Abstract: A drag-reducing separator plate for a moonpool, wherein the upper part thereof is a straight wall perpendicular to the sea level, the lower part thereof is connected to a baffle, and a connecting portion is connected between the straight wall and the baffle. The connecting portion may be in the shape of an arc. The shape of the drag-reducing separator plate matches that of the rear wall of the moonpool. During navigation, the drag-reducing separator plate is located in the middle or front of the moonpool, and can cooperate with a drag-reducing notch on the rear wall of the moonpool to greatly reduce the drag induced by intense sloshing of water in the moonpool during navigation of an offshore vessel. When offshore operations are performed under a station keeping condition, the drag-reducing separator plate is moved to the rear wall of the moonpool to avoid hindering the offshore operations.

Abstract: A nonmetallic flexible pipe and a manufacturing method thereof. The nonmetallic flexible pipe comprises, from the inside to the outside, an inner liner, a pressure bearing layer, an isolation layer, a tensile layer, a functional layer, and a protective layer, wherein two adjacent layers are non-rigidly bonded. The inner liner layer is made from a thermoplastic polymer. The pressure bearing layer is made from a fiber-reinforced resin-based composite material. The isolation layer is made from a thermoplastic polymer. The tensile layer is made from a resin-reinforced fiber material. At least one of an optical fiber, a cable, a tracing ribbon, a pipe for conveying a heat transfer medium, a pressure sensor, and a temperature sensor is provided in the functional layer. The protective layer is made from a thermoplastic polymer.

Abstract: A floating dockable liquefied natural gas supply station, comprising: a main hull, a bottom base and a positioning system. The bottom base comprises a base plate or at least two base plates. The base plate is securely connected to a lower lateral side of the main hull by means of a splicing securing system. Therefore, the main hull and the bottom base of the floating dockable liquefied natural gas supply station can be assembled in a modular manner. It is possible to individually construct the main hull and bottom base of the floating dockable liquefied natural gas supply station, and to then use a modular method for connecting and assembling same on the ocean or on land, thus being able to flexibly form various types and dimensions of supply station, allowing for docking transport vessels accommodating various loading capacities of liquefied natural gas (LNG), and reducing the construction cost thereof.

Abstract: A floating drilling platform for offshore oil/gas drilling and exploration in ice-infested polar areas comprises a deck module, a hard compartment, and a soft compartment sequentially connected from top to bottom. The bottom of the deck module is connected to the top of the hard compartment by evenly distributed column. Both the hard and the soft compartments are cylinders centrally arranged with center wells. The deck module is also centrally arranged with a center well. The hard compartment, the soft compartment and the deck module are coincident with a centerline. The outer diameter of the soft compartment, as well as that of the deck module, is larger than that of the hard compartment. The top of the hard compartment is designed with a circular inclined plane upwardly and outwardly arranged at the outer edge. The top of the circular inclined plane is connected to the bottom of the deck module.

Abstract: An offshore floating platform for operating in ice-infested waters and harsh environment for oil/gas drilling and exploration in Arctic area comprises four (4) sections, i.e., an upper cone, a transition section, a lower cone and a bottom frame. The upper cone, the transition section, the lower cone and the bottom frame are coincident with a centerline, and a through center well is designed around the centerline from top to bottom. The diameter at the bottom frame is smaller than that of the main body of the center well. The upper cone, the transition section and the lower cone are internally connected and divided into plural compartments. Through ballast compartments are designed outside the sidewall of the upper cone, the transition section and the lower cone vertically connected with a consistent cross-sectional area from top to bottom. Plural ballast compartments and void compartments are arranged within the bottom frame.
