A method for laying cable from a vessel at a near shore location in shallow water to shore. The cable on the vessel is wrapped around a modified roller quadrant on the vessel. The roller quadrant is moved from the vessel into the water. A pulling device is attached by a line to the roller quadrant. The pulling device is used to pull the roller quadrant and cable toward shore. The pulling device may be positioned in the water and moved to shore as required. The pulling device may also be initially positioned on shore. The roller quadrant may include a skid and buoyancy modules to reduce the pulling force required to move the roller quadrant and lay the cable to shore.
An ultrasonic transducer arrangement for inspecting a pipe to fitting weld with restricted scanning access. A TOFD ultrasonic send transducer is mounted adjacent one end of a frame. A TOFD ultrasonic receive transducer is mounted on the frame and spaced linearly apart from and aligned with the TOFD send transducer. The TOFD send and receive transducers are each positioned at an angle that matches the external radius of curvature of the pipe. A phased array curved, wedge, send/receive transducer is mounted on the frame and spaced radially apart from the TOFD transducers.
An arrangement of elements which are used to restrain and deflect a pipe specimen to a prescribed form with precisely controlled loads. A rigid frame includes a movable pipe bending form to which one end of a pipe specimen is connected and a rotating table to which the second end of the pipe specimen is connected. Means for assessing the drive torque used to draw the pipe specimen over the pipe bending form is provided in the form of a load cell. The rotating table is used in combination with a travelling pipe end truck foundation to generate a bending moment in the pipe specimen in the same plane as the pipe specimen is being bent by the pipe bending form. By the use of precise loads on the pipe specimen, computer analysis of the simulated reeling of the given pipe construction will produce predictions of the reeling tension, shear, and bending moment in the pipe at the point of the travelling pipe end as this point on the pipe approaches contact with the reel.

A load out and float off method for a spar type structure or another structure such as a deck. The invention enables the load out and float off of a large diameter spar using existing Heavy Lift Vessels (HLV's). A U-shaped tank (U-tank) is utilized to artificially extend the length of the HLV and provide supplemental buoyancy to help lift the spar off the land ways. The U-tank provides supplemental buoyancy and water plane area to float the spar off the HLV. After HLV departure the U-tank is moved and placed beneath an adapter frame on the spar's hard tank. The U-tank is ballasted upward to reduce the hard tank draft and have the strake tips clear the channel bottom. The spar can then be brought alongside the fabrication yard quay for additional work and then towed down the channel to the open sea.

The invention enables the load out and float off of a large diameter spar using existing Heavy Lift Vessels (HLV's). A U-shaped tank (U-tank) is utilized to artificially extend the length of the HLV and to provide supplemental buoyancy to help lift the spar off the land ways during load out. The U-tank provides the necessary supplemental buoyancy and water plane area to float the spar off the HLV. After the departure of the HLV the U-tank is moved and placed beneath an adapter frame cantilevered off the top of the spar's hard tank. The U-tank is ballasted upward to lift the hard tank and reduce its draft. At the reduced draft of the hard tank the strake tips clear the channel bottom. Because the strake tips clear the channel bottom, the spar can be brought alongside the fabrication yard quay for additional work. Subsequently, at the reduced draft, the spar can be towed down the channel to the open sea.
A reeled pipe storage reel with a large diameter hollow cylindrical shaft, reel shaft bearing support structures installed on the vessel, and a reel drive arrangement mounted on the vessel. The shaft across the width of the reel provides structural stiffness and consistent alignment of the bearings on each end of the shaft. Each end of the shaft extends beyond the reel and includes a section for connection to a lifting sling, a section for the machine bearing surface, and a section for absorbing initial contact with the vessel during installation. The reel shaft bearing support structures on the vessel include a fixed portion to match the bearing area of the reel shaft and a movable portion to absorb initial contact during installation of the reel. The reel drive arrangement is located on linkages so they can be manipulated in the plane of the reel flange for movement into engagement with the drive gear on the reel flange.
A method of mating of a buoyant hull with a truss structure while at the installation site of the completed offshore structure. The buoyant hull is moored in place. The truss structure is placed in the water, self upends, and maneuvered near the buoyant hull. The buoyant hull and truss structure are rigged with lines to allow the truss structure to be pulled into engagement with the buoyant hull. The truss structure is lowered to a predetermined depth below the water surface but above the sea floor and the weight is transferred to the lines from the buoyant hull. The truss structure is aligned with the buoyant hull and lines from the buoyant hull are used to pull the truss structure into engagement with the buoyant hull. The truss structure and buoyant hull are rigidly attached together as is customary using grouting and welding.
A rigid U-shaped structure sized to be closely received on the tip end of the transfer hook. One side of the U-shape of the structure is closed. A padeye is rigidly attached to the end curved portion of the U-shape of the structure. Means for holding the U-shaped structure in position on the tip end of the hook is provided. The holding means may be threaded bores through one or both sides of the U-shaped structure that allow bolts to be threaded through the holes such that they create sufficient friction against the tip end of the transfer hook to hold the U-shaped structure in position. The holes through the U-shaped structure may be unthreaded with threaded nuts rigidly attached to the U-shaped structure such that the nuts are aligned with the holes to allow bolts to exert pressure against the tip end of the transfer hook in the same manner to hold the U-shaped structure in position on the transfer hook.

A mechanically releasable shackle pin arrangement that is readily operated by an ROV and is not affected by the hydrostatic pressures encountered at depth. A shackle body having two ends has a shackle pin received through bores at one end of the shackle body. A shackle nut threaded on the shackle pin secures the shackle pin in an installed position through the bores in the shackle body. An anti-rotation link plate is attached to the shackle body. The anti-rotation link plate extends to one end of the side plate. The shackle pin extends through bores at one end of the shackle body and the anti-rotation link plate and is secured in its installed position by a shackle nut threaded on the shackle pin. Means for preventing rotation of the shackle nut and loss of the shackle nut is provided on the anti-rotation link plate such that the shackle pin can be removed by a remotely operated tool on an ROV at depth to release a load without the need for hydraulics on the shackle assembly. The shackle pin is provided with a special plate arrangement designed to allow the shackle pin to be gripped and rotated by a remotely operated tool on an ROV.
A modified strongback for laying pipeline offshore that utilizes a movable clamp. One end of the strongback is modified to include a travel mechanism . A pipe clamp is mounted on the travel mechanism to allow movement of the clamp as necessary to accommodate different pipe joint lengths. A mechanism for locking the clamp in the desired position is provided on the strongback.
