Description

  The present invention relates to a marine fuel tank.

  For the purpose of protecting against marine pollution caused by fuel oil, it is necessary to keep the fuel tank at a predetermined distance from the ship's skin to minimize the amount of oil spilled from the fuel tank when the ship's skin is damaged during a collision or landing. is there. As shown in FIG. 4, the conventional technology expands the hull in the width direction, and provides a void space between the fuel tank and the ship side skin so that the fuel in the event of a collision or damaging the ship side skin at the time of landing. It is known to minimize the amount of oil spilled from the tank.

  However, in the case of the above-described method, the hull width is increased to increase the hull weight, resulting in an increase in the cost of the ship, which is not economical. In addition, in order to install a void space between the fuel tank and the ship side skin without enlarging the hull in the width direction and to secure the same fuel tank capacity as before, it is necessary to reduce the engine room capacity. As a result, although not shown, there is a problem that it is impossible to dispose an auxiliary machine or tank in the engine room.

  In view of the prior art, the present invention provides a fuel tank capable of minimizing the amount of oil spilled from the fuel tank at the time of collision or damaging the ship's outer skin without changing the shape of the hull. And it aims at ensuring the required fuel tank capacity.

According to a first aspect of the present invention, a marine fuel tank is provided with a rectangular fuel tank on the exposed deck of the marine vessel and separated from the hull outer plate .
Marine fuel tank of the second aspect is, in whole or in part within the deck house provided deck crane undercarriage on exposed deck of the ship in which the fuel tank.

According to a first aspect, marine fuel tank, on the weather deck of the ship, rectangular, and, since it becomes possible to provide a fuel tank away from the ship outside plate, changing the shape of the hull In addition, it is possible to minimize the amount of oil spilled from the fuel tank when the ship side skin is damaged during a collision or grounding, and the necessary fuel tank capacity can be secured.
According to a second aspect, marine fuel tank, it becomes possible to fuel tank to all or part of the deck is provided house the deck crane undercarriage on weather deck of the ship, the hull Without changing the shape, it is possible to minimize the amount of oil spilled from the fuel tank in the event of a collision or damaging the outer skin of the ship, and ensure the required fuel tank capacity. .

Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a side view of an embodiment of the device of the present invention. FIG. 2 is a side view of two embodiments of the device of the present invention. FIG. 3 is a side view of a conventional fuel tank. FIG. 4 is a diagram schematically showing a conventional fuel tank in a sectional view.

As shown in Figure 1, on the weather deck 38 of the ship 1 is disposed residence area 3, on the weather deck 3 8, and a stand-alone on the front deck or on the rear deck of the living quarters 3 A fuel tank 2 is provided. By doing so, the fuel tank 2 is separated from the hull outer plate 37, and the amount of oil outflow from the fuel tank 2 at the time of collision or damaging the hull outer plate at the time of landing is minimized without changing the hull shape. It becomes possible to limit to the limit.

As shown in FIG. 2, a residential area 23 and a deck crane 24 are disposed on the exposed deck 38 of the hull 21, and a deck house 25 is provided below the deck crane 24. All or part of the deck house 25 is a fuel tank 22. By doing so, the fuel tank 22 is separated from the hull outer plate 37, and the amount of oil outflow from the fuel tank 22 at the time of collision or damaging the hull outer plate at the time of landing is minimized without changing the hull shape. It becomes possible to limit to the limit.

In FIG. 1, reference numerals 1, 2, and 3 indicate a hull 1, a fuel tank 2, and a residential area 3, respectively. In FIG. 2, reference numerals 21, 22, 23, 24, and 25 indicate a hull 21, a fuel tank 22, a residential area 23, a deck crane 24, and a deck house 25, respectively. In FIG. 3, reference numerals 31, 32, and 33 denote a hull 31, a fuel tank 32, and a residential area 33, respectively. In FIG. 4, reference numerals 32, 36, 37, 38, and 39 denote a fuel tank 32, a void space 36, a hull outer plate 37, an exposed deck 38, and an engine room 39, respectively.

It is the figure which showed the implementation method of the fuel tank for ships. Example 1 It is the figure which showed the implementation method of the fuel tank for ships. (Example 2) It is the figure which simplified and showed the conventional fuel tank with the side view. It is the figure which simplified and showed the conventional fuel tank with sectional drawing.
