Abstract: A cargo transfer monitoring system at least comprises at least one vessel motion sensor, one pair of wireless modems, a central data processing unit with decision-making module, a rugged display panel as the operator station, and communication coupling. The cargo transfer operation will be carried out by a crane operator sitting in the crane cabin on the primary vessel. The transfer will take place either from target vessel to primary vessel or from primary vessel to target vessel. The sensor(s) collect the real-time motion of vessels, which is carried over to the central computer through data cable or wireless radio link. The decision-making module predicts the motion of the vessels for a subsequent time period. Based on the predicted value, the decision-making module projects the expected or predicted impact force on the payload if the operation is started at the particular time.

Abstract: This invention relates to a vessel having an extendable and retractable cursor frame assembly for deploying other vessels into a body of water. The retractable cursor frame assembly on the main vessel may be retracted and secured on a module of the main vessel as the main vessel is in transit. When another vessel is to be deployed into the body of water from the main vessel, the cursor frame assembly is then extended into the body of water to facilitate the launch of the other vessel.

Abstract: A rapid transition floating vessel that is able to follow the yaw motions of a turret moored floating vessel is provided. The rapid transition floating vessel includes a system and processes for dynamically positioning the floating vessel alongside a turret moored floating vessel whereby the floating vessel remains at a safe distance while being connected to the turret moored floating vessel. This is achieved by the floating vessel following the yaw motions of the turret moored floating vessel as the turret moored floating vessel weathervanes about a center of the turret moorings.

Abstract: This invention relates to an integrated heavy lift and logistics vessel for receiving another vessel. Further the integrated heavy lift and logistics vessel is able to provide logistical support to the other vessel in remote locations. More particularly, this invention relates to an integrated heavy lift and logistics vessel that is designed to carry out heavy lifting and logistic supply functions in a stable manner. The integrated heavy lift and logistics vessel is also equipped with safe refuge quarters, helipad(s), various forms of storage, and areas for storage.

Abstract: A jackup deployed riser protection structure comprises a plurality of coupler receivers disposed onto a jackup hull, a tubular sleeve, wherein the tubular sleeve is a hollow structure that allows a riser to pass through, a support structure coupled with the tubular sleeve to provide support for the tubular sleeve, and a plurality of couplers coupled with the support structure, wherein each of the plurality of couplers is coupled with one of the plurality of coupler receivers, so that the jackup deployed riser protection structure is supported by the jackup hull in order to provide protection to the riser.

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.

Abstract: The present invention relates to a coupling system for coupling two floating structures together. The coupling system is able to accommodate the relative rotational and translation motions between the two floating structures without becoming disconnected. Furthermore, the coupling system has an engagement and disengagement mechanism that may be implemented remotely and efficiently.

Abstract: 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.
