Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of shortening the time of constructing a terminal for liquefied natural gas (LNG) or liquefied petroleum gas (LPG). SOLUTION: The method for constructing an LNG or LPG terminal (3) including an external structure (7) and at least one storage tank (11) comprises a step of manufacturing the external structure, a step of simultaneously and independently manufacturing the storage tank, a step of allowing the external structure and the storage tank to be afloat after or when the manufacture of the external structure and the storage tank is completed, a step of allowing the storage tank to be afloat in the external structure, and a step of fixing the storage tank to the inside of the external structure.

Abstract:
PROBLEM TO BE SOLVED: To provide a floating terminal usable even when the state of a sea is worse. SOLUTION: This floating terminal 1 for loading/unloading a ship 9 such as a methane tanker is substantially formed of a floating caisson 3, and comprises a ship mooring means such as hawsers 11a to 11c and underwater skirts such as underwater horizontal skirts 15a and 15b. These underwater skirts damp the vibration of the terminal to reduce a relative movement between the terminal and the ship. The underwater skirts can be formed vertically or diagonally. In addition, a swell damping chamber can also be formed in the terminal. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PURPOSE: To protect a port or the like by mounting a caisson provided with an opening passing a swell, a pool part absorbing the swell and a plurality of parallel vertical skirt parts damping the swell. CONSTITUTION: When a swell F comes toward the side part 4 of a caisson 12 supported on a lattice metal structural body 22 , water of the swell enters the pool part 3 of a half-immersed state from a plurality of openings 5 provided on the side part 4. The energy of the water of the swell is absorbed in the pool part 3 to be damped, and damped in a partition chamber 9. The swell is damped by vertical skirt parts 11, 12.
Abstract:
PURPOSE: To make it unnecessary to use a lift device such as crane or the like and make execution safe and easy by reducing the risk of damaging members to be installed by towing a caisson partially submerged under water in a vicinity of the surface of the sea to an installation site and fixing the caisson on a predetermined support fixed on the sea bed. CONSTITUTION: Two sets of vertical partition walls 51 , 52 , 53 and 61 , 62 , 63 directed in orthogonal directions to each other from a slab 4 are provided, and communication between damping chambers 9 is established by providing openings 8 in the partition walls 61 to 64 . A vertical sleeve 7 is provided to constitute a caisson 1 made of steel reinforced concrete. A plurality of the caissons 1 are towed to an installation site in a floating state and installed on a support constituted by piles 2 for foundation driven into the sea bed 3. A protection device against swell is laid by housing ends of the piles 2 in the sleeve 7 and connecting the caissons 1 at end parts thereof. By such a method, installation can be executed easily without using a lift device such as crane or the like.
Abstract:
PURPOSE: To perform the modifying work of a protective barrier without stopping the function of a structure body by forming the protective barrier by use of at least two cell-like ballastable floating structures assembled along the vertical side part of the structure. CONSTITUTION: This protective barrier is formed of two semi-cylindrical elements 3, 4. The positioning of the elements 3, 4 is performed by connecting a connecting sleeve 24 supported by the longitudinal ends 26, 26 of the elements 3, 4 to the upper parts of preliminarily driven connecting piles 22, 23. Thereafter, the elements 3, 4 are rotated around the connecting piles 22, 23 and located in a final position, and the elements 3, 4 in the floating state are ballasted and lowered to the sea bottom. The elements 3, 4 are mutually connected in the side parts through a connecting means.
Abstract:
PROBLEM TO BE SOLVED: To provide a breakwater which is low in the construction and installation cost. SOLUTION: A breakwater is partly submerged in the sea and constituted of at least one unit of caisson and this caisson contains an absorbing basin 5 having a wall 6 positioned so as to face large waves coming from the direction H of the sea side. Both basin 5 and wall 6 attenuate the energy of large waves and have a plurality or openings 71 , 72 discharging at least a part of water entering into the basin. These breakwaters are installed in respective caissons and provided with one or more enclosed chambers 101 ,-104 , giving a perpetual buoyancy to respective caissons, a mooring device for the sea side end of the breakwater, and a regulating device of the movement of the land side start point (land side end) of the breakwater.
Abstract:
The invention relates to the assembly of a tube (1) made from composite material and a tubular metal part (2) in order to produce pipes. The assembly process comprises: - inserting a portion of the metal part (2) into the composite material tube (1); and - radially deforming the metal part (2) to a plastic deformation range sufficient to cause elastic deformation of said composite material tube (1), in order to obtain a radial contact between the outer wall of the metal part (2) and the inner wall of the composite material tube (1).
Abstract:
Cette installation comprend une éolienne (1) et un support pour cette éolienne, ledit support étant constitué par une plate-forme (7) à lignes tendues (8 i ), ladite plate-forme (7) prenant la forme d'un flotteur ballastable et déballastable. Cette installation est remarquable en ce que ledit flotteur (7) comprend au moins un caisson (7a) à section horizontale sensiblement triangulaire, ledit caisson (7a) étant raccordé à des corps morts (9 i ) reposant sur un fond marin (5a), par au moins trois paires (8 i ) de tendons, chaque paire étant installée entre un des angles dudit caisson (7a) et un desdits corps morts (9 i ).
Abstract:
