility information maintained continually for all lines.

With the GIS in place, all facility information for the entire system would be maintained continually up-to-date with approximately 2/3 of an FTE. Much of the maintenance of the data is automated or “assisted” by use of the GIS maintenance software and the integration of the PLM Reporting System with the GIS. The difference in cost for data maintenance for pipeline facilities is 1/3 of an FTE, or $24,000 annually.

Included in the implementation costs for the GIS System is the updating of the alignment sheet data for all lines, producing completely up-to-date alignment sheets for each line as it is brought into the system. This is a direct saving which would be realized as the rest of the Lakehead system is brought into the GIS System.

The one-time effort of bringing all alignment sheets up to date as of the beginning of the GIS project is estimated at 18 months for 1 FTE. This represents $109,000 in savings when GIS is fully implemented.
