Patent number: 10668996Abstract: A structural block is fabricated with necessary components and structure for LNG storage and/or process. The structural block may be an LNG tank with the same configuration as that in an LNG carrier. The structural block may also be a regasification plant or a liquefaction plant to be used for LNG process. An existing vessel, e.g. an LNG carrier, is cut apart to form a forward section and an aft section. The forward section and the aft section are moved away from each other to form a space therebetween. The structural block is then placed into the space and jointed to the forward and aft sections, by welding for example, to form an integrated new vessel. The structural block provides the new vessel with increased LNG storage and transportation capabilities as well as regasification and/or liquefaction process facilities to meet the increased demand for LNG storage, transportation and processing.Type: GrantFiled: January 29, 2013Date of Patent: June 2, 2020Assignee: Keppel Offshore & Marine Technology Centre Pte LtdInventors: Asok Kumar Nedumaran, Wen Sin Chong, Kok Seng Foo

Patent number: 9863696Abstract: Embodiments of the present invention provide a process for liquefaction of a natural gas. The process includes cooling the natural gas with a first refrigerant provided by a first cooling system and cooling the natural gas with a second refrigerant provided by a second cooling system. The second cooling system is a single phase cooling system. The first and second cooling systems operate independently from each other. The second refrigerant is cooled with the first refrigerant so that the cooling capacity of the second refrigerant and the second cooling system is increased.Type: GrantFiled: June 6, 2012Date of Patent: January 9, 2018Assignee: KEPPEL OFFSHORE & MARINE TECHNOLOGY CENTRE PTE LTDInventors: Wen Sin Chong, Xiaoxia Sheng, Ravindu Atapattu, Kok Seng Foo

Patent number: 9004102Abstract: Disclosed are various apparatus and method for transferring a hydrocarbon fluid between two bodies. To this purpose, a transfer skid and transfer hoses are moved from a first body to a second body to be installed thereupon to provide fluid communication between the two bodies. Offloading of hydrocarbon fluid may then take place between the two bodies. Emergency release operation may be triggered during the offloading, where the transfer hoses are disconnected from the transfer skid, and are returned to the first body. Various features of the transfer skid and associated apparatus allow the transfer skid to be installed on the second body with improved mating connections, transfer hoses to be returned to the first body after offloading operation without hydrocarbon fluid leakage, and transfer hoses to disconnect with speed and safety during emergency release operation.Type: GrantFiled: September 19, 2011Date of Patent: April 14, 2015Assignee: Keppel Offshore & Marine Technology Centre Pte LtdInventors: Kok Seng Foo, Asbjørn Mortensen, Alex Kah Keong Tan, Toh Tung Wong, Wen Sin Chong, Teng Kiat Lim

Patent number: 8864420Abstract: Disclosed are systems and methods for limiting structural damage to an affected offshore platform and preventing damage spread from the affected offshore platform to another platform during an accident or an emergency condition. An offshore platform arrangement includes a mobile offshore production unit (MOPU), a mobile storage platform and a mobile offloading platform which are disposed at a clearance distance from one another. The platforms are fluidly connected by pipes to allow hydrocarbon fluid transfer therebetween. The pipes are adapted to cease fluid communication of hydrocarbon fluid between platforms for preventing damage spread therebetween. Also disclosed is an offloading system for hydrocarbon fluid transfer which includes a lifting system having an extendable lifting arm and a spreader frame platform rotatably coupled to the lifting arm. The spreader frame platform is operable to support a transfer skid and allow angular adjustment of the transfer skid in a horizontal plane.Type: GrantFiled: February 28, 2012Date of Patent: October 21, 2014Assignee: Keppel Offshore & Marine Technology Centre Pte LtdInventors: Kok Seng Foo, Wen Sin Chong, Alex Kah Keong Tan, Xiao Xia Sheng, Asbjørn Mortensen
