InterCavi, Ltd provides services for cleaning marine vessels of various classes from biological formations.
Cleaning is carried out using various specialized tools based on the principle of a cavitation jet.
The cleaning procedure takes place directly in the water, due to which cleaning can be carried out both in the port area and in the open ocean.
The period of work depends on the complexity of the ship's structure, the area of the underwater part, the complexity of pollution, as well as weather conditions.
The company InterCavi, Ltd carries out a set of measures for cleaning ships by cavitation from such biological formations as various algae, sponges, mucus and, of course, balanus.
These formations can grow in tons to the bottoms of ships, making them heavier and slowing down the navigation speed, which leads to additional costs for cleaning the bottoms and annual losses of millions of countries that own a significant fleet.
According to research data, the loss of speed due to fouling is 8-15%, and the increase in fuel consumption is up to 20-35% over the interdock period. Under favorable conditions for marine organisms, their mass on the ship's hull can reach 200 tons in two months.
Fouling of bottom or transom sensors - echo sounders, lags that are constantly under water, sharply reduce the effectiveness of their action and, therefore, complicate the operation of ships.
Fouling only directly to the propeller due to a decrease in hydrodynamic characteristics increases direct fuel consumption by 5-8 percent. With intensive fouling, the propeller becomes hydrodynamically heavy, which leads to significant engine overload.
It is estimated that the US merchant marine suffers annually in excess of $ 100 million in fouling losses.
The cavitation cleaning method is carried out using a jet of water with air bubbles dissolved in it. Penetrating through the porous structure of contamination upon contact with the surface, the bubbles collapse, forming a microexplosion followed by a water hammer. As a result, the contaminating layer is separated in pieces from the hull of the ship.
With high cleaning efficiency, the cavitation jet does not damage either the hull or the protective coating of the vessel, unlike other cleaning methods such as high pressure jet cleaning, chemical cleaning or mechanical cleaning.
Possessing a wide range of special tools, our specialists are ready to clean any vessels with any complexity of pollution in the shortest possible time. Our technology makes it possible to carry out measures to clean up ships from pollution without using dry docks. We can clean both in port and in the open ocean.
