Marine Contracting

Our maritime construction capability

Our extensive experience spans the building and remedial maintenance of wharves, jetties, pipelines, pontoons, barges, beacons, walkways, and any other steel, timber, concrete and aluminium products in marine environments.

We have completed two significant vessel dismantling and disposal projects – the ex HMAS Hobart and ex-HMAS Adelaide – along with major cliff stabilisation, and level and construction support works.

  • Project planning and advisory services
  • Installation or removal of piles
  • Removal or construction of bridges, boardwalks, piers and jetties
  • Pipeline trenching and construction
  • Port and marine infrastructure works
  • Vessel decommissioning and dismantle
  • Demolition of existing marine infrastructure
  • Cliff stabilisation
  • Levee support and construction

Marine contracting risk management

We understand the risks associated with marine contracting and are proactive in working to minimise this. McMahon Services has a robust and thorough risk management system that lends itself to more and more complex marine projects. 

Our marine contractors are exposed to a number of risks on a regular basis that we work to mitigate, including:

  • Wave action
  • Tide action
  • Strong currents or swell from passing traffic

While working in the ocean is like any other day at McMahon Services, we do take precautions to safeguard against the weather and environment. Our scaffolding team create innovative solutions to the problems working in and around the ocean that mean our staff are safe and your marine contracting services can progress efficiently.
