Patent number: 9851141Abstract: A method is provided for operating a system for the liquefaction of gas of the type comprising a main heat exchange vessel, a bundle for the gas to be liquefied extending through said MCHE and a refrigerant compression circuit of which a first end leads evaporated refrigerant from the vessel towards a compressor and a second end supplies the compressed and cooled refrigerant from the compressor towards the MCHE. For avoiding problems during heat up or during start up of the heat exchanger the pressure within the liquefaction system is controlled by regulating the amount of evaporated refrigerant in the liquefaction circuit.Type: GrantFiled: July 2, 2009Date of Patent: December 26, 2017Assignee: BLUEWATER ENERGY SERVICES B.V.Inventors: Pieter Cornelis Burger, Clemens Gerardus Johannes Maria Van Der Nat, Jozefus Gerardus Petrus Vernooij

Patent number: 9097374Abstract: An assembly for transferring fluids between a vessel and a turret structure mounted in said vessel for a rotation around a substantially vertical turret axis is provided. Said turret structure comprises a swivel having at least one fluid path which is connected with one end of a fluid piping of which the second end is connected to the vessel. A swivel tower mounts around the swivel and engages the remainder of the turret structure by a swivel tower bearing. A torsion lock mechanism substantially locks the swivel tower to the vessel for a rotation therewith. A first fluid piping segment extends freely between the vessel and the swivel tower and a second fluid piping segment extends between the swivel tower and the fluid path of the swivel. The segments are joined at an interconnection where the fluid piping is substantially fixed to the swivel tower by fixing device.Type: GrantFiled: March 7, 2014Date of Patent: August 4, 2015Assignee: Bluewater Energy Services B.V.Inventor: Clemens Gerardus Johannes Maria Van Der Nat

Patent number: 8651040Abstract: A disconnectable mooring system for a vessel is presented, comprising a moonpool in the vessel, a turret structure mounted for a rotation in said moonpool and a buoy member having a plurality of passages each adapted to receive a riser. The turret structure has a lower end comprising a buoy receptacle for detachably receiving the buoy member, wherein the mooring system further comprises a plurality of mooring lines for transmitting mooring forces and each have a lower end and an upper end connected to the seabed and the buoy member, respectively. The mooring lines each comprise a first section which in a disconnectable manner is connected to the turret structure and a second section connected to the first section at a coupling point and connected to the buoy member. Also methods for disconnecting and reconnecting such a mooring system are presented.Type: GrantFiled: February 22, 2012Date of Patent: February 18, 2014Assignee: Bluewater Energy Services B.V.Inventors: Rik Robert Heideman, Patrizio Giovanni Matia Ottolini, Clemens Gerardus Johannes Maria Van Der Nat, Boris Rijnten, Richard Leeuwenburgh, Jacob Jan Van Nielen, Henk Heikens Pleizier

Patent number: 7527010Abstract: Vessel with mooring system, comprising a turret anchored to the seabed and a turret casing being part of the vessel, wherein the turret and turret casing are interconnected by a connecting element comprising a bearing arrangement and wherein the connecting element has a first end connected to the turret casing and an opposite second end connected to the turret. The connecting element is positioned in such a manner that it experiences tensile forces. When the turret downwardly loads the turret casing the first end of the connecting element is positioned at a higher level then the second end thereof. When the turret upwardly loads the turret casing the first end of the connecting element is positioned at a lower level then the second end thereof.Type: GrantFiled: August 3, 2007Date of Patent: May 5, 2009Assignee: Bluewater Energy Services B.V.Inventors: Rik Robert Heideman, Hendrik Cornelis Ynze Ter Horst, Clemens Gerardus Johannes Maria Van Der Nat, Pieter Cornelis Burger
