Abstract

PURPOSE:To decrease power from a Diesel generating set, mounted on a ship, so as to contrive the reduction of noise and vibration in the ship by supplying power, which is required for the ship, when it enters and leaves a port, to exceed the power required for the ship during its sealing, from a power generating exclusive ship. CONSTITUTION:A Diesel engine 1 and a generator 2, which are set up in a ship, are used only for power 3 for an accessory equipment and power 4 for lighting and communication required for the ship when it is in sailing. For power 5 used for a mooring machine, which is used at the time of port arrival and departure for coming alongside and leaving the quay, bow thruster and a stern thruster, a generator 8 is turned by a Diesel engine 7, provided in a power generating exclusive ship 6, to generate power, and by feeding it to the concerned ship by a power feeding equipment 9 to be received by a power receiving equipment 10 provided in the ship 6, the power 5 is supplied. In this way, surplus propulsive power is made unnecessary while reducing noise and vibration generated in the ship.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a power source for ships that supplies power for mooring machines, bow thrusters, and stern thrusters that exceeds the power required during navigation when a ship enters or departs from a port. Regarding the supply method.

[Prior Art] When a ship enters or leaves a port, electric power is required to operate mooring machines, bow thrusters, stern thrusters, etc. for berthing or unberthing, which are not used during navigation. Therefore, on ships, as shown in the power supply system diagram in Figure 3,
Power for mooring machine, bow thruster and stern thruster 2
1 is combined with the power 22 for other in-board auxiliary equipment and the power 23 for lights and communications, and a plurality of diesel engines 24 (three in FIG. 3) rotate a generator 25 to generate electricity.

[Issues to be solved by the invention] Since the above-mentioned diesel power generator generates noise and vibration during operation, it is better to reduce the number of diesel generators as much as possible, especially on passenger ships, and to install diesel engines that are not required during navigation. Therefore, there is a problem in that it is necessary to provide the ship with extra propulsion force.

This invention solves the above-mentioned problems of the prior art,
It is possible to reduce the number of diesel generators installed on ships, reduce noise and vibration inside the ship, and
The purpose is to provide a method for supplying power to ships that does not require extra propulsion power.

[Means for Solving the Problems] A method for supplying power for a ship according to the present invention provides a method for supplying power for a ship by a power-generating ship that exceeds the power required during navigation when the ship enters and leaves a port. This is a supply method in which the power required during navigation is supplied only by the generator installed on the drive shaft of the main engine, and the power that exceeds the power required during navigation when entering and exiting port is supplied by a ship dedicated to power generation. This is the supply method.

[Function] The method for supplying power for a ship according to the present invention allows a dedicated power generation ship to supply power that exceeds the power required during navigation when the ship enters and exits a port. In addition, the power required during navigation is supplied only by the generator installed on the drive shaft of the main engine.
Electricity in excess of the electricity required during navigation when entering and exiting a port is supplied by a dedicated power generation vessel. Therefore, it is possible to reduce the number of diesel engines used to generate electricity for use in a ship, reducing noise and vibration inside the ship, and reducing the propulsion force required for the ship.

[Example] A method for supplying power for a ship according to an example of the present invention will be explained based on FIGS. 1 and 2. FIG. 1 is a power supply system diagram showing a method of supplying power for a ship according to a first embodiment of the present invention. In this case, the diesel engine 1 and generator 2 installed on board the ship are used only for power 3 for auxiliary equipment and power 4 for lights and communications (one unit in Figure 1) used while the ship is sailing. Power for the mooring machine, bow thruster and stern thruster for berthing and unberthing used when leaving port 5
The diesel engine 7 installed on the power generation ship 6 rotates the generator 8 to generate electricity, which is transmitted to the ship through the power transmission equipment 9, and is received by the power receiving equipment 10 installed on the ship. I have to.

FIG. 2 is a power supply system diagram showing a method for supplying power for a ship according to a second embodiment of the present invention. In this case, a dedicated diesel engine or generator is not installed for the power 3 for the inboard auxiliary equipment and the power 4 for lights and communication used during navigation, but is installed on the rotating shaft 13 of the main engine 12 for propulsion of the ship's 10-bell 11. A generator 14 is used to generate electricity to cover this amount of electricity. As in the first embodiment, electric power for mooring machines, bow thrusters, and stern thrusters for berthing and unberthing used during port entry and departure is generated by a generator 8 using a diesel engine 7 installed in a power generation ship 6. The generated power is transmitted to the ship through a power transmission facility 9, and is received by a power receiving facility 10 installed on the ship to provide electricity.

Since the method of supplying power for a ship according to the first and second embodiments of the present invention is carried out as described above, the number of diesel engines for power generation installed on board the ship can be reduced or completely eliminated. It is possible to reduce the noise and vibration generated by the vehicle, and no extra propulsion force is required.

[Effects of the Invention] According to the present invention, noise and vibration generated inside the ship can be reduced, and extra propulsive force is not required.
