Hydrocarbon Transmission Pipelines Managed with GIS Dashboard



 



The Saudi Arabian Oil Company (Saudi Aramco) operates and maintains the extensive network of hydrocarbon transmission pipelines that carry oil, natu­ral gas, natural gas liquids (NGL), and even products such as diesel. The total length of these pipelines exceeds by 15 percent the 13,000 miles spanned by the Great Wall of China.

This huge network of buried pipelines connects refining facilities, domestic cus­tomers, and export terminals. Pipelines cross the entire Saudi Arabia territory from east to west and north to south, encom­passing an area of diverse terrain and harsh environmental conditions. An enormous number of assets of various types are part of this pipeline network.

Operating the network and its related assets poses many challenges, which often necessitate implementing normal and emergency modifications to maintain the safety, reliability, and integrity of the whole transmission pipeline network.

The status of changes to the network and its assets must be tracked to ensure they comply with requirements. The transmission pipeline network, its related assets, and all modifications to the network and assets are maintained as an as-built pipeline network layout that is monitored by a comprehensive GIS application. The data for that GIS application is managed by a dedicated unit within the Pipelines Department of Saudi Aramco called the Pipelines Data Management Unit (PDMU).

Because the pipelines and assets are distributed over a wide area, geographic zones or areas of responsibility were cre­ated for the three main subdepartments within the Pipelines Department and for all operating units that report to each de­partment. This ensures project completion and compliance for normal and emergency changes.

 

Project staff come from different disci­plines, such as operations, maintenance, or inspection. They submit change requests, update progress data, and confirm the 

completion and implementation status of changes in the corporate enterprise re­source planning (ERP) system.

PDMU staff are not a permanent part of this process. To obtain information and data related to any changes implemented on the transmission pipeline network, in­tensive email communication between PDMU and Pipelines Department staff was necessary. These messages provided Pipelines Department management with status updates.

Developing the Pipelines Management of Change Application

To address the challenges of monitoring the pipeline network, a GIS dashboard solution was developed. This solution, the Pipelines Management of Change (MOC), enhances the tracking and monitoring of changes to the network and establishes a complete data update workflow for cap­turing and maintaining current pipeline asset data.

MOC is a GIS dashboard with two main components. The first component displays tabular data and change locations on a map. Selectable analysis charts and tables enable managers and key stakeholders to browse various types of information about normal and emergency changes. Managers can track the progress of changes and their status versus planned changes that have been scheduled.

The dashboard displays status charts or tables on the map georeferenced to its area of responsibility. By browsing charts and tables, changes that have passed the scheduled implementation date can be identified. The distribution of both normal and emergency changes is easily discerned because their locations are georeferenced on the map. This allows staff members to more immediately arrive at conclusions and supports decision-making.



The other main component of the GIS dashboard is a data update workflow. GIS was employed to improve the overall process. Because the ERP system is used by different Pipelines Department staff members for submitting MOC change requests based on geographic areas, this component initially fetches any new normal or emergency changes that have been en­tered in the ERP system. These changes are entered daily.

PDMU staff, using the analyses imple­mented in MOC, can focus on submitted requests for changes—classified as either emergency or normal—that will modify transmission pipelines and related asset data. A location tag on the map is created to reference the MOC request in case it can’t be referenced using an existing GIS asset. This is important for locating new assets that have been added or existing assets that have been relocated.

Based on the status of changes or their completion, a data update workflow is triggered. This workflow is monitored by PDMU staff and the PDMU supervisor, who ensure that the data is updated in a timely fashion and passes quality assurance/ quality control (QA/QC) processes. The GIS technology employed in this workflow enables users to zoom to asset locations affected by the MOC request and perform QA/QC on updated data by either approv­ing it or rejecting it and redoing the data update action.

With the solution, staff can iden­tify assets that have been removed or reallocated or newly added assets. Innovative GIS editing tools, email notifi­cations, and QA/QC levels with appropri­ate levels of review and approval maintain up-to-date pipeline GIS data.

Through a dashboard, MOC employs GIS technology to enhance visualization and track the location of normal and emergen­cy changes submitted by staff members who have different areas of responsibility. The app is integrated with the corporate ERP change management system and email gateway. The solution consists of a data synchronization agent that periodi­cally updates the change request data in ArcGIS Enterprise by importing data from the corporate ERP system through a REST endpoint.

MOC was developed using ArcGIS API for JavaScript and other enterprise tech­nologies. It was designed with flexibility in mind. Different user roles have access to specific functionalities such as data up­dates. There is a designated user role that grants access only to PDMU staff. The su­pervisor role determines who can approve or reject data updates.



 



Benefits Realized

The MOC application provides requested functionality and addresses concerns raised by management and technical staff. The GIS dashboard provides manage­ment with selectable charts and tables, so the progress of normal and emergency changes can be immediately monitored, and compliance can be ensured. These changes are extracted from the ERP system so that MOC acts as a gateway for browsing information without logging in to the system.  MOC enables the classification of chang­es that involve data updates to the pipeline as-built network and tracks the comple­tion of changes, ensuring data is updated accordingly. PDMU staff can monitor and track all changes implemented on the pipeline by various operation and mainte­nance staff. The custom GIS-based work­flow greatly assists in keeping GIS data up-to-date. It also eliminates major work related to customizing the corporate ERP system, which directs all pipeline-related changes to PDMU for review. ERP system customization would have delayed the project considerably and imposed major delays in executing changes.
