摘要： Method and apparatus for preventing foreign objects, such as ice floes, from entering into the docking basin of barge supporting floater-type vessels, floating docks, basin docks, canal sluices or the like, include nozzle apparatus provided at the regions of respective sides of the inlet to the docking basin for directing first and second strong, relatively narrow surface currents to create a flow field in the region of the basin inlet which prevents the foreign objects from entering into the docking basin. One of the surface currents is directed outwardly with respect to the docking basin so as to define an angle in the range of about 15.degree. to 35.degree. with respect to the transverse plane which passes through the inlet sides. The other surface current is directed outwardly with respect to the docking basin in a direction substantially normal to the transverse plane passing through the inlet sides.
