Abstract: A sock for a floating platform including a plurality of tubulars coupled together and defining a bore and a catcher assembly. The catcher assembly including a plurality of orifices formed in at least one of the plurality of tubulars, a catcher releasably coupled to the plurality of tubulars by a plurality of shearable members, wherein the catcher is disposed in the bore, and wherein the catcher is movable from a first position to a second position, and a stop flange having at least one aperture.

Abstract: An apparatus for use in marine platform jacking is disclosed herein. In one aspect, a jetting valve includes a valve body with a piston assembly disposed therein. The piston assembly is selectively operated to open and close the valve. A biasing member is coupled to the piston assembly. The piston assembly includes a first piston and a second piston. The dual pistons, in cooperation with the biasing member, allow the valve to self-seal thereby preventing entry of a fluid which is external to the valve.

Abstract: The present disclosure generally relates to movable offshore platforms for installing wind turbines, and methods of forming the same. The movable offshore platforms are offshore platforms which were previously used in hydrocarbon production, such as jack-up units. The movable offshore platforms may be decommissioned and retrofitted with equipment for installing wind turbines. The movable offshore platforms may be American-made or otherwise Jones Act compliant. Methods of forming the same are also included.

Abstract: The present disclosure generally relates to an apparatus for storing, treating, and making up of various drilling fluids onboard a dynamically positioned vessel, such as a barge, boat, or shop. In particular, the present disclosure relates to a liquid mud plant (LMP) supporting any offshore drilling rig or platform from a vessel in closer proximity to that rig. Additionally, the present disclosure relates to the process by which the liquid mud plant is in closer proximity to the drilling, which is derived from the dynamical positioning capability of the liquid mud plant vessel.

Abstract: The present disclosure generally relates to jack-up units employing a multi-purpose derrick structure for drilling, plug, abandonment, and decommissioning operations. The multi-purpose derrick structure includes a mast that may be vertically oriented in a first configuration to facilitate drilling, plug, and abandonment procedures, or may be pivotably positioned in a second configuration for decommissioning operations or other procedures. In the pivoting position, the mast functions as a heavy lift crane. One or more selective pivoting structures at the base of the multi-purpose derrick structure, and one or more actuators, facilitate the multiple uses of the multi-purpose derrick structure.

Abstract: The present disclosure generally relates to marine rig equipment, and specifically to a mobile jackup rig having one or more moveable cranes. The one or more moveable cranes are configured to operate along a rail, and the one or more moveable cranes are positioned to reach more than one work site location. In one embodiment, a mobile jackup rig includes at least one two-rail system having a first guide-track rail and a second guide-track rail, and at least one moveable crane positioned to operate along the two-rail system. In another aspect, a mobile jackup rig may include at least one moveable pedestal crane positioned on at least one curved or straight guide-track rail system.

Abstract: A taut mooring system for use on a mobile offshore jack-up platform while it is in an elevated operating condition. The elevated operating condition is with the hull jacked up a safe distance above the highest anticipated wave crests, on vertically movable legs which extend to the ocean floor. The mooring system consists of: radially spaced mooring line attachment means on the structure of the platform; suction piles that are radially spaced around the platform, consistent with the radial spacing of the mooring line attachment means; and taut mooring lines which radially connect the suction piles to the attachment means. The flexibility of the taut mooring system provides the ability to coact with the platform's free standing storm resistance capabilities, yielding enhanced capabilities that will enable the platform to safely resist storm induced forces that the platform would not normally be capable of withstanding, and to enable the platform to be used with longer legs in deeper water.
