SMALL WORKING SHIP, AND METHOD FOR COLLECTING AND LAUNCHING SMALL WORKING SHIP

摘要

PROBLEM TO BE SOLVED: To provide a small working ship capable of collecting and launching from a large ship without using a lift such as a crane. SOLUTION: Sleds having bow sides tilting upward in curved shape are installed on both sides of the bottom of the small working ship in areas ranging from the bow side to a stern side. The sleds are formed in a truss structure having vertical columns, diagonal columns, and sled members formed of hollow pipes. The upper ends of the vertical columns and diagonal columns are fixedly welded to a hull, the depths of the sleds on the stern side are deeper than the lower end of a propelling machine, and a rope hooking device is fitted at least to a bow part.
