Patent number: 6983714Abstract: In a method of and apparatus for offshore mooring, a clamping apparatus includes a clamping mechanism and a pulley. A mooring line connected to an anchor or a pendant line connected to a vessel to be moored extends through the clamping mechanism and around the pulley of the clamping apparatus. The distal end of the line extending through the clamping apparatus is connected to an anchor handling vessel. The anchor handling vessel is employed to apply a predetermined tension to the pendant line and the preset mooring line. A remote operated vehicle is then employed to actuate the clamping apparatus and to disengage the anchor handling vessel.Type: GrantFiled: June 15, 2001Date of Patent: January 10, 2006Assignee: Technip FranceInventors: Peter G. S. Dove, Johannes Jacobus Treu

Patent number: 6309269Abstract: In a system for mooring offshore drilling units, a first mooring assembles installed at a first drilling venue, after which the mobile offshore drilling unit is moored by connection to the mooring lines. A second mooring assembly is installed at a second drilling venue while drilling operations are carried out at the first drilling venue. In this manner the mobile offshore drilling unit can be relocated between successive drilling venues with minimum down time. Less than complete mooring assemblies can be used to temporarily secure the mobile offshore drilling unit.Type: GrantFiled: May 7, 1999Date of Patent: October 30, 2001Assignee: Aker Marine, Inc.Inventors: Thomas M. Fulton, Peter George Scott Dove, Gordon R. Wilde, Johannes Jacobus Treu

Patent number: 6132145Abstract: A pumpskid comprises a frame adapted for connection to a remotely operated vehicle for positioning thereby. A male connector mounted on the frame is adapted for engagement with the suction port on a suction anchor. Clamping apparatus is provided for securing the male connector in engagement with the suction port of the suction anchor and thereby clamping the pumpskid in engagement with the suction anchor. A pump mounted on the frame is connected in fluid communication with the male connector by piping sections which include a port open to the surrounding sea. Valves and valve actuators are provided for causing the pump to cause water flow out of or into the suction anchor, as required.Type: GrantFiled: April 30, 1999Date of Patent: October 17, 2000Assignee: Aker Marine, Inc.Inventors: Johannes Jacobus Treu, Thomas M. Fulton, Francis Wade Abadie, Frederick Howard Culver

Patent number: 6003466Abstract: An anchor installation vessel transports anchors and mooring lines to an installation site and installs the anchors at diametrically opposed points in an anchor array. Following installation the mooring lines are directed to the vessel from opposite sides and are preloaded using winches mounted on the vessel.Type: GrantFiled: February 5, 1998Date of Patent: December 21, 1999Assignee: Aker Marine Contractors, Inc.Inventors: Peter George Scott Dove, Johannes Jacobus Treu

Patent number: 5992060Abstract: In a method of and apparatus for anchor installation, a plate anchor is mounted at the bottom of a suction follower comprising a hollow cylinder having an open lower insertion end and a closable upper suspension end. The suction follower and the anchor secured thereto are engaged with the sea floor, whereupon water is pumped out of the suction follower causing the suction follower and the anchor to penetrate into the sea floor to a predetermined depth. The anchor is then disengaged from the suction follower, whereupon water is pumped into the suction follower to disengage the suction follower from the sea floor for recovery to the surface, leaving the anchor embedded in the sea floor.Type: GrantFiled: November 17, 1997Date of Patent: November 30, 1999Assignee: Aker Marine, Inc.Inventors: Johannes Jacobus Treu, Peter George Scott Dove, Gordon R.

Patent number: 5855178Abstract: A taut leg bow mooring system includes an anchor positionable on the floor of the sea. A riser line is normally secured to and extends upwardly from the anchor, and a submerged buoy is secured to the end of the riser line remote from the anchor. A line extends upwardly from the submerged buoy to a surface buoy. A mooring line is pivotally connected in the line extending from the submerged buoy to the surface buoy.Type: GrantFiled: October 30, 1997Date of Patent: January 5, 1999Assignee: Aker Marine, Inc.Inventors: Johannes Jacobus Treu, Peter George Scott Dove

Patent number: 5704307Abstract: A taut leg bow mooring system (40) includes an anchor (42) positionable on the floor of the sea. A riser line (44) secured to and extending upwardly from the anchor, and a submerged buoy (46) secured to the end of the riser line from the anchor. The ratio of the net buoyancy of the surface buoy to the buoyancy of the submerged buoy is at least 2 to 1. A buoyant connector line (50) is secured to and extends upwardly from the submerged buoy. A surface buoy (52) is secured to the end of the connector line remote from the submerged buoy, and a hawser (56) is secured to and extends from the surface buoy.Type: GrantFiled: November 8, 1996Date of Patent: January 6, 1998Assignee: Aker Marine, Inc.Inventors: Johannes Jacobus Treu, Peter George Scott Dove
