  • Patent number: 10280055
    Abstract: A lifting assembly for lifting a load including a frame and a rotation member. The frame includes a central portion interconnecting two spaced apart lifting portions and a suspension space defined below the central portion and between the lifting portions. The central portion includes an aperture. Each lifting portion is configured to engage a lifting device, such as a fork lift. The rotation member is disposed above the aperture of the central portion. The rotation member is a ball joint including a ball member that rotates and pivots within a rotation cavity. A fastener member attaches to the ball member and is suspended through the aperture of the frame's central portion. The fastener member is attached to a load to lift and suspend the load within or below the suspension space while allowing rotation and pivoting of the load relative to the frame.

  • Patent number: 10167677
    Abstract: A flotation system includes one or more floatation modules, each having a first section and a second section, each having an internal core made of a buoyant material. The first section includes two end faces and a projection extending from one of the end faces. The projection has a contoured profile. The second section includes two end faces and a reciprocal recess in one of the end faces. The end faces of the first section engage the end faces of the second section such that the projection engages the reciprocal recess in a mating engagement. The outer surface of the flotation module include one or more grooves providing a pathway for the flow of circulation fluid. The floatation system may be attached to a tubular string during inner string cementing operations to reduce the load applied to the platform.

  • Publication number: 20080289829
    Abstract: An apparatus for reducing the load applied to a rig. The rig is positioned over a well, with the well having a tubular string disposed therein. A landing string is connected to the tubular string such as casing, production and/or testing assemblies. The apparatus comprises a floatation module attached to the landing string and a clamp for clamping the floatation module onto the landing string. In one embodiment, the floatation module comprises a tubular sleeve having a buoyant material applied thereto. The tubular sleeve includes slots. The clamp may contain a set of dies adapted to engage the slots of the tubular sleeve. A method of landing a work string into a sub-sea well head from a floating drilling rig is also disclosed, wherein a marine riser connects the rig to the sub-sea well head.
