Humpty Doo Welding and Fabrication
Marine & Offshore

Marine Construction

High-strength welding, structural repairs and custom fabrication for vessels, pontoons, offshore structures and marine infrastructure.

Overview

Marine work built for the Top End's harshest conditions

From wharf upgrades to pontoon fabrication and on-water repairs, our marine construction crew delivers high-strength steel, aluminium and stainless work that stands up to saltwater, tide and constant load. We mobilise to slipways, jetties and offshore structures with fully-equipped rigs.

Every job is project-managed end to end — survey, fabrication, install and sign-off — so tier-one contractors get one accountable team from quote to handover. No job too big or too small.
