Description

Floating marine structure

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water structure, and more particularly, to a floating water structure that is structurally lightweight and has improved durability against an external impact.

Generally, there is a so-called cage farm in which a fish or an oyster is cultivated in a compartment made of a net or a net in the water such as a dam. The cage culture is widely used in the aquaculture field because it has advantages such as being able to use the natural environment without installing an artificial water tank and easily moving it if necessary.

Since these caged fish farms are usually located deep into the sea or lake, a water structure floating in the sea or water is required for people to approach for work or to transport goods between the farm and the land. This is significant and frequent, so barges are used rather than small ships.

On the other hand, a barge, also called a barge, is a flat-bottomed ship made for inland waterways such as rivers and canals, and heavy cargoes in port. Since the barge usually does not carry the engine, it can not navigate by magnetic force, and it travels while being towed to the towboat or pressurized by the towboat. These barges are used to transport cargoes from freighters anchored offshore in the harbor to riverside factories or warehouses. Recently, they have been used as a means for collecting seafood such as cage ponds in coastal waters or oysters and seaweeds have.

On the other hand, the barge which is used for the loading of the cage farm or seafood collected from the sea is used by connecting the suspension of the foam material to the lower side of the wood or steel material, and the float material of the foam material is easily Styrofoam fragments that are damaged, broken and fall off cause serious marine pollution.

In addition, when the styrofoam suspensions are shrunk due to the weight of the stacking load during prolonged use, the lifting force is remarkably lowered, and when the styrofoam is repelled by attachment of aquatic plants or fishes or the like, There has been a problem that the lifting force is gradually lowered.
