Description
Technical Field
The utility model relates to a boats and ships and ocean engineering field particularly, in particular to deep water floating platform pilot test ballast water system.
Background
Floating platforms operating at sea require a complete ballast water system to ensure good buoyancy. With the increasing reduction of offshore oil and gas resources and the increasing of the total cost of oil and gas field development, the requirement for the development of novel deepwater ocean platforms is continuously increased. Chinese patent CN103912245A and US9327805B2 jointly propose a novel deep water drilling production vertical oil storage platform, which adopts the oil-water replacement technology to store the crude oil produced by the Spar platform in an oil storage cabin of which the platform main body is positioned below the water surface, thereby greatly reducing the deep sea oil and gas exploitation cost.
The oil-water replacement technology is also called as wet oil storage technology, and the technology is widely used for gravity concrete oil storage platforms and seabed oil storage tanks by foreign oil companies. The principle of the oil-water replacement oil storage technology is as follows: the oil is not miscible with water and the density of the oil is lower than that of water; during oil storage, crude oil is injected into an oil storage cabin from the top of the cabin at a low speed, oil can float on water, seawater with the same volume is discharged out of the cabin from the bottom of the cabin, and meanwhile, oil and water can spontaneously form an oil-water interface in the cabin; during oil unloading, crude oil is extracted from the top of the tank at a high speed, and seawater at the bottom of the tank is communicated with external seawater, enters the oil storage tank from the bottom of the tank under the action of hydrostatic pressure and fills a crude oil space. In the process of oil storage and unloading, the oil-water interface moves up and down, and the relative volume of the crude oil and the seawater in the oil storage tank is continuously adjusted, so that the oil storage tank is always kept in a liquid-full state. Because the wet-type oil storage tank is filled with oil and water all the time and is positioned below the water surface, the wet-type oil storage tank is less influenced by wind waves, sea currents, ice and the like, the structure bears less load, and the required tank capacity and ballast amount are less, so that compared with the traditional dry-type oil storage technology, the oil storage cost of the oil-water replacement technology is lower, the oil storage safety is higher, and the advantages are very obvious.
The research and development of the novel deepwater ocean platform need to be verified by a large number of model tests. The development of a novel deepwater ocean platform needs to step over a technology maturity step, wherein the technology maturity of a small test can reach 4-5 levels. According to the standard (TRL) of the development readiness of the international new technology, a high-simulation pilot test is required to ensure that the technical readiness reaches 7 grades, so that the new technology is put to industrial application. The ballast water system of the new platform and its control method must be considered in pilot trials.
At present, most of floating platform tests are carried out indoors by adopting small-scale non-steel material models, and a pilot test with complete outdoor environment systems made of large-scale steel materials is not mentioned, so that the ballast water system suitable for the pilot test and the control method thereof are not mentioned.
The design of the ballast water system for the floating platform pilot test needs to consider the technical requirements of the novel platform and the cost and feasibility of the pilot test. For the novel vertical oil storage platform for deep water drilling production, which is proposed by the Chinese patent CN103912245A and the U.S. patent US9327805B2, in the oil storage process, the same volume of crude oil replaces the same volume of seawater out of the oil storage tank, the load of the platform is reduced, in the oil discharge process, the same volume of seawater replaces the same volume of crude oil out of the oil storage tank, and the load of the platform is increased. Accordingly, the draft of the platform will vary. In order to ensure the smooth operation of the pilot test, a set of ballast water system which keeps the draft of the novel floating ocean platform unchanged needs to be designed.
