New technology for vessel cleaning gives a unique opportunity to clean
progressively underwater parts of vessels from biological growth. It
can be used for preventive purposes during the exploitation of a
vessel as well as directly before docking a ship.
The advantage of our technology is that it allows cleaning underwater
parts of the vessels from shellfishes as well as from large
accumulation of seaweed, which is difficult to remove using other
cleaning methods. Special equipment for this technology can be
assembled both in a light diving version and also in the version of an
automated complex with the use of underwater remotely operated vehicle,
which is capable to work on the underwater parts of the vessels (it
can be programmed). The use of diving equipment makes it possible to
carry out the job even in the narrow places such as screw-rudder group,
Kingston valves, grating, protectors, etc. Application of the new
progressive and highly effective cavitation technology allows ship
owners and captains to reduce considerably the time of demurrage while
the cleaning of vessels from the biological growth is being conducted.
The proposed method is characterized by a high technological capacity.
The cleaning process makes it possible to preserve the paint integrity
and to keep toxic substances from getting into the water. Recommend
constant use of the proposed technology for the vessels with ordinary
cheap paints without toxic additions.
All the above mentioned advantages plus the use of normal seawater of
low pressure in the cleaning process make the proposed technology
secure and ecologically clean.
THE EMPLOIMENT OF CAVITATION EQUIPMENT ALLOWS:
- to carry out cleaning works, including inspection of the underwater
parts of ship hulls, screw-rudder group and bottom equipment;
- to carry out the examination and cleaning of underwater steel
constructions with removal of paint and corrosion hi the ports and
- to conduct the cutting of underwater concrete constructions.
High productivity, economic efficiency, ecological compatibility,
ability to clean even in narrow places and corrugated surfaces makes
this method attractive advanced alternative to widespread brushing.
