    摘要: A method of supporting a structure, such as a drilling structure used in offshore oil activities. The structure includes a caisson having at least one ballast cell and a plurality of skirts extending downwardly below the base of the caisson. The skirts define compartments which are open at their lower ends. The structure is floated to a location at sea and is then sunk. Ballast is then introduced into the ballast cell to cause the skirts to penetrate downwardly into deeper layers of sea bed soil. The skirts thus form closed compartments. Sea water trapped within the compartments is then removed and ballast is then removed from the ballast cell to reduce the vertical load on the sea bed to a load level such that the sea bed material does not fail. Movement of the structure is primarily restrained by adherence and friction between the sea bed and the skirts and by temporary pressure differentials within the closed compartments created by partial movement of the structure.

    摘要: An elongated, hollow tubular member is compartmented to enable it to be floated in a water covered area to a desired location. Each compartment is provided with valve means in the form of an inflatable arrangement, which upon deflation communicates water to the compartment for flooding thereof. At least one piling may be positioned longitudinally within the hollow tubular member and sealably engaged by the valve means so that when the valve means is opened, and the tubular member sunk and positioned on the bottom in the water covered area the piling may thereafter be driven into the water covered area to aid in positioning the tubular member.

    摘要: The invention relates to a submersible caisson adapted for use in the construction of sea or river works, of the kind comprising a bottom, at least one lateral wall and a dividing-up device for liquid ballast forming a cellular structure in section substantially parallel to said bottom. The said dividing-up device is a structure completely independent of the wall and the bottom of the caisson which can thus be calculated precisely in accordance with the applied stresses. Many alternative forms of construction are given and the applications referred to are fluid-storage reservoirs, dykes, breakwaters, quay walls, lock walls, dam elements, etc.

    摘要: A plant for the manufacture of floating concrete structures in open and substantially unsheltered bodies of water, comprising a concrete ring floating in the water with its axis normally substantially vertical and its upper end above the water surface. The wall structure of the concrete ring includes a plurality of circumferentially spaced, pressure-tight, preferably cylindrical cavities extending in the axial direction of the ring. At least some of these cavities are adapted to serve as ballast and trimming tanks which can be filled with water to a variable extent, whereby the buoyancy, the floatation height and the attitude of the concrete ring in the water can be controlled. The total volume of the cavities is such that the total displacement of the concrete ring exceeds substantially the total dead-weight of the ring. The water area enclosed by the concrete ring is efficiently protected against wave motions, currents and winds, wherefore the manufacture of floating concrete structures can take place in this water area substantially without any disturbances from weather forces. The upper ring-shaped end of the floating concrete ring supports all those apparatuses, equipments, devices and facilities that are necessary for the production, such as concrete mixing stations, cranes, elevators, conveyors, electric power plants, compressed air plants, pump stations, control stations for the control of the ballast and trimming tanks of the concrete ring, workshops, crew spaces etc. Some of the large cavities in the wall structure of the floating ring can also be used as store spaces for materials necessary for the production, such as cement, gravel, sand, reinforcement materials etc. The concrete ring is moored through a large number of mooring ropes to an anchor resting upon the bottom of the body of water. The anchor consists preferably of a concrete ring having a wall structure including a plurality of circumferentially spaced, sealed, pressure-tight cavities adapted to serve as ballast tanks which can be filled with water to a variable extent for determining the total weight of the anchor ring and thus the anchoring force thereof. Preferably, the total volume of the ballast tanks in the anchor ring is such that the displacement of the anchor ring in the water exceeds the deadweight of the anchor ring, whereby this can be brought to a floating position in the surface of the water in that the ballast tanks are emptied. In this way the anchor ring can be towed in a floating position to the intended site of use.
