Description

Cleaning system for exterior wall of ship

The present invention relates to a system for cleaning an exterior wall of a vessel, and more particularly, through a simple and efficient structure, an exterior wall of a vessel capable of easily cleaning the exterior wall of a vessel moving along a movement path without the need for a separate cleaning operation It relates to a cleaning system.

The speed performance represented by the daily fuel consumption is the most important performance among the various performance of the ship, and it is the key to minimize the resistance during design.

Resistance can be broadly divided into frictional resistance and surplus resistance. Most of the frictional resistance occurs when the surface is in contact with water. To reduce frictional resistance, reduce the area in contact with water or reduce the roughness of the surface in contact with water It is important to maintain the surface.

For this reason, before final verification of the built ship's performance, the ship's outer wall is cleaned to make the surface in a clean state, and then the test run is carried out. However, there is a problem in that a lot of time and money is consumed in this process.

In addition, as time goes by in operating a ship, a fouling phenomenon in which marine organisms such as barnacles are attached to the bottom of the ship inevitably occurs, and this fouling phenomenon increases the surface roughness of the outer wall of the ship, resulting in It causes a problem of increasing the fuel consumption of the ship.

In particular, the adhesion of fish and shellfish such as barnacles is not completely removed even if cleaning equipment is used, and when the coating film is severely damaged, enormous cost and time are consumed in the process of re-docking and repainting. There is this.

Therefore, by periodically cleaning scales or plants before attachment of fish and shellfish such as barnacles, delaying or preventing the occurrence of the fouling phenomenon in advance is to maintain the initial fuel efficiency of the vessel and to maintain the maintenance that occurs later. It is a very important situation from the viewpoint of reducing the cost.
