Offshore Fabrication & Welding in Newcastle
Custom offshore module construction, structural supports and complex fabrication for marine and offshore projects.
Offshore-grade fabrication and welding
Humpty Doo Welding and Fabrication delivers offshore fabrication & welding across Newcastle and New South Wales. Newcastle's coal terminals, marine fleet and Hunter heavy industry rely on coded welding and structural repair across port and plant. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Newcastle that we are known for Territory-wide.
Modules, skids, structural supports and access structures — fabricated and coded to class for the offshore and marine sector. Accredited welders, survey-ready documentation and full traceability on every component.
We mobilise to vessels, barges and platforms, and project-manage from workshop fabrication through to install and sign-off. Complex work, one accountable team.

Welding & fabrication in Newcastle, NSW
Newcastle runs one of the world's largest coal export ports alongside the heavy industry of the Hunter, from the harbour coal terminals to manufacturing and marine work. Port plant, conveyors and marine assets here demand coded welding and structural repair around the clock.
We mobilise crews for shutdowns, structural fabrication and breakdown response across port and plant. Coal dust and salt air are both hard on steel — we weld and fabricate to stand up to the lot.
