Dress method.
Background technology
Drug on the market in current bulk freighter market, and Baltic Sea index is only 3% during peak, and bulk freighter is big
Amount is idle, and the bulk freighter of operation is in serious lossing state.Market compressed natural gas ship famine,
Needed for new design-build compressed natural gas ship, cost is high, and the cycle is long, and without clear and definite specification.Use existing bulk goods
Ship's alternation, increases compressed natural gas tank bin so that it is meet the requirement of transport compressed natural gas in cargo hold,
Make full use of existing resource, it is achieved the purpose of cost efficiency.
Summary of the invention
For the demand of prior art, it is an object of the invention to provide a kind of vessel for transport of compressed natural gas and
Method of modifying, is reequiped by the bulk freighter left unused market between 50,000 tons to 10 tons, reaches transport pressure
The purpose of contracting natural gas.
The present invention provides a kind of vessel for transport of compressed natural gas, including: bulk freighter, compressed natural gas tank, pressure
Contracting natural gas tank bin, support platform, bottom foot base and inspection passage；Wherein,
Described compressed natural gas tank is integrally disposed in described compressed natural gas tank bin；
Being provided with multiple cargo hold in described bulk freighter, the both sides hypotenuse of described cargo hold inner bottom part is provided with described support
Platform, the height of described support platform and width are not less than the size of compressed natural gas tank bin described in surrounding；
Described bottom foot base is arranged on the base plate that the upper surface of described support platform is smooth with described cargo hold inner bottom part
On, pile up the described compressed natural gas tank bin of multilamellar in described bottom foot base；
Described inspection passage is arranged on around the bulkhead of described cargo compartment.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described compressed natural gas tank is steel inner container, and outer layer carbon fiber wraps up.
Further, on described bulk freighter, vacant position is additionally provided with gas compressor.
Further, the cabin of described bulk freighter or the upper vacant position of described cargo hold are additionally provided with noble gas
Generator, arranges structure air channel in described cargo hold surrounding.
Further, it is also arranged above hazardous gas bleeder pipe and pressure valve at described cargo hold.
Bulk freighter for realizing would sit idle for repacks the vessel for transport of compressed natural gas of the above present invention, institute into
State method of modifying to include:
A. by integrated for described compressed natural gas tank, composition compressed natural gas tank case is protected by frame structure
Cabinet；
B. the both sides hypotenuse at described cargo hold inner bottom part arranges support platform；
C. it is set on the upper surface of the described support platform base plate smooth with described cargo hold inner bottom part the described end
Runners；
D. described compressed natural gas tank bin is piled up multilamellar and to fix in described cargo hold, horizontal bin it
Between headspace, undermost described compressed natural gas tank bin is fixed in described bottom foot base；
E. every layer of described compressed natural gas tank is connected by pipeline, then the pipeline of every layer is aggregated into house steward
Road.
F. arranging inspection passage at described cargo hold, side is fixed on the bulkhead of described cargo hold, and opposite side is solid

On the basis of above-mentioned repacking step, the present invention can also do following improvement.
Further, inert gas generator is aboard ship set.
Further, hazardous gas bleeder pipe and pressure valve are aboard ship set.
Further, gas compressor is aboard ship set.
The invention has the beneficial effects as follows: utilize the most idle or reequiped by abandoning bulk freighter, promoting bulk goods
Ship is worth, and the bulk freighter recondition expense between 50,000 tons to 10 tons is low, and space availability ratio is high, comes into operation
Hurry up.If directly according to the collection shipment that movement requirement design-build is special, the cycle is long, costly, and mesh
Before do not have maturation vessel for transport of compressed natural gas for reference, with bulk freighter repacking experience for specialize in later
The boats and ships of design compressed natural gas transport provide reference value.
Current bulk freighter freight charges are cheap, be difficult to take on a new look, repack compression in being in lossing state, and 5 years
After natural gas carrier vessel, can making a profit instead of suffering a loss of bulk freighter, freight rate improves more than 2 times, 5 years or 10 years
After rear bulk freighter freight rate is greatly improved, compressed natural gas tank entities can be taken out, on cabin inner bottom plating
Bin bottom foot base and bracing frame cut off, recover bulk freighter original appearance, again transport bulk goods.The pressure removed
Contracting natural gas tank bin is for carrier or for being placed in the special purpose ship of transport compressed natural gas.
Land or offshore oil production well all can produce accompanying gas, these gas volume productions in oil recovery process at present
Measure little, if construction natural gas line or gas liquefaction treating stations cost are the highest.It is difficult to cost-recovering,
Current way accompanying gas all burns (being commonly called as a sky lamp), and the natural gas carrier vessel after repacking can
To reclaim the gas that this part slatterns, make full use of resource, protect environment, benefit the society.
