This project involved the installation of a pipeline from Hunter River to the Bayswater power station storage reservoir.
Work undertaken was; the excavation of a 5M trench for 4.5 km of parallel 1450mm diameter “Syntakote” RRJ steel pipeline, installation of pipe, all flow control and air valves and scour branches, installation of surge tanks, welding pipe and connecting to inlet manifolds.
Work also included all electrical and controls work and construction of a 2.5 km all-weather access road & drainage
Restoration work was completed prior to final handover of the completed project.
The difficult part of this project was the handling of the 13.5 meter pipes. The weight of the pipes was approximately 6 tonnes and the Eire site team had to devise a method of loading, transporting and unloading along the proposed route. Eire obtained a large excavator from within its company fleet that could excavate through the rocky terrain areas and was also able to handle the longer pipe with ease. Each section also had to be spark tested prior to loading and again prior to installation.
Through fruitful negotiation between Tenix, Macquarie Generation and Eire the use of Fly Ash was adopted as a bedding and backfill material for line. This was considered a win win arrangement for the environment as the ash is a by product from the coal powered Bayswater Power Station.
