DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil disaster prevention vessel for preventing marine pollution, and more particularly, to an oil disaster prevention vessel for quickly and easily recovering oil floating on the sea surface due to the grounding of an oil carrier. The present invention relates to an oil disaster prevention vessel for marine pollution prevention, which prevents pollution and enables reuse of recovered oil.

[0002]

2. Description of the Related Art Recently, during the operation of a ship by marine transportation, the accidental landing or sinking of a ship has often caused oil leaked from the ship to pollute the ocean.
In particular, when an oil carrier carrying oil lands, a large amount of oil loaded on the oil carrier leaks into the ocean, causing severe pollution over a wide area, and the spilled oil is more than imagined. Cause damage.
Next, the leaked oil rides on the tide and floats in the ocean,
Destroying coastal fishing grounds in fish farms, killing fish and shellfish in aquaculture, and destroying the ecosystems of coastal fishing grounds.

[0003] When such an accident occurs during the holiday season, the leaked oil flows into the beach, causing the bathers to feel unpleasant or, in severe cases, closing the beach. Occurs. Moreover, marine pollution caused by oil is extremely expensive, and it takes a long time to recover the original state due to the natural self-cleaning ability.

[0004] Therefore, various methods for removing oil leaked into the ocean have been studied in order to promptly cope with a marine pollution accident caused by oil leakage and to protect the national property and the natural environment. That is, as one method, first, there is a method in which a chemical is administered to an area where oil has leaked to precipitate oil floating on the sea surface on the sea floor, but this method does not actually collect oil, It is only to prevent oil from floating on the surface of the sea. The oil chemically reacts with chemicals and precipitates on the seabed, thus continuously destroying ecosystems. Thus, developed countries rarely use such methods.

[0005] As another method, there is a method in which a nonwoven fabric is introduced into an area where oil has leaked and is adsorbed. Such a method is somewhat effective when the amount of leaked oil is small, but it is widely used. It is a primitive method that is ineffective if oil spills into an area. Further, if the nonwoven fabric on which the oil is adsorbed is discarded, there is a possibility that environmental pollution will be generated secondarily.

Another method is to manually pump oil floating in the ocean, which is a primitive method that can be performed only when the amount of leaked oil is small.

[0007]

However, such a conventional method of removing oil from marine pollution is ineffective when a large amount of oil leaks over a wide area, and even if the disaster prevention work on oil has been completed, it is difficult to remove the oil. There was an inconvenience that contamination occurred secondarily. Accordingly, an object of the present invention is to quickly and easily recover a large amount of spilled oil over a wide area, and to make it possible to reuse the recovered oil, thereby preventing the destruction of ecosystems. It is intended to provide an oil disaster prevention ship for prevention.
