Description

[0001] APPARATUS AND METHOD FOR SUPPLYING ELECTRIC POWER USING MARINE RESOURCES [0002]

The present invention relates to a power supply apparatus and method using marine resources, and more particularly, to a power supply apparatus and method for generating electricity using oil and gas drilled in the ocean and supplying the power to a land or sea power consumer using a storage battery line And methods.

As the international phenomenon of industrialization and industry develops, the use of resources such as petroleum is gradually increasing, and thus the stable production and supply of oil is becoming a very important issue on a global scale.

For this reason, the development of the deep-sea oil field, which has been neglected since nowadays due to its inefficiency, has become economical. Therefore, along with the development of seabed mining technology, drilling rigs with drilling facilities suitable for the development of such oilfields have been developed. Crude oil and gas produced in the ocean are typically transported overland to the land.

1 is a view showing an example of a natural gas supply method according to the prior art. Referring to FIG. 1, the natural gas is produced in the marine plant 110 and is transported to the land via the pipe 120. The natural gas is liquefied in the liquefaction facility 130 on the land and stored in the storage tank 140. Liquefied natural gas (LNG) is obtained by cooling natural gas to -163 ° C. It is very suitable for long distance transportation through the sea because the volume is reduced to approximately 1/600 of that of natural gas. The liquefied natural gas stored in the storage tank 140 is transported to the destination by the LNG carrier 150. [

2 is a view showing another example of a natural gas supply method according to the prior art. 2, the natural gas is produced in the production facility 211 of the floating production storage and offloading (FPSO) 210, the natural gas is liquefied in the liquefaction facility 212, (213). The LNG stored in the storage facility 213 is transported to the destination through the LNG carrier 220.

The LNG transported by the LNG carriers 150 and 220 is regenerated through the LNG floating storage and regasification unit (FSRU) or land terminal, and supplied to the consumer. Alternatively, if LNG is transported by an LNG regasification vessel, it is regenerated from the LNG regasification line and supplied directly to the consumer.

According to the prior art shown in FIGS. 1 and 2, additional processes such as a liquefaction and regeneration process of natural gas and a process for removing impurities of natural gas for liquefaction are required. Since the LNG carriers 150 and 220 are thermally insulated, external heat is continuously transferred to the LNG carriers 150 and 220 because the LNG carriers are evaporated even at a high temperature of -163 ° C. at normal pressure. There is a problem that LNG is continuously vaporized in the cargo hold and boil-off gas is generated in the cargo hold. In particular, the prior art shown in FIG. 1 has a problem in that additional facilities such as land equipment and piping for transporting natural gas to land are required.
