APA Group Completes Gas Pipeline, Brisbane River Crossing
(UC) — APA Group said it has completed the installation of a gas pipeline in Australia that included a 300-foot (905-meter) crossing under the Brisbane River.
APA contracted Diona Civil Engineering Contractors, with additional support from Coe Drilling, for the pipeline installation, completed at a depth of 33 feet (10 meters) below the river, as part of the Murarrie Looping Project.
The horizontal directional drill (HDD) and pipe pull involved a 500-ton drill rig, two franna cranes and six excavators. It was completed over 24 hours using 70 workers.
During installation, 300 feet of DN 300 gas pipe was pulled under the Brisbane river with detailed planning in design and methodology required to ensure accuracy of the alignment installation.
The new 300 mm high-pressure steel pipeline is a duplication of the Murarrie Pipeline, which provides gas to more than 88,000 customers.
