摘要： PURPOSE: To reduce the vibration level of wall and roof surfaces to a vibration level near a floating floor by attaching oscillation preventing jigs against oscillation of hull at the corners of a ship body and also installing a lock wool board of high density to give heat insulating effect and radiation sound insulating and absorbing effects to the steel plate surface of the ship body. CONSTITUTION: A lock wool board 7 of high density is stamped on a steel plate 1 as a sound insulating material used also as heat insulating material so as to reduce radiation sound. Also an interior wall 3 and a roof 4 are assembled in box form and supported by a float floor 2 only to eliminate a direct vibration transmitting route from the steel plate 1 so as to reduce the vibration level of the wall and roof surfaces. Because the vibration transmitting route is long in a batch vibration-proof system, the vibration level can be reduced largely by adding a damping performance to the wall material, and approximately the same vibration-proof effect as the floating floor 2 can be obtained in medium and high frequency ranges. When the rigidity of mounting metals 5 at corners is set large to prevent them from being deformed by the oscillation of a ship, a sufficient vibration-proof and insulation effect can be obtained by elastically supporting them with vibration-proof rubbers 6.

摘要： PURPOSE:To simplify the construction process, by fitting stud pins on a deflection proof material made of light alloy and fitting lateral joints thereto while unrolling a rolled heat proof material from one side of a joist structure in which vertical joists are attached on lateral joists. CONSTITUTION:Lateral joists 5 provided with oval holes 12, female screw studs 14, and stud pins 15 are made. Next, the oval hole 12 of the lateral joist 5 is positioned at the stud pin 11 provided at the flange 3 of a deflection proof material 2 and the lateral joist is fixed with washers 16. And vertical joists 6 are fitted on these lateral joists 5 at every required interval with poprivets 17 or the like. Then a rolled-up heat proof material 4 is unrolled on the plane of joists 5, 6 from one end thereof while winding off it in sequence and fixed with spring washers 18, 18'. In this way, no skillful technique is necessary and the fitting work is simplified and the construction period is reduced and the cost is remarkably reduced.

摘要： PURPOSE:To simplify the construction work and reduce the construction term, by forcing a rolled-up heat-proofing material to make contact with a part of a deflection-proof material made of light alloy while winding off the heat- proofing material and forming a space surrounded by the alloy plate or the deflection-proof material and the heat-proofing material near the deflection-proof material. CONSTITUTION:A deflection-proof material 2 made of light alloy is welded on a light alloy plate 1. Fixing members 4 are fitted at appropriate positions. The female screw studs 6 of the fixing members 4 are welded so as to form required spaces 10, 11 between the alloy plate 1 and the deflection-proof material 2 by the heat-proof material 3. The heat-proof material 3 is unrolled in sequence while the rolled-up heat-proof material 3 is wounded off from the one end thereof and stud pins 7 are inserted and fixed with washers 8 to finish it to form a single layer structure. In this way, the fitting work itself is simplified and the weight of heat-proof material 3, the construction period, and the construction cost are all redeced.

摘要： PURPOSE:To suppress the occurrence of a defect due to a discontinuity section of welding heat by forming a ground face flattened to the connection range with a reinforcing material on the surface of a butt weld section of a bulkhead, and forming a linear fillet weld section at the corner section between the bulkhead including the ground face and the reinforcing material. CONSTITUTION:The surface of the butt weld joint of a bulkhead 1 is flattened by grinding to form a reinforcing structure D. The range of a ground face 21 to be flattened is set somewhat larger than the width added with the width of a reinforcing material 3 and the width of both the right and left fillet weld sections 22. The reinforcing material 3 is mounted on the surface of the bulkhead 1 astride the ground face 21, and the fillet weld sections 22 integrating them are formed at the corner section formed by the surface of the bulkhead 1 and the side face of the reinforcing material 3. The fillet weld sections 22 are linearly continued, the occurrence of a discontinuity section of welding heat at the intersection between the butt weld joint and the fillet weld sections 22 is resolved, and the occurrence of a defect is suppressed.

摘要： PURPOSE:To eliminate high stress which in a hull transverse bulkhead structure suitable for use in a tanker was conventionally generated at the tie-in portion of the lower end of a vertical warp-proof material extending along a hull center line and a bottom structural member, particularly owing to a difference in loaded state between tanks in front of and behind a hull transverse bulkhead. CONSTITUTION:In a hull transverse bulkhead 6, part of the lower end portion of a center-line vertical warp-proof material 8 extending along a hull center line 1 is removed and plural stages of horizontal warp-proof material 12 are used to warp-proof the removed part of the transverse bulkhead 6. Even if one of tanks in front of and behind the transverse bulkhead 6 is full and the other is empty, high stress which was conventionally generated at the tie-in portion of the lower end of the center-line vertical warp-proof material 8 and the upper end of a center-line large bracket 11 is completely eliminated.

摘要： PURPOSE:To suppress outflow of a liquid cargo through a broken hole to the outside of a ship to a minimum limit by forming a release port device in the bulkhead of a liquid cargo carrier ship. CONSTITUTION:A number of liquid cargo tanks 1 and empty tanks 2 positioned adjacently to the liquid cargo tank via a longitudinal bulkhead 3 of a liquid cargo carrier ship are formed in a manner that the liquid cargo tank is partitioned from the empty tank through a transverse bulkhead. A release port device 6 like a valve usually kept in a liquidtight state and opened in the occurrence of emergency is formed in the intermediate part of each bulkhead 3. In the occurrence of emergency in which a ship hull is damaged due to running aground and a broken hole 7 is formed in a ship bottom, the release port 6 of each bulkhead 3 of the liquid cargo tank 1 corresponding to the broken hole 7 is opened, crude oil is moved to the empty tank 2 through the release port device 6, and outflow of crude oil is stopped in a state that internal and external pressures are balanced with each other at the broken hole 7. Thus, outflow of crude oil through the broken hole 7 is suppressed to a minimum limit.
