Publication number: 20110182698Abstract: Methods and systems disclosed provide a cost efficient supply chain for natural gas, thereby enabling monetization of smaller natural gas sources and supply of natural gas to regions with low demand. The method comprises transferring a hydrocarbon fluid to a production location, liquefying the hydrocarbon fluid, storing the hydrocarbon fluid in a plurality of transferable containers, moving the plurality of transferable containers having the hydrocarbon fluid from the production location to a marine vessel, transporting the plurality of transferable containers having the hydrocarbon fluid on the marine vessel, and offloading the hydrocarbon fluid at an import location. At the import location, the transferable containers may be moved from the marine vessel to the import location and distributed at least one vehicle from the import terminal to one or more user locations for vaporizing the liquefied fluid at the user location(s).Type: ApplicationFiled: October 9, 2009Publication date: July 28, 2011Applicant: Keppel Offshore & Marine Technology Centre PTE LTDInventors: Kok Seng Foo, Hee Yan Yip, Wen Sin Chong, Yun Shui Chen

Patent number: 7726910Abstract: A leg guide for use in a leg of a jack up unit adapted to provide sliding guidance of the leg during vertical movement of the leg. The leg guide has a first portion contacting an edge of a leg chord and a second portion contacting a face of the leg chord along a longitudinal plane opposite the contact plane of the first portion. The edge contacting guide has a deflecting guide unit, which uses a compressible member sandwiched between two rigid plates. As the leg moves, the teeth of the leg chord contact the edge guide unit, with the compressible member absorbing compressible loads acting on the leg chord. The second portion provides for a face plate mounted transversely to the edge contacting guide for reducing the build-up of horizontal moment acting on the leg chord during the vertical movement of the leg and for reducing bending moments acting on the leg.Type: GrantFiled: March 11, 2008Date of Patent: June 1, 2010Assignee: Offshore Technology Development Pte Ltd.Inventors: Kok Seng Foo, Chin Kau Matthew Quah, Cheng Choong Chan

Publication number: 20100096068Abstract: A method of protecting and repairing surfaces of structures using hand-laid epoxy and glass-aramid fabric composite is taught. Unlike the use of such composites as structural members, the present invention makes use of such composites in novel and inventive applications. Also unlike other methods, the invention is carefully hand-laid to conform closely to any irregular surfaces on the structure to be protected or repaired. The product of the method of the present invention is tougher than conventional paints and coatings and lasts significantly longer than conventional paints and coatings.Type: ApplicationFiled: December 23, 2009Publication date: April 22, 2010Applicant: OFFSHORE TECHNOLOGY DEVELOPMENT PTE LTDInventors: Kok Seng Foo, Chin Kau Quah

Publication number: 20100024706Abstract: 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: ApplicationFiled: July 29, 2009Publication date: February 4, 2010Applicants: Keppel Offshore & Marine Technology Centre Pte. Ltd., Offshore Technology Development Pte. Ltd.Inventors: Kok Seng FOO, Asbjorn MORTENSEN, Rune HENRIKSEN, Chai Wah KOH, Toh Tung WONG

Publication number: 20090297276Abstract: 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: ApplicationFiled: May 28, 2009Publication date: December 3, 2009Applicants: 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

Publication number: 20090269144Abstract: 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: ApplicationFiled: May 26, 2009Publication date: October 29, 2009Applicants: Offshore Technology Development Pte Ltd, National University of SingaporeInventors: Kok Seng FOO, Chin Kau QUAH, Okky Ahmad PURWANA, Yean Khow CHOW, Chun Fai LEUNG

Patent number: 7186061Abstract: The invention relates to mobile offshore jack-up structures and provides for a self-regulating jacking system for elevating and lowering of the legs and the hull. A central controller assembly regulates movement of each of the legs, depending on the relative speed of movement of each leg and inclination of the hull along two independent axes: forward-aft and starboard-port. Each chord of the supporting legs is inverter driven to ensure a bi-directional full rated torque control of the associated pinion assemblies at very low speeds. By regulating the relative speed of the leg vertical movement, the system monitors the hull inclination within allowable limits and prevents an excessive differential vertical travel of any of the leg chords, thereby minimizing a possibility of leg bending or jamming of the screw jacks of the jacking assemblies 30.Type: GrantFiled: September 15, 2005Date of Patent: March 6, 2007Assignee: Offshore Technology Development Pte Ltd.Inventors: Kok Seng Foo, Chuan Beng Tay

Patent number: 6030149Abstract: The present invention has at least one rack chock which is supported pivotally and tiltably at one end by a pin and cross head assembly located at a position between at least one leg rack and the hull of the platform. The other end of the rack chock is connected to the jack foundation with an actuator assembly. The pin and cross head assembly is disposed slidably within a guide for permitting the teeth of the rack chock to engage the leg rack teeth without visual monitoring and manual control. The actuator assembly connected to the other end of the rack chock controls the swinging movement of the rack chock and its engagement and disengagement with the leg rack. A pair of jacks urges upper and lower wedges with tiltable surfaces converging onto the rack chord's upper and lower surfaces, thus obtaining a optimal surface to arrest the relative movement between the rack chock and the leg rack.Type: GrantFiled: September 26, 1996Date of Patent: February 29, 2000Assignees: Offshore Technology Development Pte Ltd, Amfels, Inc.Inventors: Kok Seng Foo, Govind Raghunath Rege
