摘要： PROBLEM TO BE SOLVED: To provide a method for efficiently recovering oil by generating a strong water flow by the use of a propeller of an ice breaker or an ice-resistant ship so as to separate ice and the oil from each other.
SOLUTION: The ice breaker 1 forms an open channel 5 around an ice board 4a on outflow oil 3; the ice board 4a is surrounded by an ice boom 7; subsequently, the ice boom 7 and both terminal ends of an oil fence 6 are tied to each other; one-side ends of ice boom fixing ropes 10 are connected to at least two locations on the side of a location where the ice boom 7 is tied, respectively; the other-side ends are fixed to a stern of the ice breaker 1; the ice breaker 1 advances while forming the open channel 11 in the central direction of the ice board 4a; after that, a strong water flow is generated by means of the propeller of the ice breaker 1; and the water flow makes the outflow oil 3 separated from the ice board 4a so as to make the outflow oil 3 removed by floating up to the open channel 5 between the ice boom 7 and the oil fence 6.

摘要： PROBLEM TO BE SOLVED: To provide an ice braking ship propeller blade, an ice breaking ship propeller, and a ship equipped therewith capable of suppressing the occurrence of sonant while keeping blade structure strength and independent efficiency of a propeller without extremely thinning the thickness of a trailing edge of the propeller.
SOLUTION: The ice breaking ship propeller blade 10 comprises a back surface 1 having a circular arc shaped propeller blade cross section, a flat shaped front surface 6 opposed to the back surface 1, a circular arc part 4 having a circular arc shaped cross section contacting with the front surface 6 in the trailing edge part, and a straight line part 3 having a straight line shaped cross section continuously contacting with the circular arc shape part 4 at a knuckle point 2 of the back surface 1. In this case, the diameter (d) of the circular arc shaped part 4 is 50-75% of the diameter (D) of an original circular arc shaped part formed at the trailing edge part in the original ice breaking ship propeller blade having the back surface 1 and the front surface 6. The distance (a) between the knuckle point 2 (same as the position where the straight line part 3 is continued to the back surface 1) and the blade rear end 5 is within 5-10% of the chord length (L) of the blade.

SOLUTION: The ice breaker 1 forms an open channel 5 around an ice board 4a on outflow oil 3, and goes round to make the ice board 4a fixed by being surrounded by an ice boom 7. The strong water flow which is generated by means of the propeller of the ice breaker 1 makes the outflow oil 3 separated from the ice board 4a, and makes the outflow oil 3 float up on the open channel 5 between the ice boom 7 and the oil fence 6 so that the outflow oil 3 can be recovered.
