Description
The present invention relates to a floating mooring device and a method for unloading liquefied natural gas using the same.
Natural gas may be transported in gaseous form through onshore or offshore piping, or stored in LNG carriers in the form of liquefied natural gas (LNG) and delivered to consumers. Liquefied natural gas is obtained by liquefying natural gas to about -163 ℃, the volume is reduced to about 1/600 than in the gaseous state is suitable for long distance transport over the sea.
Recently, LNG RV (Regasification Vessel), which is loaded with LNG, is operated by sea, arrives at land demand, regasifies stored liquefied natural gas, and is unloaded as natural gas. The LNG RV may be equipped with devices such as a storage tank for storing liquefied natural gas and a regasification plant for regasifying the liquefied natural gas.
In addition, demand for floating structures such as LNG Floating, Production, Storage and Offloading (FPSO) or LNG Floating Storage and Regasification Unit (FSRU) is increasing. In such a floating structure, a storage tank for storing liquefied natural gas is installed, and devices for liquefying natural gas or regasifying liquefied natural gas may be mounted as necessary. In detail, the LNG FPSO is a floating structure that liquefies the natural gas extracted from the gas well directly in the sea and stores it in the storage tank, and transfers the liquefied natural gas stored in the storage tank to the LNG carrier if necessary. LNG FSRU is a floating offshore structure that stores liquefied natural gas unloaded from LNG carriers in a storage tank at seas far from the land, and then regasifies the liquefied natural gas as needed to supply it to the demand.
As such, floating offshore structures such as LNG FPSO and LNG FSRU, which store liquid cargo such as LNG, generally have the form of a barge used while being moored by a single point mooring system such as a turret.
In addition, the floating structure may be moored with the LNG carrier to carry the liquefied natural gas stored in the storage tank of the floating structure to the LNG carrier.
However, the above conventional technology has the following problems.
In order for the floating structure to safely moore with the LNG carrier, the floating structure must be formed longer than the LNG carrier. In other words, the LNG Carrier may be formed of a smaller length than the floating structure to moor. That is, there is a problem in that the size of the LNG carrier that can be used for a particular floating structure is limited.
In particular, when an LNG carrier is used at the same time as a cargo ship using a moss type cargo hold and a cargo ship using a membrane type cargo hold, a floating structure is provided to compensate for the difference in the position of the manifold. There is a problem that it must be formed long.
