Publication number: 20130101357Abstract: The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with a lower portion that is an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration. Furthermore, the ice worthy jack-up rig that comprises at least two derricks so as to double the exploration efficiency and lower the relating costs.Type: ApplicationFiled: February 14, 2012Publication date: April 25, 2013Applicants: Keppel Offshore & Marine Technology Centre PTE Ltd., ConocoPhillips CompanyInventors: Peter G.

Patent number: 8425171Abstract: A racking assembly for receiving and storing at least one pipe. The racking assembly comprises a set back assembly including a selectively rotatable member having a plurality of radial slots sized for receiving a portion of the pipe(s) in sliding engagement, and a base for supporting the pipe(s). The base is coupled to the selectively rotatable member so as to permit mutual rotation. A barrier is located about a peripheral edge of the base, such that the setback assembly rotates relative to the barrier. The barrier is arranged to prevent the pipe(s) from moving radially from the base. The barrier has a gap sized to permit selective lateral movement of the pipe(s). Mutual rotation of the selectively rotatable member and the base permit alignment of the gap and a selected slot of the selectively rotatable member, and thus permits the pipe stands to be moved laterally into the setback assembly.Type: GrantFiled: November 11, 2011Date of Patent: April 23, 2013Assignee: Keppel Offshore & Marine Technology Centre Pte Ltd.Inventors: Asbjørn Mortensen, Kok Seng Foo, Rune Henriksen, Yeong Jin King

Publication number: 20110305521Abstract: Pre-assembled self installing platforms with improved performance due to additional rotational restraint to supporting legs and methods of installation. The platform includes a hull, legs movable relative to the hull, at least one brace frame movably connected to at least two of the legs. Upon installation, the brace frame may be positioned at a desired elevation and rigidly secured to the legs, providing rotational restraint to significantly reduce leg stress and increase rigidity of the legs. With the increased rigidity, it becomes possible to install platforms in relatively deep waters and harsh environments, and yet preventing large overall platform sway induced by adverse weather or sea conditions. As the brace frame is securable to the legs after the legs or footings are penetrated into or supported on the sea bed, differential penetration of legs or footings into the seabed becomes possible without risking large structural loads in the brace frame.Type: ApplicationFiled: June 8, 2011Publication date: December 15, 2011Inventors: Wouter Joachim Henstra, Michael John Perry, Henry Krisdani, Kok Seng Foo, Chin Kau Matthew Quah

Patent number: 8047151Abstract: A system and method for configuring and supporting mooring lines deployed on offshore structures, e.g. Spar-type platform, are provided with recessed portions that are located around the splash/ice zones for “cutting” through waves. An offshore structure may be provided with a chain tensioning mechanism that applies a desired tension to a hull chain and mooring line during mooring. Upon mooring the offshore structure, a chain lock mechanism maintains the tension in the hull chain and mooring line, while the chain tensioning mechanism releases a portion of the hull chain which is to be stored in a chain housing which is fully submerged underwater. This way, the recessed portions of the offshore structure around the splash/ice zones would be substantially free of the hull chains. Additionally, a disconnect mechanism may be provided to allow quick and safe disconnection of the offshore structure from the mooring position.Type: GrantFiled: July 29, 2009Date of Patent: November 1, 2011Assignees: Keppel Offshore & Marine Technology Centre Pte Ltd, Offshore Technology Development Pte LtdInventors: Kok Seng Foo, Asbjorn Mortensen, Rune Henriksen, Chai Wah Koh, Toh Tung Wong

Patent number: 8025463Abstract: The present invention describes an offshore foundation system (10,10a,10b) that is operable for preloading after self-weight installation on a seabed without relying on additional or external ballasts. The foundation system (10,10a,10b) is also operable for extraction by reversing the process of preload operation. In one embodiment, the foundation system (10) comprises a reaction base (20) and suction compartment (60). In another, the foundation system (10a,10b) comprises a plurality of units of reaction base (20) and suction compartments (60), with the units being connected by bridging structures (21). In yet another, the foundation system comprises a reaction base (20) and a plurality of suction compartments (60). A closed-top of the suction compartment (60) projects above the reaction base (20) so that, in use, there is a gap h between a top of a soil plug inside a suction compartment (60) and its closed-top.Type: GrantFiled: May 28, 2009Date of Patent: September 27, 2011Assignees: Keppel Offshore & Marine Technology Centre Pte Ltd, University of Western AustraliaInventors: Kok Seng Foo, Chin Kau Quah, Okky Ahmad Purwana, Mark Jason Cassidy, Christophe Rene Henri Gaudin

Patent number: 8011857Abstract: The present invention describes an extraction system (100,100a) for expediting removal of a footing (105) that is embedded in a seabed or marine floor. The extraction system provides a supply of pressurized fluid (140) to a chamber from where the pressurized fluid exudes through porous members (122,122a, etc) located on the base (114) of the footing (105). When an uplifting force is applied to the footing (105) for its removal, the pressurized fluid (140) exudes out through the porous member (122,122a, etc.) to compensate or reduce suction induced beneath the footing, without fluidizing or channeling of the seabed soil, thereby expediting removal of the footing (105).Type: GrantFiled: May 26, 2009Date of Patent: September 6, 2011Assignees: Offshore Technology Development Pte Ltd, National University of SingaporeInventors: Kok Seng Foo, Chin Kau Quah, Okky Ahmad Purwana, Yean Khow Chow, Chun Fai Leung
