Application With Water Blasting Machine for Industry Washing

Ultra high Pressure (UHP) water jet blasting system uses pressure water from 1000bar to 2800bar used to clean the drain. And sewer and tube insider cleaning with 3D cleaning head.

It also can be used for paint for oil tank cleaning. And protective coating removal for ship hull , road marking or zebra crossing removal. This method is perfect for internal and external surfaces. Because the spray gun operator is able to access those “hard to reach” areas .

Besides, due to its strong water spray, the user can keep a safe distance from the surface being cleaned.

One of the major differences between high pressure water jet blasting machine. And other cleaning abrasives is the ability to contain, capture, filter and reuse the water. This eliminates waste water and contaminants after the cleaning.

Underwater robot ship bottom Cleaning

The purpose of underwater ship wall cleaning is to remove biological roughness or fouling. A build up of marine fouling can lead to increased drag. Resulting in a detrimental impact on a vessel’s hydro dynamic performance. Hence the relationship between speed power performance and fuel consumption.

Fouling, particularly in the case of a prolific build-up of hard or shell fouling like barnacles or tubeworm. It can cause turbulence, cavitation and noise. frequently affecting the performance of sonars, speed logs and other hull mounted sensors.

Underwater cleaning is performed either by a diver with high pressure cleaning pump or by a remotely operated vehicle (ROV) controlled from land . Proper cleaning removes all traces of fouling and does not damage the coating or cause any increased surface roughness.

Applicability and assumptions with water blasting machine

Hull cleaning is applicable for all vessel types and ages. Depending on the degree and type of fouling to be removed a diver can typically clean 300 to 400 ㎡ per hour of flat surfaces (less on the bow and stern areas).

It also can combining with crawler robot for big sea ship and boat to remove the old paint in a quick speed . Watex crawler robot also have vacuum system which improving the cleaning efficiency.

The operation will be performed during normal ship stops (bunkering, anchorage). The fuel reductions depend on the extent to which the hull is fouled.

Reduction potential
Depending on the degree of marine fouling, vessel size, vessel segment. Operation profile and trading areas a reduction in the range of 1% to 5 % on main engine fuel consumption can be expected.
