Kewdale White Oil Line Project

Type of project: Oil Infrastructure

Client: NEWest Alliance
Location: Perth, Western Australia, Australia
Completed in: 2023

The Kewdale White Oil Line (KWOL) project entailed the relocation of a 13km pipeline from BP’s Kwinana refinery to the Kewdale Freight Terminal of Perth Airport, a requirement arising from the Thornlie Cockburn Link railway project.

Spiecapag was contracted for detailed design and construction of the new DN300 oil pipeline to be installed through Perth’s southern suburbs. A congested construction corridor (<5m wide) as well as proximity to local residences led to a concept design with over 90% of the pipeline to be installed using HDD bores.

Over 12 km of the pipeline was constructed using the HDD method across eleven crossings, eight of which exceeded 1 km. Each crossing was complex in nature, affected by adjacent railway activities, magnetic interference, limited work area and challenging geology. This was one of the largest HDD projects completed in a single pipeline in Australia.
