Mine Maintenance in Nhulunbuy
Structural repairs, component upgrades and hardfacing for excavators, loaders, crushers and heavy mining equipment.
Keeping heavy mining gear in the cut
Humpty Doo Welding and Fabrication delivers mine maintenance across Nhulunbuy and the Northern Territory. Nhulunbuy's bauxite mine, port and barge operations on the Gove Peninsula need accredited welding and structural fabrication on remote schedules. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Nhulunbuy that we are known for Territory-wide.
Breakdowns don't keep business hours. Our mine maintenance crews deliver structural repairs, hardfacing and component upgrades for excavators, loaders, crushers, conveyors and haul fleets — on site, around the clock, wherever the work is.
We scale to planned shutdowns and emergency callouts alike, with accredited welders, mobile rigs and a fully-equipped workshop behind them. One accountable team from first cut to sign-off.

Welding & fabrication in Nhulunbuy, NT
Nhulunbuy, on the Gove Peninsula in East Arnhem Land, is built around a long-running bauxite operation, its port and the barge logistics that supply a remote community. Marine, structural and plant work here all run to remote schedules with limited local backup.
We mobilise accredited welders and fabrication crews to Gove for shutdowns, structural repair and marine work, with the documentation and traceability the resource sector expects. Getting it right the first time matters when re-mobilising is measured in days, not hours.
