Facilities for offshore liquefied natural gas floating storage with jack-up platform regasification unit
Facilities for offshore liquefied natural gas (LNG) floating storage with jack-up platform regasification unit, the facilities including: a jack-up unit comprising legs which have bottom part to be fixable to a sea bed and top part to be exposed to a surface of water, and a hull to be movable up and down with respect to the legs; a storage unit moored at the jack-up unit providing a space for storing LNG; a regasification unit as a module which regasifies the LNG supplied from the storage unit, installed on a top portion of the jack-up unit, separable from the jack-up unit; a utility unit comprising a power source and a sea water pump to supply power and sea water to the regasification unit; and a piping unit comprising unloading pipe for connecting the regasification unit and the storage unit and supplying pipe for carrying natural gas gasified by the regasification unit.
1. Facilities for offshore liquefied natural gas (LNG) floating storage with a jack-up platform regasification unit, the facilities comprising:
a jack-up unit comprising legs which have a bottom part to be fixable to a sea bed and a top part to be exposed to a surface of water, and a hull to be movable up and down with respect to the legs;
a storage unit moored at the jack-up unit providing a space for storing LNG;
a regasification unit as a module which regasifies the LNG supplied from the storage unit, installed on a top portion of the jack-up unit, is separable from the jack-up unit;
a utility unit comprising a power source and a sea water pump to supply power and sea water to the regasification unit; and
a piping unit comprising unloading pipe for connecting the regasification unit and the storage unit and supplying pipe for carrying natural gas gasified by the regasification unit,
wherein the utility unit is implemented as a module to be separable from the jack-up unit.
2. The facilities of claim 1 , wherein the regasification unit uses an open rack vaporizer (ORV) using sea water for heat exchanger.
3. The facilities of claim 2 , wherein the sea water pump and a ballast water pump disposed in the storage unit are simultaneously used to supply sea water to the regasification unit.
4. The facilities of claim 1 , wherein a power facility, a steam generator, and a ballast water pump disposed in the storage unit are used to supply power, steam, and sea water, respectively, which are necessary for the regasification unit.
5. The facilities of claim 1 , wherein the storage unit is the LNG carrier or a floating storage unit (FSU).
6. Facilities for offshore liquefied natural gas (LNG) floating storage with a jack-up platform regasification unit, the facilities comprising:
a jack-up unit comprising legs which have a bottom part to be fixable to a sea bed and a top part to be exposed to a surface of water, and a hull to be movable up and down with respect to the legs;
a storage unit moored at the jack-up unit providing a space for storing LNG;
a regasification unit as a module which regasifies the LNG supplied from the storage unit, installed on a top portion of the jack-up unit, is separable from the jack-up unit;
a utility unit comprising a power source and a sea water pump to supply power an sea water to the regasification unit; and
a piping unit comprising unloading pipe for connecting the regasification unit and the storage unit and supplying pipe for carrying natural gas gasified by the regasification unit,
wherein the storage unit is fixed to the jack-up unit and carries the LNG to the regasification unit.
