摘要： A compliant offshore structure in which the primary restoring force to lateral displacement is provided by elongate flex elements. A gravity base is rigidly secured to the ocean bottom. A tower extends vertically upward from the base to a position above the ocean surface. A work deck is supported atop the tower. The tower is secured to the base by elongate flex elements which are arranged in an array surrounding the central axis of the structure. Each flex element has one end secured to the base and a second end secured to the tower. The flex elements permit the tower to pivot about its lower end, thus providing the tower and deck with a compliant response to environmental forces. The flex elements also support the tower above and free from contact with the base. This eliminates the need for a vertical load bearing joint between the tower and base.

摘要： A mobile, year-round drilling system (MYADS) for drilling offshore wells and/or performing other offshore activities at multiple, successive locations in an arctic or sub-arctic environment is provided. The present invention combines the ability to move to different locations and the strength to resist ice loading when on location and when ice-covering is present in the arctic or sub-arctic environment. The MYADS applies a multiple leg “jack-up” concept in which supporting legs are lowered through a hull to touch down on the seabed and elevate the hull out of the water.

摘要： This invention provides a method for constructing an offshore platform by mating a self-floating deck structure with a self-floating substructure. The self-floating deck structure may be a floating pier or barge, on which the desired equipment has been mounted. Mating is achieved by at least partially submerging the substructure, positioning the pier or barge above it, and deballasting the substructure to create a vertical bearing force between the substructure and the pier or barge. Horizontal force may be transmitted between the deck and substructure by a variety of mechanical, structural, and magnetic means.

摘要： An apparatus and method for installing a deck on an offshore substructure is provided. The apparatus comprises a deck supported by lifting mechanisms that are in turn attached to pontoons. The apparatus floats on the water with the lifting mechanisms compressed until transported to an offshore substructure having an upper end located above the water surface. The lifting mechanisms are then extended and the apparatus moved on the surface of the water to position the deck over the substructure. The deck is then lowered onto the substructure and the pontoons are lifted out of the water.

摘要： An offshore structure which is resistant to wave, earthquake and ice loads and can be quickly installed and abandoned in response to changing environmental conditions includes a caisson having an upper section and a lower foundation section which are separated by a structural diaphragm. When installed, the lower foundation section extends downwardly a distance from the seafloor to provide sufficient lateral and vertical soil resistance to resist lateral and vertical loads on the structure. The upper section is adapted to support a deck structure. The structural diaphragm is adapted to rest on the seafloor when an offshore structure has been fully installed to enhance the lateral and vertical load carrying capacity of the offshore structure. During installation, the structural diaphragm and a pump are used to form suction in the lower foundation section, thus enhancing the penetration of the lower foundation section into the seafloor.

摘要： An improved apparatus is disclosed for setting a deck structure or other marine superstructure using a barge mounted cantilevered support structure. The cantilevered support structure is attached at one end of a floating vessel. The cantilevered support structure extends past the edge of the vessel and, in one embodiment, includes means for rotating parallel support members about the deck of the floating vessel permitting the cantilevered support structure to be raised and lowered while it remains substantially parallel with the top of the offshore platform enabling the superstructure to engage the top of a previously installed offshore platform in a synchronized manner. Alternatively, this superstructure may be aligned directly over the platform. A cantilevered drilling rig is then aligned over the cantilevered support structure and used to lift the deck structure or marine superstructure, permitting the vessel and cantilevered support structure to move. The drilling rig is then used to lower the marine superstructure onto the top of the previously installed offshore platform.

摘要： An articulated, compliant offshore structure having a base portion establishing a gravity-type foundation on the ocean bottom, a tower extending upward from the base portion and a deck seated on the tower a spaced distance above the ocean surface. The tower is secured to the base portion by an articulated joint which permits the tower and deck to undergo limited pivoting about the base. This provides compliancy in response to forces imposed on the structure by wind, waves and ocean currents. A set of tensioned members, preferably cables, are secured between anchorages on the base and at an elevated position on the tower to provide controlled resistance to pivoting of the tower. In the preferred embodiment the tower and base are concrete shell structures.
