Steep terrain has recently been faced by the pipeline, with the steepest slope along the pipeline route, The Escarpment, located on the Callide Range near Biloela, being 131 m high with a 30 degree angle rise.
Crews added a 200 t anchor block to their conventional equipment for the challenge, with machinery tethered to the block to allow safe clearing of the easement and trenching works.
20, 12 m sections of 1 m diameter steel pipe were welded at the bottom of the hill, with the string winched up 24 m at a time on rollers installed in the trench as each joint was completed.
The process took less than three weeks.
