METHOD FOR INSTALLATION OF PROPELLER

摘要

PURPOSE: A propeller installation method for a ship is provided to reduce whole procedures by installing a retractable thruster on the sea. CONSTITUTION: A propeller installation method for a ship is as follows: a step for loading a propeller in a space part of a floating housing(S100); a step for submerging the floating housing underwater by charging water into the floating housing(S200); a step for matching the installed part of the propeller and the position of the floating housing(S300); a step for discharging the water from the floating housing so that the floating housing can contact to the installed part of the propeller(S400); a step for coupling the installed part of the propeller and the floating housing(S500); and a step for coupling the propeller to a hull. [Reference numerals] (AA) Coupling the propeller installation part at the underside of the hull with the floating housing; (BB) Coupling the propeller to the hull; (S100) Loading a propeller in a space part of a floating housing; (S200) Submerging the floating housing under the water by filling the floating housing with water; (S300) Matching a propeller installation part at the underside of a hull to the position of the floating housing; (S400) Draining water from the floating housing to allow the floating housing located below the underside of the hull to float up and contact the propeller installation part at the underside of the hull;
