Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tanker cargo handling facility in which installation locations of a boiler and an inert gas system are improved.

[0002]

2. Description of the Related Art Generally, a cargo handling facility of a tanker supplies steam to an oil pump 3 for transporting oil in an oil tank 2 of a tanker 1 to a ground tank and a drive turbine 4 of the oil pump 3 as shown in FIG. It mainly comprises a boiler 5 for performing the operation, and an inert gas device 6 for treating the exhaust gas generated from the boiler 5 into an inert gas and supplying the same to the oil tank 2 for explosion protection.

Conventionally, these cargo handling facilities are shown in FIG.
All were installed on the tanker 1 as shown in FIG.

[0004]

However, the above cargo handling equipment is installed on the tanker in spite of being used only at the time of cargo handling. Therefore, the weight of the tanker increases, resulting in an increase in operating cost and a large space. There was a problem that the cargo handling facility would reduce the cargo space and raise the ship price.

Therefore, an object of the present invention is to solve the above problems and to provide a cargo handling facility for a tanker capable of reducing the operating cost by reducing the weight of the tanker, increasing the cargo space and reducing the ship price.

[0006]

In order to achieve the above object, a tanker cargo handling facility according to the present invention is a boiler for supplying steam to a drive turbine of an oil pump provided in a tanker at an unloading base of the tanker. And an inert gas device for treating the exhaust gas of the boiler into an inert gas and supplying it to the oil tank of the tanker.

[0007]

According to the above construction, since the boiler and the inert gas device, which were conventionally provided in the tanker, are moved to the cargo handling base, and the tanker does not need these cargo handling equipment, the operation cost is reduced by reducing the weight of the tanker. , The cargo space can be increased and the ship price can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, as a cargo handling facility for the tanker 1, an oil pump 3 for transporting the oil contained in the oil tank 2 to the aboveground tank is installed in the tanker 1,
The boiler 5 for supplying steam to the drive turbine 4 of the oil pump 3 is supplied to the cargo handling base 7 on the ground, and the exhaust gas of the boiler 5 is processed into an inert gas and supplied into the oil tank 2 of the tanker 1. And an inert gas device 6 are installed.

The tanker 1 is partitioned into an oil tank 2, a pump chamber 8 and an engine room 9, and the oil which is sucked from the oil tank 2 through the suction pipe 10 into the pump chamber 8 is fed to the oil feed pipe 1.
An oil pump 3 for transporting to the aboveground tank via 1 is installed. A turbine 4 for driving the oil pump 3 with steam pressure is installed in the engine room 9. The turbine 4 is provided with an introduction pipe 12 for introducing steam, and a steam supply pipe 13 led from a boiler 5 on the ground is connected to the introduction pipe 12 via a joint (not shown).

A nozzle 14 for injecting an inert gas is provided above the oil tank 2 of the tanker 1, and an inert gas supply pipe 15 led from an inert gas device 6 on the ground is shown in the nozzle 14. Not intended to be connected through a joint.

Further, a water heater 16 for recovering the heat energy of the exhaust gas generated from the boiler 5 is provided at the cargo handling base 7 on the ground, and hot water obtained by heat exchange is provided to the hot water supply system in the base. It has become so. A part of the exhaust gas discharged through the water heater 16 is supplied to the inert gas device 6 and treated as an inert gas.

Next, the operation of the embodiment will be described. When the tanker 1 carrying oil is docked at the cargo handling base 7, the steam supply pipe 13 of the boiler 5 of the cargo handling base 7 is connected to the introduction pipe 12 of the turbine 4 of the tanker 1 via a joint, and the inert gas of the cargo handling base 7 is connected. The inert gas supply pipe 15 of the device 6 is connected to the nozzle 14 of the tanker 1 via a joint. Further, the oil supply pipe 11 of the tanker 1 is connected to the aboveground tank.

The turbine 4 is driven by the steam pressure supplied from the boiler 5, the oil pump 3 is driven by this turbine 4, and the oil in the oil tank 2 is transported to the ground tank via the oil feed pipe 11. In parallel with this, the exhaust gas discharged from the boiler 5 is first heat-exchanged in the water heater 16,
A part of the exhaust gas after heat exchange is treated as an inert gas by the inert gas device 6, and the inert gas prevents the explosive gas in the oil tank 2 from exploding in the nozzle 1
It is supplied from 4 into the oil tank 2.

In particular, since the boiler 5 and the inert gas device 6 which were conventionally installed in the tanker are relocated to the cargo handling base 7 on the ground, the weight of the tanker 1 can be reduced accordingly.
The operating cost can be reduced and the ship price can be reduced.
Further, since the boiler 5 and the inert gas device 6 which have occupied a large installation space are removed, the space can be effectively used and the cargo space can be increased.

The boiler 5 and the inert gas system 6 were relocated to the cargo handling base 7. However, the number of cargo handling bases 7 is much smaller than the number of tankers 1, so the total economic efficiency of land and land is limited. There are great advantages. Further, since the water heater 16 for exchanging heat with the exhaust gas of the boiler 5 is provided in the cargo handling base 7, it is possible to recover the thermal energy of the exhaust gas which has been conventionally discarded, and is effective for the hot water supply system in the cargo handling base 7. Can be used.

[0017]

In summary, according to the present invention, since the boiler and the inert gas device, which are conventionally provided in the tanker, are installed in the cargo handling base and the tanker does not need these cargo handling facilities, the weight of the tanker is reduced. The operating cost can be reduced, the cargo space can be increased, and the ship price can be reduced.
