Marine Fabrication & Repair in Darwin
Expert welding, fabrication and structural repair for marine vessels, pontoons and offshore structures.
Marine repair that gets vessels back in the water
Humpty Doo Welding and Fabrication delivers marine fabrication & repair 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.
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.

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.
