Marine Fabrication & Repair in Gladstone

Expert welding, fabrication and structural repair for marine vessels, pontoons and offshore structures.

Overview

Marine repair that gets vessels back in the water

Humpty Doo Welding and Fabrication delivers marine fabrication & repair across Gladstone and Queensland. Gladstone's LNG, alumina and port infrastructure calls for coded pipe welding and heavy structural fabrication to tight shutdown windows. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Gladstone that we are known for Territory-wide.

Steel and aluminium hull repairs, pontoon work and structural welding for commercial vessels, barges and marine infrastructure. We work afloat, on the slipway and in dry dock, with 24/7 breakdown response when you’re down.

Keel, skeg, rudder, deck and plate work, plus corrosion-resistant treatments built for saltwater service. Accredited welders and one accountable team from haul-out to handover.

In your region

Welding & fabrication in Gladstone, QLD

Gladstone is one of Australia's busiest industrial ports, ringed by the Curtis Island LNG trains, alumina refineries and aluminium smelting. Coded pipe, pressure systems and heavy structural steel are core to keeping this plant running.

We bring coded welders and fabrication crews in for shutdowns and tie-ins to tight windows, with full NDT coordination and sign-off. When a shutdown clock is running, documented welds delivered on schedule are everything.
