According to the LNG transport ship, the controllability and port flexibility of the ship are greatly improved, the economical efficiency and security of the ship are improved, and the requirement for domestic LNG transportation can be met.
Description
Technical field
The utility model relates to a kind of LNG carrier, particularly relates to a kind of LNG carrier that is suitable for domestic LNG transportation.
Background technology
The trend of the existing oriented large scale development of LNG ship, main flow ship type mostly is 14 ten thousand steres and 17 ten thousand steres at present.The shortcomings such as this kind ship type is used for domestic LNG transportation and exists the port condition deficiency because yardstick is large, and maneuvering performance is not good, and is less economical.Existing LNG carrier has employing hybrid fuel electric propulsion system more, is to advance but be conventional axle.This kind Promoting Form Shortcomings on Ship Maneuverability, particularly the maneuvering performance in the harbour is not good.If this kind LNG carrier for domestic trade, often navigates by water in narrow waters and carries out the inward ﹠ outward operation, the characteristics that its maneuvering performance is not good are so that there is larger potential safety hazard in boats and ships.
The utility model content
The utility model provides a kind of LNG carrier that is suitable for the frequent inward ﹠ outward of narrow waters for solving the technical matters that exists in the known technology, to satisfy the needs of domestic LNG transportation.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of LNG carrier that is suitable for the frequent inward ﹠ outward of narrow waters, the cargo hold total volume of this ship is not more than 30000 cubic meters, be provided with the gondola propulsion unit that two lateral symmetry are arranged on the quarter, dispose bow thruster at bow; Described gondola propulsion unit comprises a PODDED PROPULSOR and a cover module of coming about, and described PODDED PROPULSOR comprises screw propeller and drive motor thereof, and the described module of coming about is provided with two motors of coming about; Described bow thruster is provided with drive motor; The drive motor of bow thruster, the drive motor of screw propeller and the described motor of coming about are by the power system power supply on the ship.
The electric power of described electric system is to be produced by configuration electrical generator aboard ship, and described electrical generator is by aboard ship engine-driven of configuration.
Described driving engine is the binary fuel engine that uses diesel oil or natural fuels to act as a fuel.
Described cargo hold is C type independent liquid cargo tank.
The described module of coming about is positioned at hull, and the drive motor of described screw propeller is positioned at gondola under water, and is permanent magnet motor.
Advantage and the good effect that the utlity model has are: 1) by adopting the structure of configuration gondola electric propulsion unit and bow thruster, significantly improved manoevreability in the road-holding property of boats and ships and the port, the economy and the safety that have improved boats and ships; 2) adopt C type cargo hold, meet domestic shipyard and build ability; 3) make volume of compartment be not more than 30000 cubic meters, be fit to enter domestic most coastal harbor, and the THE LOWER YANGTZE VALLEY harbour; 4) adopt binary fuel engine, effect is outstanding aspect energy-saving and emission-reduction.In a word, the utility model can satisfy the needs of domestic LNG transportation.
Description of drawings
Fig. 1 is lateral plan of the present utility model;
Fig. 2 is the arrangement plan of the utility model electric system;
Fig. 3 is the arrangement plan of the utility model gondola propulsion unit and bow thruster.
Among the figure: 1, C type independent liquid cargo tank, 2, driving engine, 3, the gondola propulsion unit, 4, bow thruster, 5, main switchboard.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1～Fig. 3, a kind of LNG carrier that is suitable for the frequent inward ﹠ outward of narrow waters adopts C type independent liquid cargo tank 1 as liquid goods containment system, and full ship arranges 4 independent liquid cargo tanks 1, and total volume is not more than 30000 cubic meters.Owing to adopt C type cargo tank, so cargo hold do not need time shielding protection, and can be in larger range of pressure trouble free service.
Be provided with the gondola propulsion unit 3 that two lateral symmetry are arranged on the quarter, dispose bow thruster 4 at bow; Gondola propulsion unit 3 comprises a PODDED PROPULSOR and a cover module of coming about, and PODDED PROPULSOR comprises screw propeller and drive motor thereof, and the module of coming about is provided with two motors of coming about; Bow thruster 4 is provided with drive motor; The drive motor of bow thruster, the drive motor of screw propeller and the motor of coming about are by the power system power supply on the ship.In the present embodiment, the electric power of electric system is to be produced by configuration electrical generator aboard ship, and electrical generator is to be driven by configuration driving engine 2 aboard ship.Driving engine 2 is the binary fuel engines that use diesel oil or natural fuels to act as a fuel.The electric system of present embodiment adopts binary fuel engine as primary mover, and three binary fuel engines are arranged in the cabin of afterbody, as shown in Figure 2, adopts binary fuel engine 2 to drive electrical generator.Electrical generator is connected to a shared electrical network, and then is connected to main switchboard 5.To all loads, comprise that the drive motor of bow thruster, the drive motor of screw propeller, the motor of coming about, accessory equipment and marine system power by this electrical network.All loads distribute by the electrical generator that is moving simultaneously.Bow thruster 4 can provide one perpendicular to the horizontal thrust of the boats and ships longitudinal axis.In the situation of the low speed of a ship or plane or zero speed of a ship or plane, gondola propulsion unit 3 and bow thruster 4 are used can finish pivot turn and horizontal shifting by from actions such as pools, has improved manoevreability and the safety in the port.Gondola electric propulsion unit can rotate by 360 degree, provides accurate thrust in all directions.In the present embodiment, the module of coming about is positioned at hull, and the drive motor of screw propeller is positioned at gondola under water, and is permanent magnet motor.
