摘要： PURPOSE:To reduce a wave force exerted on a front wall and to dissipate even a high wave by means of a low mooring force by forming the upper front of a floating body in a shape rounded in a longitudinal direction and mounting a slope plate, having a rearwardly descending grade, on the rear side of the floating body. CONSTITUTION:An air chamber 3 extending in a laterally long manner is formed to the front part of a floating body 1 having a floating chamber 2, and a sea water flow entrance opening part 5 is laterally formed in the lower front part of the air chamber 3. An upper front part 1a of the air chamber 3 is formed in a rounded shape forming a gentle streamlined type. Further, an air hole 6 is formed in a ceiling part, through compression of air in the air chamber 3 by means of sea water flowing through the sea water flow entrance opening 5, air is discharged upward through the air hole 6, and operation to absorb wave energy is carried out. The proper number of buoyant tanks 8 is mounted on the rear end part of the slope plate 4, and mooring is effected by means of mooring cables 9 tied to the front end part of the floating body 1 and the rear end part of the slope plate 4.

摘要： PURPOSE:To alleviate the force of tidal wave acting on a marine structure by a method in which a contracted portion is provided at the center of the column for the diving section of a semi-diving type marine structure and a large-diameter footing is provided at the lower end of the column. CONSTITUTION:In a semi-diving type marine structure to be used in the drilling of seabed oil or gas deposits, a platform 1 is supported by plural columns 2 having a contracted portion 5 on its water-submerged portion and also a footing with a larger radius than the upper diameter of the column 2 on its lower end. By this, the vertical rocking movement of the marine structure by tidal waves when the columns are submerged in water can be largely alleviated.

摘要： PURPOSE:To effectively reduce pitching of a hull by providing a horizontal plate extending in the longitudinal direction of the hull near and below the water line on both side portions of the hull, and erecting a vertical plate on the horizontal plate to form water storage space. CONSTITUTION:A horizontal plate 4 extending in the longitudinal direction 3 of a hull 1 is provided near and below the water line 2 on both side portions of the hull 1 and a vertical plate 5 is erected at that end portion of the horizontal plate 4 which is opposite to the hull 1. Water storage space 6 open at its upper side and at both its front and rear end portions is formed by the horizontal plate 4, the vertical plate 5 and the side of the hull. A slit-shaped water inlet 7 extending in the longitudinal direction 3 of the hull is formed between the end portion of the horizontal plate 4 opposite to the hull 1 and the lower end of the vertical plate 5. Pitching of the hull is reduced by a damping effect due to an increase in weight by water flowing into the water storage space 6, a damping effect due to the flowing in and out of water through the water inlet 7, and a damping effect due to a time lag between the flowing in and out of water and the pitching of the hull.

摘要： PURPOSE:To improve the safety and efficiency of operation by reducing the heaving of a hull in which the operation is carried out under the stopped condition on the ocean. CONSTITUTION:Antiheaving tanks 2 are provided on the bow and stern of a hull 1. A duct 6 provided on the sidewall of the antiheaving tank 2 is opened to the lower portion of a side shell plate 3 so that the sea water can freely come in and out of the tank 2. Also, the antiheaving tank 2 is provided on the upper portion with an opening 7 through which air comes in and out. When the hull 1 heaves, the phase of the pitch of the sea water in the tank 2 is adapted to deviate from that of the hull 1, so that large damping force is generated and thereby an opening area A0 of the duct 6 in the pitch of the hull 1 is adjusted by a slide type regulator 8.

摘要： PURPOSE:To drastically reduce the rolling of a floating structure in a coast region by changing the shape. CONSTITUTION:As for the part 11a below the water level of a floating structure 11, the sectional surface shape 13 is made nonsymmetrical between the upstream and downstream sides 13a and 13b in the wave advance direction with respect to the vertical half division line L of the water line width (b) (draft line), and at least the upstream side surface 11c in the wave advance direction is tilted to the wave downstream side, and the forced moment of the wave for the rolling is reduced to reduce the rolling drastically. The shape of the sectional surface is formed to a parallelogrammic form, and the effect can be confirmed in the water tank test for a model which is tilted by 15 deg. to the wave downstream side.

摘要： PURPOSE:To sharply reduce the force of shock waves acting on a water-surface structure by providing walllike protruding pieces extended downward to an oblique plate and disturbing the condition of the water surface below the oblique plate when the position at which the water surface intersects the oblique plate becomes lower due to a lowering wave front. CONSTITUTION:Walllike protruding pieces 16 extended downward are provided to the lower surface 8 of the oblique plate 7 of a wave dissipation jetty in the vicinity of the position 13 where the water surface intersects the lower surface 8 when the water is calm. When the position 13 goes down due to a lowering wave front, the pieces 16 disturb the water surface below the plate 7 so as to prevent the water surface from becoming nearly parallel to the plate 7. Even when the water level goes up below the plate 7 thereafter, the collision of the water surface with the lower surface of the plate 7 in a slope condition can be prevented and the force of the shock waves acting on the plate 7 can be reduced. Therefore, the force of shock waves to a water-surface structure can be reduced by about 40% or more.
