Maritime bottom-sitting type natural gas treatment device

Abstract

The invention belongs to the technical field of LNG production and particularly relates to a maritime bottom-sitting type natural gas treatment device. The maritime bottom-sitting type natural gas treatment device comprises a main hull and an underwater foundation, a natural gas treatment facility and a liquefied natural gas storage system are arranged on the main hull, multiple ballast tanks arearranged on the hull bottom and the periphery of the main hull, and the top face of the underwater foundation is used for bearing the main hull. Ballast water is injected in or drained out of the ballast tanks through ballast pumps so that the main hull can be adjusted to sink or float, and bottom-sitting installation of the device is achieved. A rubber cushion board can be arranged between a bottom board of the hull bottom of the main hull and the top face of the underwater foundation so as to increase the friction coefficient. The maritime bottom-sitting type natural gas treatment device hasthe beneficial effects that no mooring system needs to be arranged, under the effect of wind, waves and streams, a setting type bottom-sitting mode can guarantee that the device does not move at all,LNG stored on the device cannot shake, and continuity and safety of natural gas production and treatment are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of LNG production, and in particular relates to an offshore bottom-mounted natural gas processing device. Background technique [0002] The diversification of energy resources, increasing energy demand and environmental protection requirements have made the world's LNG supply and demand increasingly attractive. Now, the world LNG industry has formed a complete industrial chain from production, storage, shipment, to receiving and regasification. The current natural gas processing and LNG production installations are mainly divided into land installations and offshore floating installations. [0003] Onshore installations mainly include onshore LNG liquefaction plants and onshore LNG receiving stations. Land installations occupy a large area and are fixed facilities. The onshore device has ample space, unlimited production or processing capacity, less environmental impact, stable equipment operation, and lo...

AI Technical Summary

Problems solved by technology

However, under the action of wind, waves and currents, the above-mentioned floating devices will generally produce movements such as movement, rolling and pitching in all directions, and have high requirements for mooring systems. Common mooring systems include single-point mooring and winches. Mooring and spud mooring, etc. These mooring methods cannot guarantee that the device will not move at all

The movement of the floating device has adverse effects on the operation of the equipment, and the sloshing of the liquid in the LNG storage tank also constitutes a special safety problem. The loading and unloading operations of the floating device and the LNG ship are relatively risky.

In addition, the above-mentioned floating devices need to be shut down in harsh environments
