Dry dock time reduced using high pressure water

Dry Dock Surface Preparation Time Reduced
An industrial services company has ordered three of our mobile MultiJet high pressure pump units. Check out our MultiJet range. A UK shipyard will use these machines for
marine paint removal from ships’ hulls. We recently supplied a Dockmate surface preparation machine which will work alongside the three MultiJets.
Our pumps and accessories are everything you need for dry dock cleaning.
Why high pressure water?
Using water eliminates the harmful and often damaging side effects produced by dry abrasive blasting such as airborne dust, chemical/thermal pollution and surface ingrained residual blasting materials. The energy of the high velocity water jets blasts into the pores in the metal surface flushing out solid foreign matter and non-water-soluble pollutants such as oil and grease and returns the substrate to its original profile ready for re-coating.
With high pressure water there is no requirement for sand or grit. The operators will prepare the surface remotely without the need for scaffolding or other access equipment.
Why Calder MultiJet?
For many years, we have manufactured MultiJet units for surface preparation applications. Recent upgrades to our tried and tested design includes EU Stage V Emissions-compliant engines giving the very latest in low emissions technology.
Among the many benefits of the Calder MultiJet are the electronic throttle control. This increases engine speed only when pressure is demanded thus saving fuel and water. Our water filter assembly protects the pump from contaminated water. The ‘fast clamp’ system makes filter changes easy, and the unit features a continuous water filter monitoring facility with on-screen alarm and shutdown.
Why Hammelmann Dockmate?
The Dockmate is a semi-automatic machine capable of removing up to 150 square metres of coating per hour. Featuring a telescopic jib and rotating blast head, these machines are a truly versatile tool. The blasting head seals directly onto the hull surface and connects to a vacuum unit via hose/pipework combination. Filtering and re-using the water is a significant benefit of using the Dockmate.
