Exmouth Boat Harbour is one of the Department of Transports busiest maritime facilities. Work on the Exmouth Boat Harbour upgrade was made possible by Royalties for Regions investment of $18.275 million.

The Exmouth Boat Harbour upgrade project consisted of a major upgrade to the service wharf, including construction of a heavy lift facility, cyclone moorings and associated land-side wharf infrastructure.

Ertech’s contract for Stage 2 works included:

Marine structures

  • Extension of the existing service wharf by 94m including construction of a 40m heavy lift zone for crane lifts
  • Reconfiguration of the existing cyclone mooring system to make way for the new wharf extension
  • Construction of four new trawler pens and demolition of the existing trawler pens to make way for the new wharf extension
  • Breakwater works
  • Raising of the existing southern breakwater to provide adequate protection to vessels in the new trawler pens during storm events.

Civil works

  • Construction of heavy duty hardstand pavement behind the new wharf extension
  • Reconstruction of the harbour access road
  • Sealing of the fuel farm access road
  • Installation of wharf and hardstand drainage
  • Services to the new wharf and trawler pens including power, lighting, potable water, fire water, communications


  • Ertech offered an alternative method for the piling installation which involved roto-piling (spinning) the pile in with a very small annulus remaining which was then grouted. This reduced the program by six weeks (10%).
