Aviation Fuel Systems Leak Detection and Repair

Anderson AFB, Guam

A leak found in the jet fuel gas pipeline system at Anderson AFB, Guam threatened the Air Force’s ability to maintain tight flight schedules, base safety and a healthy environment.

Upon performing routine testing of the fuel lines at Anderson AFB under Conti’s Air Force leak detection and annual tightness testing contract, the team discovered a critical leak. Conti mobilized to this pacific island site to lock-out, tag-out and replace a leaking 8” fuel line with a new double-block-and-bleed system. Quality control activities included holiday tests, nitrogen pressure tests, welding and welding x-rays before the new piping system was approved and the crew performed continuous air quality monitoring.

The team performed this work alongside an active B-2 Bomber plane runway at odd times in coordination with the take-off and landing schedule. The team was often required to wrap up its current segment of work to accommodate for an incoming plane with only a few hours’ notice on any given day. The crew was escorted to its airside work station each day in accordance with the base’s strict security procedures. Conti pre-planned and effectively managed logistics and procurement of materials from the mainland to the project site and succeeded in completing this critical project on time for the Air Force.

Conti collaborated with active air field operations and the Department of Homeland Security to test and replace leaking pipelines on this critical Air Force base.
