The device further includes a locking and tensioning device that includes at least one actuator secured to the floating support structure and is mounted to pivot on the second tubular connection element about a hinge axis and against the effect of a return spring surrounding the pin so as to enable the first tubular connection element to snap-fasten onto the second tubular connection element.
Abstract: A method of cutting a well casing located beneath a subsea wellhead wherein a cutting assembly is made and lowered into an operative position. A mounting device is secured to the wellhead and the cutter is radially expanded into engagement with the casing. The motor is operated so as to rotate the tubing string and thereby rotate the cutter to cut the casing. A cutting assembly is used to cut a well casing. The cutting assembly has a motor mounting device, a motor, an output shaft, a radially expandable cutter and a tubing string. The tubing string connects the cutter to the output shaft of the motor and clamp members secure the mounting device to the wellhead so that the rotary reaction forces from the mounting device are transmitted to the wellhead. Axial reaction forces are also transmitted from the mounting device to a radially extending surface of the wellhead.

The left and right side parts include stepped surfaces and a plurality of round shaped projection parts are closely disposed on the front wall. The block further includes two connecting walls having male protrusions and female recesses formed on upper and lower surfaces thereof.
Abstract: A modular erosion and sediment control barrier. The linear modular erosion and sediment control barrier is constructed of fiber logs joined end-to-end. Each fiber log is made of a quantity of loose fibers retained in a tubular casing by a plug. The tubular casing includes an extended section which is peeled back and folds over the end of the coupler fiber log during storage and transportation. When deployed, the extended section is unfolded to receive the end of an adjacent fiber log. The two fiber logs are secured together by a cord and hooks.

Abstract: A connector is provided for removably attaching a space frame to the hull of a floating offshore platform. The connector comprises a socket attached to the hull of the platform. The socket has an open bore therein. A stabbing member is attached to the space frame. The stabbing member has a lower end insertable into the socket. An expandable locking ring is carried by the lower end of the stabbing member. The locking ring comprises a plurality of ring segments for removably seating within the socket bore. A backup ring is slidable along the stabbing member. The backup ring removably mates to the locking ring.
Abstract: A loading arrangement includes a riser that extends from a subsea structure to a coupling element for coupling the riser to a vessel. The coupling element includes a buoy body which is connected to a retention member via a flexible connection part. The retention member, such as a submerged buoy, is attached to anchor lines which at or near their end parts are provided with buoy. The connection part, which can be a cable or a frame structure has a relatively high tensile strength to anchor the vessel to the sea bed and to prevent drift of the vessel when tension is exerted on the connection part and the anchor line.
Abstract: A method of rapidly installing a composite pile structure of timber pile sections and a pre-selected connector having an opening smaller than a transverse dimension of a working end of a timber pile section. The lower pile section is driven into the ground to a convenient distance, the connector is driven onto the lower pile and the upper pile driven onto the connector, and the connection is rapidly made rigid.

Abstract: A modular dike is used to divide a body of water into two distinct parts. The modular dike uses a plurality of floatable modules. Each module is floated into the body of water and sunk at predetermined locations in the body of water. The modules are aligned in a row within the body of water so that the row of modules forms a dike which effectively segregates the body of water into two distinct parts.
Abstract: A water structure formed from at least one flexible tube or sleeve, that functions as a water containment vessel when at least partially filled with water and closed at its ends, and includes a rope positioned therein. The rope is for connection, on one end, to a second flexible tube or sleeve and is for use in pulling the second flexible tube or sleeve through the first tube or sleeve. The second tube is then to receive a volume of water therein, that expands the second tube against the first tube inner surface to function as a water structure.
Abstract: A machine for making bored piles. The machine includes a vertical guide mast; a rotary drive head that is movable relative to the mast; and an auger having a hollow core and at least one helical blade. An extender tube has a bottom end that is secured to the top end of the auger, the drive head co-operating with the extender tube to rotate both the extender tube and the auger. A dip tube is slidably mounted in the hollow core of the auger and the extender tube, the dip tube having a top end connected to a concrete feed pipe. An annular actuator has a first end secured to the top end of the extender tube and a second end secured to the top end of the dip tube.
Abstract: Volatile organic compounds are removed from contaminated soil by introducing one or both of a water soluble peroxygen compound, such as a persulfate, and a permanganate into the soil, either in situ or ex situ, in amounts and under conditions wherein both the soil oxidant demand is satisfied and volatile organic compounds in the soil are oxidized. In a preferred embodiment, when both are used, the peroxygen satisfies the soil oxidant demand and the permanganate oxidizes the volatile organic compounds. Sodium persulfate is the preferred persulfate and potassium permanganate is preferred permanganate. The persulfate and the permanganate may be added to the soil sequentially, or may be mixed together and added as an aqueous solution.
