Summary of the invention
The purpose of this utility model with the shortcoming overcoming prior art, a kind of inland river type liquified natural gas carrier (LNGC) that a kind of shallow draft, moldeed depth are low, maneuverability handling is good, LNG storage is safe is provided.
A kind of inland river of the present utility model type liquified natural gas carrier (LNGC), it comprises hull, the continuous main deck of individual layer is provided with in described hull, ship panel and cabin is respectively equipped with at ship stern, compass deck is provided with in the ship storehouse of ship panel tip position, ship stern is provided with basic propulsion system, described basic propulsion system comprises two hybrid fuel main frames, each described hybrid fuel main frame is connected with a set of rudder oar device respectively by gear case, the screw propeller of every suit rudder oar device adopts adjustable pitch propeller, stem is provided with bow thruster, two mutually isolated liquefaction cargo holds are provided with in described hull, an ears shape C type liquid goods tank is placed with respectively in described two liquefaction cargo holds, cargo hold material adopts the steel matter adapting to-164 DEG C of low temperature, two ears shape C type liquid goods tanks are connected respectively by the fuel inlet of pipeline with hybrid fuel main frame, an air chamber is communicated with respectively at the top of each liquefaction cargo hold, monitoring and protecting system for monitoring liquefaction cargo hold running state is installed in each liquefaction cargo hold, described compass deck is provided with collapsible mast radar installation.
The advantage that the utility model has and good effect are: adapt to river and mountain inland river and be greater than 4 meters of depth of water navigation channel traffic conditions, there is shallow draft, moldeed depth be low, maneuverability handling is good, LNG storage safety feature, ensure that the feature of Stability of Ship more than needed, Hull Strength, manoeuvring safety in course line, inland river; Inland river type liquified natural gas carrier (LNGC) selects C type cargo hold pressure resistant type good, and this cargo hold form type selecting is safe and reliable, and cargo tank thermal insulating is effective, and the goods holding time is long; Basic propulsion system uses liquid goods natural fuels boil-off gas as main fuel, realizes good economical and energy saving benefit and discharge-ring guaranteed request.
The utility model considered China inland river operating enviroment, meet IGC international norm, with relevant criterion and the specification of classification society, on the shipping safety basis ensureing liquefied natural gas, possesses the configuration of efficient boats and ships, achieve technical security reliability, safeguard convenience, the aspect abilities such as economy, the ship craft integrated performance of largest optimization.
Accompanying drawing explanation
Fig. 1 is the lateral plan of a kind of inland river of the present utility model type liquified natural gas carrier (LNGC);
Fig. 2 is the drawing in side sectional elevation of the carrier shown in Fig. 1.
Detailed description of the invention
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Consult Fig. 1-Fig. 2, a kind of inland river of the present utility model type liquified natural gas carrier (LNGC), it comprises hull, the continuous main deck 7 of individual layer is provided with in described hull, ship panel and cabin is respectively equipped with at ship stern, compass deck 8 is provided with in the ship storehouse of ship panel tip position, ship stern is provided with basic propulsion system, described basic propulsion system comprises two hybrid fuel main frames 2 (diesel oil+natural fuels), each described hybrid fuel main frame 2 is connected with a set of rudder oar device 4 respectively by gear case 3, the screw propeller of every suit rudder oar device 4 adopts adjustable pitch propeller, to ensure actv. propulsion of ship efficiency.For ease of the operation of i/o terminal, stem is provided with bow thruster 5, two mutually isolated liquefaction cargo holds are provided with in described hull, an ears shape C type liquid goods tank 1 is placed with respectively in described two liquefaction cargo holds, cargo hold material adopts the steel matter adapting to-164 DEG C of low temperature, preferably can adopt 9%Ni steel matter, two ears shape C type liquid goods tanks 1 are connected respectively by the fuel inlet of pipeline with hybrid fuel main frame 2, and the boil-off gas that the liquefied natural gas in liquid goods tank 1 is produced provides main fuel for basic propulsion system.Two cover fuel system can carry out any switching laws, to ensure the reliable redundancy that marine fuel uses, term of voyage basic propulsion system uses liquefied natural gas goods boil-off gas as fuel, relative marine diesel oil saves fuel cost, and the pollutants of gas emission reduces the requirement reaching energy-conserving and environment-protective simultaneously.An air chamber is communicated with respectively at the top of each liquefaction cargo hold; air chamber is that liquefaction cargo hold top is for collecting the cabin of natural gas vaporization gas; monitoring and protecting system for monitoring liquefaction cargo hold running state being installed in each liquefaction cargo hold, ensureing cargo storage safety requirements.Monitoring and protecting system can comprise temperature sensor, level sensor etc.Described compass deck 8 is provided with collapsible mast radar installation 6, can smoothly by the bridge of clear height on river and mountain less than 22 meters under making ship in ballast situation.
