Abstract
A kind of includes being realized than the natural gas liquefaction ship of the liquified natural gas carrier (LNGC) of the ship of suitable size (LNGC) bigger deadweight tonnage by reducing the density of cargo of LNGC.This difference provides space in the port side and starboard side of goods tank, to increase the size of adjacent wing tank.The goods tank size that the size increase of wing tank occupies ship reduces generated space, and can support larger upper trunk deck.Ballast wing tank and smaller goods tank increase available loading capacity.Using this scheme, the larger upper trunk deck of ship can support efficient floating liquefying plant, so as to improve LNG value chains, because it can produce 2.0 3.0MTPA in the floor space of the standard hull of such as Q Max hulls.
Description
Technical field
The embodiment of invention described herein is related to the ocean liquefaction field of natural gas.More specifically, but non-limiting
Ground, one or more embodiments of the invention describe natural gas liquefaction ship.
Background technology
Natural gas is transported from production site to consumption place typically via pipeline.However, a large amount of natural gas exists sometimes
Production is produced considerably beyond the area of demand or country, and may not by the position of natural gas transportation to business demand by pipeline
It is feasible, such as because production site and the position of demand are separated by ocean or rainforest.If without effective mode by natural gas
It is transported to the position of business demand, so that natural gas is made a market of may lose.
The liquefaction of natural gas is conducive to the storage and transport of natural gas.Liquefied natural gas (" LNG ") just corresponds to equivalent
The 1/600 of gaseous natural gas volume.LNG is by the way that natural gas is cooled to its boiling point or less (- 259 ℉ under atmospheric pressure) next life
Production.LNG can be stored in the slightly above low-temperature (low temperature) vessel of atmospheric pressure.By increasing the temperature of LNG, it can regasify and return to it
Gas form.
The demand promotion of natural gas by specialized ship transports LNG.It, can in the natural gas of the abundant area production of natural gas
It can be liquefied and transport the place for abroad reaching and needing most to by this method.In general, natural gas is adopted by one or more pipeline
Collect the liquefaction facility based on land (continental rise).Continental rise liquefaction facility and relevant acquisition pipeline are with high costs, may occupy big
Area soil and time several years is needed to secure permission and build.Therefore, continental rise liquefaction facility is not optimal adaptation natural gas supply
Change in location or the small-sized or idle gas reserves of liquefaction.In addition, once natural gas liquefies in land-based infrastructure, LNG must
It must be stored in large-scale continental rise low-temperature storage tank, terminal facilities are transported by special cryogenic piping, are then loaded into outfit
There is in the ship of low temperature chamber (such ship can be referred to as LNG cargo ships or " LNGC "), this combination may increase natural gas
Transport the overall expenses of its final destination.
Substantially LNG projects are costly.Liquefying plant is the largest cost structure, accounts about the total of LNG value chains
The 50% of cost；Therefore, the cost reduction of liquefying plant is a major issue.The capital cost of liquefying plant depends on several
The quality of factor, such as plant site selection, scale, field condition and unstripped gas.The thermodynamics development of liquefaction process is good.Therefore,
Improvement of the improvement of industry from liquefaction process and the infrastructure for reducing cost.Certainly, Life Cycle of the development cost in facility
Interim is all capitalization.Therefore, the efficiency of process and infrastructure may be decreased LNG per ton in liquefying plant life cycle
Totle drilling cost.
A kind of method for reducing liquefied natural gas cost is the liquid gas on floating unit or ship.Supplier is engineered
Existing LNGC is to house boat-carrying liquefaction device.However, the LNGC that can be used for being transformed usually is a lack of additional liquefaction device
The obsolete vessel in required space and loading capacity.On these older cargo ships, ship designer by convention can be original because of ship
Function, such as LNGC, and cargo tank sizes is made to maximize, therefore the cargo hold of hull consumes most boat-carrying weight.Deadweight tonnage
It is to weigh quality that shipping carries or can be with the weight of safe carriage：It does not include the weight of ship.The loading capacity of ship makes it
With most important, because if the equipment on ship is too heavy, then ship may be absorbed water too deep or is broken under excessive longitudinal stress.
It is added sometimes in the both sides of LNGC and stabilizes the wing to create more goods spaces and increase loading capacity, but usually this will not be provided
Liquefaction device of enough loading capacity to allow addition complicated.In addition, old tonnage LNGC ships generally use steam drive, can not produce
The power of 40-50MW needed for raw liquefaction device.Since these sizes and power limit, old tonnage ship needs to carry out expensive return
Work could be transform as natural gas liquefaction ship.In view of the cost for providing power for obsolete vessel, be used for a long time in LNGC (such as more than
5 years) in the case of it is such do over again it is especially economically impractical.
Although the existing new boatbuilding of LNGC planned designs can be used, due to the increase in demand of natural gas liquefaction, mostly
Number LNGC plans for the increase of heavy liquefaction device without providing necessary loading capacity.
From the above problem, it is apparent that current old tonnage ship is not suitable for transforming energy as due to above-mentioned many disadvantages
Enough liquefied LNGC, and it is designed to that the new boatbuilding for maximizing goods space does not have the loading capacity needed for liquefaction device.Therefore,
Need a kind of improved natural gas liquefaction ship.
