A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame and a second frame each spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart.

The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. An object that has been salvaged can be placed upon the vessel.

A method is provided for removing an abandoned marine platform from a seabed. The platform extends below the seabed mud line. In order to remove the platform, a frame is provided having a perimeter that surrounds an open center. The frame is lowered over the platform wherein the platform occupies the open center portion. A movable cutter cable is fitted to the frame. At least a part of the cutter cable is positioned below the mud line. The cutter is moved relative to the frame to cut the platform below the mud line. Such movement can be a back and forth movement wherein the cutter cable moves in a first direction, stops and then moves in a second direction that is generally opposite the first direction. A lifting device can employ two vessels and two frames, each frame bridging from one vessel to the other. Winches on the vessel can be used to provide movement to the cutter cable. These same winches can take up cable slack as cutting moves from one platform member (e.g. leg, jacket leg, piling, etc) to another.

Articulated multiple buoy marine platform apparatus and method of installation
A marine platform (and method of installation) provides a plurality of buoys of special configuration, a platform having a peripheral portion that includes a plurality of attachment positions, one attachment position for each buoy, and an articulating connection that connects each buoy to the platform at a respective attachment position, the connection allowing for sea state induced buoy motions while minimizing effect on the platform. A method of installation places the platform (including oil and gas drilling and/or production facility) next to the buoys. Ballasting moves the platform and buoys relative to one another until connections are perfected between each buoy and the platform.
A method of elevating the deck area of a marine platform (e.g., oil and gas well drilling or production platform) utilizes a specially configured sleeve support to support the platform legs so that they can be cut. Once cut, rams or jacks elevate the platform above the cuts. The sleeve support is then connected (e.g., welded) to the platform leg and becomes part of the structural support for the platform. In one embodiment, two sleeves are employed. In another embodiment, the jacks or rams elevate in two stages including a first stage wherein one sleeve elevates and the other sleeve does not elevate and a second stage wherein both sleeves elevate together.

Method and apparatus for salvaging underwater objects
A method and apparatus for removing debris from an ocean floor or seabed employs a subsea debris basket. The basket eliminates the absolute necessity of a cargo barge or any other supporting vessel that might be required to remain in a field until the objects on the ocean floor can be lifted. The present invention provides a non-weather sensitive solution. The present invention affords the safe operation in that all lifting and lowering is performed in a subsea environment next to the ocean floor or seabed. The present invention enables operation to be completed with the use of an ROV or remotely operated vehicle. The present invention provides improved offshore efficiency, less time being required to recover debris from the seabed to the underwater salvage basket or debris basket. The present invention enables the possibility of use of an A-frame or simple crane to lower debris into a subsea basket. The basket can be reused or redeployed in the field if desired. The basket may also be “reefed” in place to address the stability concerns of small debris and to minimize transit time of debris to a reef site.

Each of the frames extends upwardly in an inverted u-shape, providing a space under the frame and in between the barges that enables a marine vessel to be positioned in between the barges. An object that has been salvaged from the seabed can be placed upon the marine vessel.
