  • Patent number: 9302746
    Abstract: During an offloading operation between a first and a second body, an operating envelope of an offloading system can be displaced to compensate for a drifting movement of one of the bodies. By appropriately displacing the operating envelope, offloading operation can continue under safe conditions even though the working limit of the original operating envelope is breached due to the drifting movement of one of the bodies.

  • Patent number: 9004102
    Abstract: 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.

  • Patent number: 9004103
    Abstract: Disclosed are various apparatus and method for transferring a hydrocarbon fluid between two bodies. An offloading system for facilitating hydrocarbon fluid transfer between two bodies includes a transfer skid and a lifting system. The transfer skid is movable from a first body to a second body to be installed thereupon to facilitate hydrocarbon fluid transfer to and from the first and the second bodies. The lifting system may be provided on the first body, and includes an extendable lifting arm; a spreader frame attachment which includes at least a first and a second lifting device to support the transfer skid, wherein the spreader frame attachment is rotatably coupled to the extendable lifting arm to allow angular or rotatable adjustment of the transfer skid in a horizontal plane.

  • Patent number: 8864420
    Abstract: 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.
