Wiggins Island Coal Export Terminal – Jetty and Wharf

Bonacci Infrastructure delivered the construction engineering, methodology and temporary works for the 1.8 kilometre long jetty and 450 metre long wharf in the Gladstone Harbour, Queensland, Australia as part of the Wiggins Island Coal Export Terminal (WICET) project.

Key features of the design included:

• A self-launching jetty cantitraveller which was fitted with a 300 tonne overhead lattice boom crane and two internal gantry cranes. The steel framed structure possessed driving gates which could accommodate both the typical and anchor bent piles, and was able to cantilever 24 metres to facilitate the driving process;

• A wharf traveller which was fitted with a 300 tonne overhead lattice boom crane;
• Wharf dolphin piling frames and wharf strong-point piling towers;
• Miscellaneous access platforms and paint cages;
• On-shore temporary works for the jetty cantitraveller, including earthworks, concrete foundations and piles;
• Cyclone contingency and launch planning; and
• Miscellaneous lift studies.
