Kurri Kurri Lateral Pipeline & Facilities Project

Type of project: Gas infrastructure

Client: APA Group
Location: Kurri Kurri, New South Wales, Australia
Completed in: 2025

The Kurri Kurri Project is a buried gas transmission pipeline and storage pipeline that will connect the proposed Hunter Power Project at Kurri Kurri, near Newcastle in New South Wales, to the existing Sydney to Newcastle pipeline. This is a complex suburban project that required seven HDDs, eight thrust bores, nine creek crossings and associated facilities works alongside conventional trenching techniques. As the main contractor, Spiecapag delivered three main components:

A 14-inch medium-pressure (up to 6.9MPa) Lateral Pipeline consisting of approximately 21km of DN350 carbon steel pipe and one Main Line Valve assembly connecting the Jemena Gas Network offtake facility to the compressor station.
A 42-inch high-pressure (up to 15.3MPa) Storage Pipeline consisting of approximately 24km of DN1050, carbon steel pipe located downstream of the Kurri Kurri Storage Station. The pipeline will have approximately 100TJ of gas storage capacity and will supply the Hunter Power Station.
A 14-inch high-pressure (up to 15.3 MPa) Interconnecting Pipeline consisting of approximately 1.3km of DN350, carbon steel pipe connecting the Kurri Kurri Storage Station to the Kurri Kurri Storage Pipeline.
