Enbridge sponsored the construction of the Flanagan South Pipeline Project, a nearly 600-mile, 36-inch diameter interstate crude oil pipeline that originates in Illinois and terminates in Oklahoma. The line capacity is approximately 600,000 barrels per day.

The 600-mile pipeline was split into five sections (spreads). Two pipeline contractors constructed the line. One contractor began in Pontiac, Illinois at the start of the line; the other began at the midpoint, in Warrensburg, Missouri. The line terminated in Cushing, Oklahoma. The work was completed east to west. Westwood supported both contractors with pipeline surveying services on the entire route, which included preliminary and as-built survey data.

At the peak of the Flanagan South project, Westwood mobilized up to 60 field crews on the job. The fast pace of the project required high levels of rapid flexibility and response. Data management and timely turnaround of data is vital to the success of a project of this scale. Westwood’s team employed a proven process for ensuring that accurate data deliverables and the project schedule was met.

Safety and Quality

Working long hours and sometimes 7-day weeks, Westwood developed a culture of quality and safety practices on the job. Safety programs supported Westwood’s project-close record of having in excess of 500,000 man-hours of continuous operations with no lost time or recordable incidents or accidents. Westwood’s team applied quality management and lessons learned processes before, during, and after the project to ensure continual improvement. The lessons learned process included input from Enbridge and Westwood personnel and was submitted to senior management. The team received a very positive response.

Social Responsibility

The scale of the project demanded close collaboration with the client, and regular engagement with communities along the route. Project awareness and social acceptance are critical to keep major projects such as Flanagan South on track. Westwood implemented its Giving Back (Community Partnering) program to support the clients’ social license commitment on the project. Westwood’s Community Partnering effort was recognized by Enbridge as a model for future projects.
