Description

Technical Field [0001] The present invention relates to a bio-fouling collecting robot for a ship hull,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bottom attachment recovery device, and more particularly, to a bottom attachment attachment recovery device capable of removing bio-fouling attached to the bottom and recovering the bio-fouling.

In the marine environment, the surface of the ship is in contact with many marine life forms for a long time. When the microorganisms are attached to the surface of the vessel by the contact, and a variety of biological species such as barnacles, mussels, polychaete worms, mosses, insects, Form biofilm on vessel surface.

Biofilm formation by attached marine organisms creates uneven structures on the ship's hull below the water surface and increases the roughness. As a result, it acts as a brake when the ship is sailing, slowing the speed of ship operation and increasing the fuel consumption of the ship up to 40% .

In the case of large container ships, this would result in an annual additional cost of millions of dollars. Increasing the weight and thus the structural load may make it difficult to steer and reduce the ship's operational performance and efficiency. In addition, it can damage the basic paint and expose it to corrosion, which can damage structures, equipment, and the like.

Therefore, it is a way to reduce the maintenance life and prolong the life of the ship by removing the attached organisms cleanly on the surface of the ship. However, since the marine life is so strong, it can not be removed easily after it has been settled.

Generally, the removal of the attachment debris on the surface of the ship is mechanically removed from the dry-dock that allows the ship to be repaired or cleaned, and is prevented by a chemical method. To do this, the ship must be delivered to the outage by gun election, which usually results in considerable economic losses due to the cost of the shut down as well as the cost of the required work.

In addition to the periodic removal of surface organisms from the dry dock, it is common for the mechanical removal method to remove the diver using a separate device, but it is an inefficient method where there is a risk and additional damage may occur.

Also, antifouling paints used to prevent the attachment of biologically chemically used antifouling paints using toxic marine growth inhibitors such as copper or tin salts, which are excellent in antifouling effect, are restricted in use worldwide and have low toxicity But the effect is too low to maintain long-term antifouling performance.

Therefore, it is necessary to remove mechanically periodically attached debris, but the debris generated as a result of the depletion will cause destruction of ecosystem and environmental pollution. Therefore, the debris generated after removal must be recovered and treated separately.

Until now, no debris has been recovered after removal of biological deposits in the water, but regulations on the recovery of debris that occur after the removal of biological deposits around the world will be enforced. Therefore, after debris removal work in water, It is desperately required to effectively recover the water.
