But the case where alow face forms the air lubrication systems of air layer, the air layer is made of bubble, ocean Biological attachment is in the situation in the jet space for spraying air, and air lubrication systems are in structure by using existing water injection Mode, steam spray regime, brush rotation mode, vacuum suction mode etc. in water, the marine organisms for not only removing attachment are difficult Even if removing is also required to consume many activity durations, therefore there is a problem of not efficient.
In addition, in order to produce and supply air, compression is arranged in existing air lubrication systems on ship deck (deck) Machine room or setting air compressor, thus the phenomenon that generating the availability decline of deck upper space.
In addition, the case where air compression chamber or air compressor are arranged in hull, has a problem in that ship entirety Construction must be changed, therefore not only be not applied for the ship dried, but also cause expense to increase according to Ship Design change Add and drying time increases, thus whole productivity effect decline.
In addition, also there is the side of the setting air compressor room or air compressor in engine chamber (engine room) Case, but the engine chamber is located at the stern direction of hull, and air lubrication plant is located at the ship's head of hull, thus, For supplying the length of the air supply pipe of air, therefore problem is, pipeline setup fee and loss in tube head increase Adduction and pipe design complexity.
In particular, the case where air compressor is arranged in engine chamber, because the limited available space of engine chamber is to compressor Size be confined, cannot be efficiently with the various problems such as air lubrication plant so having.
