Onaero Twin Pipelines

Greymouth Petroleum

November 2012 to February 2013

Onaero, North Taranaki

Length: 2.9km

Size: 100NB Twin Line

The pipeline route comprised of a section of rural road with multiple services, some flat undulating farmland, a challenging hill section, river flats and a very steep section that required the installation of trench breakers. The crossing of the Onaero River required a 160m under bore for both of the pipes. The under bore was on target and went without a hitch.

Trench breakers installed on the steep section of the pipeline route.
