Description

Apparatus for removing adherent matters of ship and structures}

The present invention relates to an apparatus for removing attachments of ships and structures, and more particularly, to remove attachments of ships and structures that can easily remove various attachments attached to surfaces while moving in an adsorbed state on ships or marine and land structures. Relates to a device.

In general, a ship has a hull formed with a loading space for loading cargo therein, the hull is provided with various facilities for operation. Most of these vessels are operated with the lower part of the hull submerged or stayed anchored.

On the other hand, many sea creatures live in the seawater, and various marine life and moss are attached to the hull over time. One example of marine life is Barnacle.

Marine life attached to the surface of the hull increases the surface resistance of the ship, thereby reducing the operating speed of the ship, and increases the fuel consumption is a factor that increases the overall operating cost. In addition, marine life attached to the surface of the hull causes the paint of the hull to fall off, causing the hull corrosion.

Conventionally, the surface of the hull is coated with anti-fouling paints containing materials that marine organisms are reluctant to prevent marine organisms from adhering. However, at the point where seawater and air cross, the use of antifouling paint is limited, and as the seawater and air intersect, it is difficult to continuously maintain the effectiveness of the antifouling paint. Moreover, marine organisms attached at the point where seawater and air intersect further increase the surface resistivity of the hull as they form fine vortices in the seawater, and are clearly visible and not aesthetically pleasing.

As a result, the worker attaches a line to the hull, moves on the line, and performs cleaning to remove marine organisms attached to the outer wall of the hull, but the work is difficult and there is a risk of safety accident. In addition, since the bottom of the hull, that is, the bottom of the hull, should be cleaned by the divers, the work should be done in a lying position all day.
