Stripping marine growth
Most work is carried out by divers using a hand held jetting gun fitted with a retro-jet which balances the diver in the water. For this reason it is common to use higher rated pumps for this application as only 50% of the pump power is utilised for cleaning/cutting.
Pumps for this application use seawater so the pumps are constructed with stainless steel pumpheads (431,316 or Duplex). For deep water work a jetting device is attached to an ROV, Hughes Pumps have even manufactured ROV mounted, marinised pumps for use 2000m subsea where it is not practical to use high pressure hoses from the surface.

Benefits of Water Jetting
- Removes any marine growth without damage to the substrate
- Can use seawater as the cleaning medium
- No pollution
- Fastest of any cleaning methods
- Versatile – can be used for a variety of cleaning/cutting tasks
- With a simple abrasive cutting attachment the same pump can be used to cut through thick steel structures subsea for decommissioning work
- Often the only suitable method for cleaning
- Pressure can be increased to 2000-2500bar for paint removal
- The pump is versatile & can be used for other cleaning & cutting applications
- Can be used manually or on ROV’s
