摘要： PROBLEM TO BE SOLVED: To provide a sinking and placing method capable of reducing the size of a sunken tunnel forming wall to a required minimum. SOLUTION: A sunken tunnel forming wall 1 equipped with a cylindrical floating body 3 also functioning as a water-stop wall is floated by its own buoyancy and the buoyancy of the cylindrical floating body 3 and toward and moved to a sinking and placing site. Then, winches 32 are set on the sunken tunnel forming wall 1, the inside of the cylindrical floating body 3 is filled with water, the winches 32 are driven and the sunken tunnel forming wall 1 can be sunk into the bottom of water, and thus the sunken tunnel forming wall 1 can be made compact to the smallest limit size required.

摘要： PURPOSE: To save manpower by automatically detecting pitch and roll amount, when such ship's pitch and roll as hindering cargo handling work take place. CONSTITUTION: A ship-width direction reference plate 1 to be laid along the ship's center line, a ship-longitudinal direction reference plate 12 to be laid along the breadthwise direction and the vertical direction reference plate 13 to be laid along the horizontal direction, are respectively fitted to the shell plate 7 of a ship's hull. Also, a ship-width direction distance sensor 15, a ship- longitudinal direction distance sensor 16 and a vertical direction distance sensor 17 are respectively arranged on the wharf side 5. In addition, a distance judgement device is provided for receiving the value of a distance detected by the sensors 15 to 17 for comparison with an allowable distance.

摘要： PURPOSE:To prevent the suction of suspended matter and air entraining suction at the time of high speed turning. CONSTITUTION:Fences 4A, 4B are hung down along the bow-stern direction on both side parts of the opening parts of jet water suction ports 3 formed at the bottom parts of lateral hulls 1, 2. The height of the hull center side fence 4A between these lateral fences 4A, 4B is set higher than that of the hull outer side fence 4B. At the time of high speed navigation, the draft line between the hulls is lowered, and by turning, the draft line between the hulls on the outside of turning is further lowered, but air entraining suction from this draft line part on the outside of turning is prevented.

摘要： PURPOSE:To cope with small depth of water so as to provide great propulsion by effectively flowing water in and out even if a propulsion propeller is large in diameter. CONSTITUTION:A bow tunnel portion 3f, which slopes upwards from the bow to the stern at thetaf=10 deg.-15 deg. and leads to a propeller portion 3p above the water line WL, and stern tunnels 3R, 3L each of which downwardly slopes astern from the propeller portion 3p at thetae=4 deg.-6 deg. and comprises a stern tunnel portion 3e above the water level WL, are formed at the stern of the hull 1, and the propeller portion 3p is provided with pusher propellers 5R, 5L each of which has a portion that projects above the water line WL. A space portion S which is 5-6% to 0.06 of the diameter D of the propeller is formed between the upper end of each pusher propeller 5R, 5L and the stern tunnel inner surface of the propeller portion 3p, and a sponson portion which projects downwards from the water line WL by 10 to 15% of the diameter D of the propeller is hung down on the side of the propeller portion 3p.
