Offshore Fabrication & Welding in Darwin
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 Darwin and the Northern Territory. Darwin's East Arm wharf, fishing and defence fleets, and major LNG and civil projects demand certified welding and fast on-site response. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Darwin 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.

Fabrication
Components are fabricated in our Humpty Doo workshop by accredited welders to drawing and code.

Inspect & hand over
Welds are inspected and documented, the site is cleared and the completed work is signed off.
Welding & fabrication in Darwin, NT
Darwin is the Territory's industrial and maritime hub, built around East Arm Wharf, the new Darwin Ship Lift marine precinct and the working waterfront at Frances Bay. Add the INPEX and Santos gas supply bases and a permanent Defence presence at HMAS Coonawarra and RAAF Base Darwin, and the city runs on coded welding, structural steel and fast on-water repair.
From our Humpty Doo workshop we're on Darwin sites inside the hour, which makes us a practical call for both scheduled fabrication and breakdowns that can't wait for a barge or a southern supplier. Tropical heat, salt air and big tides are hard on steel up here — we build and repair to handle it.
