Description
Technical field
The present invention relates to the workboat group that a kind of offshore natural gas liquefaction-accumulating-regasifies.
Background technology
Offshore drilling and the development of production technology make it that the different zones that petroleum industry has been had the ability in the world are given birth to
Production, the increasing natural gas produced with oil product are produced, due to associated gas small scale, the yield not
Greatly, do not reach and build submarine transport oil pipeline or establish the economic requirement that offshore installation realizes liquefied natural gas, without economic and reliable yet
Recovery technology so that associated gas after gas-liquid separation using torch burn-up mode remove, both pollute environment, waste again
Natural gas energy resource.The world has many regions to have substantial amounts of gas field to wait to exploit at present, but the high liquefaction of natural gas and cost of transportation
Also the bottleneck for constraining its exploitation and using has been turned into.Therefore, the recovery for retail natural gas is badly in need of in the production of offshore oil and gas
Technology and corresponding equipment.
The content of the invention
It is an object of the invention to provide the workboat group that a kind of offshore natural gas liquefaction-accumulating-regasifies, realize to sea
Oil field retail natural gas and the production operation in small-sized marginal gas field.
The present invention technical solution be：The workboat group of function is regasified with natural gas liquefaction accumulating, by pushing boat,
Natural gas liquefaction platform/ship, LNG Storage, Transport platform/ship and lng regas platform/ship are formed, its feature
It is：Described natural gas liquefaction platform/ship is made up of barge and natural gas liquefaction device；Described liquefied natural gas storage
Transporting platform/ship is made up of barge and liquefied natural gas storage compartment；Described lng regas platform/ship is by refuting
Ship and liquefied natural gas (LNG) regasification facilities are formed.
Described pushing boat is by double dynamical ship of the combustion oil and gas as fuel, can be respectively that natural gas liquefaction is put down
Platform/ship, liquefied natural gas transport platform/ship and lng regas platform/ship provide transportation power.
The present invention solves problem marine small-sized marginal gas field and that offshore oil production associated gas can not produce, is it
Production provides reliable producing equipment, has larger economic benefit and huge social benefit, cost is low, high efficiency, ring
Protect.

Schematic diagram.
In figure:1st, push boat, 2, natural gas liquefaction platform/ship, 3, LNG Storage, Transport platform/ship, 4, liquefied natural gas
Regasify platform/ship.
Embodiment
Illustrate embodiment below in conjunction with the accompanying drawings：
The actual conditions reasonable disposition produced according to offshore natural gas pushes boat 1, natural gas liquefaction platform/ship 2, liquefaction naturally
The quantity of gas accumulating platform/ship 3 and lng regas platform/ship 4.Push boat 1 and natural gas liquefaction platform/ship 2, liquefaction
Natural gas accumulating platform/ship 3, lng regas platform/ship 4 and LNG Storage, Transport platform/ship 3 and natural gas
Using mechanical-hydraulic connection, cryogenic hose connection and cable between liquefaction skid/ship 2, lng regas platform/ship 4
The key technologies such as snap joint, its mutual different connection in series-parallel assembled scheme is realized, realizes different processing functions.
1 is pushed boat using a kind of double fuel ship, including：Main hull, the cabin inside main hull and in cabin
Main frame, the superiors of main hull are provided with main deck, superstructure is provided with above main deck, in the top of cabin
The assembly of engine room casing and chimney is provided with, the main frame is using combustion oil and gas as fuel, and natural gas reservoir is in LNG
In storage tank, LNG storage tanks are arranged on main deck and positioned at the one or both sides of engine room casing and the assembly of chimney.
LNG Storage, Transport platform/ship 3 uses a kind of small-sized LNG barges, and the barge possesses c-type storage compartment or other types
The storage compartment of formula.
Natural gas liquefaction platform/ship 2, lng regas platform/ship 4 include hull part, natural gas collects system
System, selexol process decarburization dewatering system, liquefaction system, flash gas compression machine system, waste-gas burning system, refrigerant supplement system
System, heat medium system, holding vessel, loading dock.Regas system is will to be reused after the natural gas gasifying after liquefaction；Waste gas burning system
System is mainly burnt the fuel gas for producing, leaking in each system.Using each function treatment system in the prior art
Mature technology, the gas liquefaction processing requirement to natural gas can be achieved.
Different ships or platform/ship can have multiple combinations form to handle full industrial chain to reach service offshore natural gas
Demand.
