  • Patent number: 4135841
    Abstract: A heave compensator is disclosed particularly adapted for use in compensating the flow through a riser pipe employed in offshore drilling apparatus for surges and ebbs produced in the flow therein by the rising and falling of the surface platform or vessel in relation to the ocean floor. A telescoping section substantially identical to that incorporated within the riser is carried by the floating platform or vessel at a location remote from the telescoping section of the riser. The compensating telescoping section is connected into the flow pipe on one end and closed at the opposite end. The two telescoping sections are disposed normal to the earth's surface whereby gravity tends to extend the compensating telescoping section. The two lower portions of the respective telescoping sections are interconnected by a flexible cable passing over a sheave carried by the platform or vessel.

  • Patent number: 4132498
    Abstract: An anchor removing device is constituted by providing a wedge shaped breaking means tapered in the drawing-out direction, which is temporarily secured to the tip portion of an anchor steel member and a tension steel member encompassed with sheath coupled to the wedge shaped breaking means. After this anchor removing device has been inserted into anchor hole which is bored in the ground, a hardenable filler material is injected into the anchor hole to form an anchor body. The hardenable filler material may produce voids or contains a foreign material of a low rigidity, which produces the effect similar to that of voids, such as air bubbles. The material may be foamable polystyrene and a cork of a given porosity. Typical example of the hardenable filler material is a foamed concrete milk. At the time of removing the anchor, the edge shaped breaking means is withdrawn by pulling the tension steel member with a jack or the like.

  • Patent number: 4130994
    Abstract: This invention relates to means to produce an artificial reef or floating breakwater wherein a series of buoyant disks are strung on a buoyant flexible line in spaced relation to each other with the lower end of the line being tethered to its own anchor. These tethered disks are placed preferably in about 6 to 18 feet water depth from the shoreline. A series of these disk-anchors are strung along in or out of lines paralleling the shoreline and in various depths of water to provide effective grid means for eliminating or at least substantially reducing the erosion effect along shorelines resulting from wave action.The placement of the disk-rope anchor units is preferably in the water paralleling the shoreline and each unit is spaced apart from the other. However, the spacing is not critical but to accomplish the results sought to be achieved, the spacing ought to be close enough to be effective and yet not tangle with each other.

  • Patent number: 4129992
    Abstract: Laying tool for laying of submarine cable in a sea-bottom trench. The tool comprises a drag unit and a pulling tube joined by a cardanic suspension and drawn by a vessel for use under variable sea and bottom conditions. The cable is laid out from the vessel through the pulling tube, a canal in the drag unit, and, finally, into a sea-bottom trench formed by a ploughing device on the drag unit. This unit is constructed so that the cable is forced down onto the bottom of the trench even if the unit is not operating in a proper position due to a rough sea-bottom. Moreover, the drag unit is constructed so that all material turned up from the sea-bottom is pushed aside from the trench and the ploughing device. The laying tool is also provided with floating tanks adjusted so that the drag unit without cable will float but with cable it will sink. The tanks may be filled with both water and air to facilitate submergence and refloating of the drag unit.

  • Patent number: 4129991
    Abstract: A method of producing a concrete lined tunnel, or other concrete lined underground excavation, in which first a rough tunnel is excavated of a cross-section which is greater than that of the tunnel to be lined with concrete, whereafter a lost form is connected by support members to the inner surface of the rough tunnel spaced at a distance therefrom which corresponds to the expected maximum settlement of the inner surface under the influence of the rock pressure acting thereon, and finally applying a concrete lining to the inner surface of the lost form, while the rigidity of the support members relative to the rock pressure is made smaller than that of the concrete lining so that the support members may yield during the settlement of the rough tunnel.

  • Patent number: 4127004
    Abstract: The invention relates to platforms of the off-shore type. It consists principally in arranging the base of the platform in the form of an elongated reservoir able to float and of a sufficient length to serve as a support for a column during transport to the anchoring point. For positioning the reservoir-base on the sea-bed, the reservoir is first of all tilted under the effect of ballasting until one of the ends of the reservoir touches the sea-bed. Then the column is released to assume its vertical position by way of floats connected thereto; and the operation is completed by ballasting to bring the reservoir-base to a horizontal position on the sea-bed.
