20090165874 | HYDROCARBON TRANSFER SYSTEM WITH VERTICAL ROTATION AXIS - A hydrocarbon transfer system includes a first structure with a length direction and a transverse direction having a frame carrying a vertical arm with at its end a fluid connecting member for connecting to a second structure which is moored alongside the first structure. The connecting member includes a winch and first guiding elements for engaging with second guiding elements on the second structure by connecting a wire to the winch on one end an to the second structure on the other end, and a tension device for moving the vertical arm away from the second structure for tensioning the wire. | 07-02-2009 |
20100104373 | Riser Installation Method from an Offshore Production Unit - A riser installation method including the steps of providing a first vessel situated over a hydrocarbon well, supporting a hydrocarbon transfer duct from the first vessel by a first end that is attached to a lowering device on the first vessel, and attaching a second end of the hydrocarbon duct to a second vessel, at a position near the first vessel. The method also includes the steps of lowering the transfer duct, increasing the distance of the second vessel from the first vessel, pulling the transfer duct until the second vessel is near the third vessel, contacting a section of the transfer duct with the sea bed, displacing the second end of the transfer duct from the first vessel, returning the second end of the transfer duct to the mooring position, and bringing the second end of the hydrocarbon transfer duct in fluid communication with the third vessel. | 04-29-2010 |
20100175606 | OFF-SHORE STRUCTURE, A BUOYANCY STRUCTURE, AND METHOD FOR INSTALLATION OF AN OFF-SHORE STRUCTURE - A buoyant submersible structure floating above the sea floor includes a support portion to support a load, and a gas-filled tank. The tank has an opening, and a connected tube. The tube is partially filled with seawater defining a water-gas interface at a first level. In operation, the structure is fully submerged below the water surface to a first depth. The second chamber is partially filled with seawater defining a water-gas interface at a first position inside the second chamber. Then, the buoyancy structure is moved to a second, greater depth. Water enters the second chamber to raise the water-gas interface to a second, higher level and without entering the first chamber. Subsequently, the buoyancy of the structure is adjusted to tension the cable, a support structure to support a load is attached to the structure, and then the buoyancy of the structure is readjusted. | 07-15-2010 |
20100288374 | SPLIT VALVE - Valve assembly including a first and second valve components in fluid connection with respective first and second ducts, each valve component having a housing and a closure member, a first closure member having a pivot axis extending transversely to the first duct, the first closure member being pivotable between closed and open positions. The first and second closure members each have a coupling element releasably interconnecting the closure members, so the second closure member can be moved with the first closure member upon pivoting of the first closure member around the pivot axis, the second closure member including connector element for engaging with a complementary connector element on the second housing in a closed position of the second closure member, which connector element maintains the second closure member in a non-pivotable sealed attachment with the second housing when the valve components are separated. | 11-18-2010 |
20110033244 | LONG DISTANCE SUBMERGED HYDROCARBON TRANSFER SYSTEM - A hydrocarbon transfer system includes a first and second floating structure and a substantially horizontal transfer pipe system submerged below water level interconnecting the floating structures. The transfer pipe system includes a flow line support member which is with at least one end attached to a connection head, a number of hydrocarbon flow lines being connected along the support member via carrier members. The connection head includes a cable or chain connected to one of the floating structures, connectors situated on the connection head or at the position of the support member near the connection head, which connectors are on one side in fluid connection with the flow lines and on the other side in fluid connection with a flexible flow line extending from the connection head to the floating structure. | 02-10-2011 |
20110048567 | Fluid-Tight end fitting for a Composite Hose and Method of Assembling a Composite Hose on Such end Fitting - A composite hose includes a tubular body of flexible material for transferring cryogenic fluid through the hose and for preventing fluid leakage through the body. The tubular body includes an inner wire helix spirally wound along the length of the hose, an outer wire helix spirally wound along the length of the hose, at least two reinforcing layers placed in between the inner and outer wire, at least one sealing layer placed between two reinforcing layers, an end fitting at both ends of the tubular body, each end fitting provided with a part for connection to another hose flange and an elongated cylindrical part, which is divided in an anchoring area for anchoring the tubular body and a static sealing area for fluid tight sealing of the hose. A gas tight sealing is created by bonding the at least one sealing layer to the cylindrical part over a ring shaped bonding area. | 03-03-2011 |
