摘要： A subsea fluid storage system comprises: a seabed foundation; a tensile member such as a pipe or a wire extending upwardly from the foundation; and a subsea buoy applying buoyant upthrust to support the tensile member in an upright orientation. At least one fluid storage container is disposed between the foundation and the buoy. The or each container may be disposed around the tensile member, for example with the tensile member extending through the container. The container has at least one inlet or outlet for fluid communication with a source or a consumer of fluid to be stored in the container.

摘要： An underwater storage tank having a flexible multilayer tank containing a working liquid is provided. The flexible multilayer tank has at least one internal electrical insulating layer in contact with the working fluid, at least one external electrical insulating layer in contact with sea water, and at least one intermediate electric conductive layer sealed between the at least one internal electrical insulating layer and the at least one external electrical insulating layer. At least one first electrical connection means is connected to the at least one intermediate electric conductive layer, the least one first electrical connection means being electrically connectable to an electrical grounded measurement instrument to assess physical integrity of the flexible multilayer tank.

摘要： A high-performance seafloor flexible oil storage system, solving the existing problems of high storage cost and difficult maintenance of crude oil in offshore oilfields, comprises, sequentially connected, an oil-water separator, a pressure pump, and an input riser extending downward below the sealevel; and a pipeline and multiple flexible oil storage tanks having the same structure with each communicated therewith through a control valve are arranged below the sealevel. One end of the pipeline is communicated with the input riser through a blocking valve and an input valve, and the other end further sequentially connected with an outlet booster pump, an output valve, and an output riser extending upwards above the sealevel and connected to a tanker through a cooler and an output pump. The flexible oil storage tank has a concrete counterweight connected thereunder for fixing it to a seabed. The system has simple structure, convenient maintenance and good practicability.

摘要： A subsea storage unit includes a pressure hull having a cargo hold configured for storing cargo. The pressure hull has a movable hatch, providing access to the cargo hold; and a base configured for supporting the storage unit on a seabed. The unit also includes a suspension, whereby the storage unit can be lifted and lowered in a body of water, and a ballast. A seabed facility can be configured for receiving and accommodating at least one subsea storage unit.

摘要： Techniques and systems to remove a portion of a drill floor from an offshore vessel. The drill floor may include an immovable section comprising a first portion of a surface area of the drill floor. The drill floor may also include a moveable section comprising a second portion of the surface area of the drill floor. Additionally, the drill floor may include an actuator configured to retract the moveable section from a first position to a second position to remove the second portion of the surface area of the drill floor.

摘要： An underwater energy storage system includes a tank for storing a compressed gas that is adapted to be stored underwater. The tank includes at least one water opening through which water from surrounding environment can flow into and out of the tank, and at least one gas opening through which the compressed gas is received. The underwater energy storage system further includes at least one duct communicating between the at least one opening for gas flow and a source of compressed gas and a compartment constructed over a roof of the tank, wherein said compartment is adapted for receiving weights at a sinking site of the tank.

摘要： A subsea fluids storage facility comprises a tank for holding and separating fluids which is equipped with ballast capacity and a separable base to be deployed upon the seabed in shallow or deep water, and the storage facility is connectable to a surface production facility, especially a buoy for processing fluids. In deep water the tank is held at a depth above the base for temperature controlled stabilization of produced oil in the tank.

摘要： A subsea oil over water storage tank, having one or multiple of high dynamic range, gas-liquid separators, which first receive oil well fluids, and cyclically depressurize and release free and solution gas to surface, and then expel unseparated liquids to the subsea storage tank, where the oil and water may be further separated by gravity separation, providing a means of separating stabilising crude oil.
