Sectors

Energy and geothermal

Generation, geothermal, refining and gas. The date the unit comes back is set before anyone walks on site, and everything we do is measured against it.

Deposit does not come off on a schedule

The plant is only available when it is off.

Scale, product build-up and bore deposit are harder than the plant they sit on and softer than the tooling that would take them off. Water removes what is on the surface at a pressure chosen for the deposit rather than the substrate, so the tube, the blade and the vessel wall come back to bare metal without being thinned.

  • Turbine and blade descaling inside the shut, working around the disassembly sequence rather than after it.
  • Tube bundles, condensers and heat exchangers cleaned in place or on the lay-down area.
  • Tanks and vessels stripped of product, with the recovery and the disposal path agreed before entry.
  • Hydro excavation around live services, cable and buried pipework where a mechanical dig is a permit refusal.

What we are usually asked to remove here

Shutdown crews travel. Auckland, Taupo, New Plymouth and the far south, on the dates the outage calendar gives us.

We've used Aquamax for 15 years on our annual shuts. I continue to be impressed with their project planning, health and safety management and the quality work delivered for us.
