The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of Liquefied Natural Gas fuel filling ship, comprise hull and drive system, on described hull, be provided with main deck, in described hull, be provided with LNG liquid goods tank and LNG fuel storage cabin, described LNG liquid goods tank is arranged in described LNG fuel storage cabin; On described main deck, be provided with filling mooring back cushion, evaporator room, filling manifold and filling loop wheel machine, described filling manifold is fixed in described evaporator room, and described filling loop wheel machine is installed near stem, and described filling manifold is connected in described evaporator room.
Described LNG fuel storage cabin adopts the double-deck double hull configuration being formed by outer wall and inwall, be provided with and cut apart bulkhead in the both sides of described LNG liquid goods tank, described in cut apart bulkhead and be positioned at the inner side of described inwall.
Described main deck is provided with the bulge-structure with described LNG liquid goods tank adaptation.
Described drive system comprises the basic propulsion system that is arranged on ship stern and the thruster motion device that is arranged on stem, and described basic propulsion system adopts two full-rotating rudder paddles.
Be provided with collision bulkhead at described stem, described collision bulkhead is positioned at the front of described thruster motion device.
Advantage and the good effect that the utlity model has are: can realize a certain amount of LNG fuel of the carrying of low temperature liquid cargo containment system control and management, can be on the water (single user wharf, anchorage or in the same way between the parallel boats and ships of low-speed stable) carry out LNG fuel and/or fuel oil supply for the boats and ships taking LNG as power fuel, have the transportation function of LNG fuel in certain operation area simultaneously concurrently, can realize the flexible transhipment of peak regulation operation between LNG consumption terminal and similar relatively large LNG fuel medium-long range in bulk.Can promote the application of LNG fuel in maritime industry, expand clean energy resource overlay area, greatly reduce disposal of pollutants, environmental protection is had to positive effect.The power system of this ship, fuel system adopt modular design, subregion layout, cluster assembling, are convenient to mounting, commissioning and maintenance maintenance, and this ship can be realized operational security, yarage and the environment friendly of boats and ships simultaneously.The systems such as the LNG storage of this ship, supply, filling design for innovative form, and manoevreability is good, and filling efficiency is high, is applicable to polytype fuel receiving terminal, service waters broadness, has the huge market space.

Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1~Fig. 3, a kind of Liquefied Natural Gas fuel filling ship, comprises hull and drive system, is provided with main deck 3 on described hull, in described hull, be provided with LNG liquid goods tank 1 and LNG fuel storage cabin 2, described LNG liquid goods tank 1 is arranged in described LNG fuel storage cabin 2; On described main deck 3, be provided with filling mooring back cushion 4, evaporator room 5, filling manifold 6 and filling loop wheel machine 7, described filling manifold 6 is fixed in described evaporator room 5, described filling loop wheel machine 7 is installed near stem, and described filling manifold 6 is connected in described evaporator room 5.
In the present embodiment, described LNG fuel storage cabin 2 adopts the double-deck double hull configuration being formed by outer wall 9 and inwall 10, be provided with and cut apart bulkhead 11 in the both sides of described LNG liquid goods tank 1, described in cut apart bulkhead 11 and be positioned at the inner side of described inwall 10.Described main deck 3 is provided with the bulge-structure with described LNG liquid goods tank 1 adaptation.Described drive system comprises the basic propulsion system 14 that is arranged on ship stern and the thruster motion device 12 that is arranged on stem, and described basic propulsion system 14 adopts two full-rotating rudder paddles 13.Be provided with collision bulkhead 8 at described stem, described collision bulkhead 8 is positioned at the front of described thruster motion device 12.Main deck in cabin and region, propelling unit cabin is up vertical, for superstructure and the life region 15 of boats and ships, be divided into some layers such as poop deck, crewman deck, bridge deck, superstructure mainly arranges that the exterior space is arranged conventional ship ' s equipment equipment, fire appliance, life saving appliance etc. for the accommodation and the functional cabin relevant to the daily operation of boats and ships of the daily daily life of crewman.
Above-mentioned filling vessel main body structure is full welding steel hull, and full ship adopts double hull configuration.Main deck is from stem to ship stern direction below 3, and collision bulkhead 8 is first structure watertight bulkhead, is thereafter bow thruster cabin and LNG fuel storage cabin 2.Cabin antetheca is second structure watertight bulkhead, and bow thruster cabin rear wall to cabin antetheca is LNG fuel storage cabin 2.In LNG fuel conservation cabin 2, be furnished with a set of IMO-C type independence Low Temperature Liquid goods containment system---the LNG liquid goods tank 1 of round section and supporting goods control system.
Both sides, fuel conservation cabin adopt double-layered protecting structure; between outer wall 9 and inwall 10, it is ballast chamber; together with arranging between inwall 10 and LNG liquid goods tank 1, cut apart bulkhead 11, this cuts apart between bulkhead 11 and inwall 10 and can be used as conventional liquid goods storage compartment, and conventional liquid goods can be fuel oil or fresh water etc.The cargo tank chamber of playing double-layered protecting structure is designed to carry out along captain's direction the structure that some roads are effectively cut apart, to meet the requirement of boats and ships damaged stability and adjusting ballast.Cabin antetheca is arranged cabin and propelling unit cabin successively to ship stern direction.
