Description

  The present invention is a marine vessel, particularly a passenger ship, where the hull has at least one overhang above the water surface, the overhang being acceptable based on a length restriction conditioned on a particular area. The present invention relates to a type in which the ship length is extended beyond a predetermined dimension.

  Length restrictions conditioned on specific areas can be problematic, for example, when crossing a canal or waterway lock. A sea vessel that must comply with this dimension has a smaller effective carrying capacity than a ship that still exceeds the maximum allowable size for passage through its respective channel, such as the Panama Canal. I can't. That is, for example, to maintain the so-called “Panamamax dimensions”, the owner or operator of a ocean vessel that wants to use the Panama Canal has the economic disadvantage that the effective carrying capacity of each ocean vessel is limited to a certain level. Must accept.

  Especially on passenger ships, the number of passengers on board is an important criterion for considering the economic efficiency of shipping companies. Passenger ships, especially the Panama Canal, or other ocean-going ships that use reasonably limited routes, are capped by limits on allowable dimensions.

  Achieving both an economically advantageous increase in passenger capacity and observance of length restrictions conditioned on specific areas can certainly be achieved by reducing cabin dimensions or other space available to passengers It is. This will certainly increase the number of cabins and thus the number of passengers that can be accommodated, but as a result the comfort of individual passengers will be reduced, and this reduction in comfort will lead to a drop in demand and will be reduced for each passenger ship. There is a risk of reducing boarding reservations.

  The object of the present invention is therefore to improve a sea vessel of the type mentioned at the outset so that passengers can now use cruising or long-distance voyage vessels while complying with the length restrictions conditioned on specific areas. It is to provide an ocean vessel, particularly a passenger ship, having a high passenger capacity without compromising the usual comfort that is desired or familiar.

  In order to solve this problem, the configuration of the present invention is as described in the characterizing portion of claim 1. Another advantageous configuration of the invention is described in claims 2 and below.

  In the configuration of the present invention, in order to maintain the effective carrying capacity of the ocean vessel, the passage of the stem overhang, which exceeds the predetermined dimension, is allowed to travel on a route with a limited length conditioned to a specific area. The portion that exceeds the length of the ocean vessel formed is formed as at least one component unit that can be operated reversibly by turning away, removing, or the like as required.

  The cruise ship constructed as in the present invention has a length dimension that exceeds the length dimension allowed for each route, and the passenger capacity of the passenger ship that complies with the permissible ship length. Compared to passenger capacity, it is enhanced and advantageous. In this way, in particular, the passenger accommodation capacity is increased without accepting a decrease in comfort for passengers.

  According to the present invention, for example, before entering the first lock of the Panama Canal, all parts of the overhang that exceed the allowable length dimension of the passenger ship are turned away or removed. This is possible because the part is formed as a component unit that can be operated reversibly.

  After takeoff or removal, the cruise ship has been shortened to the length allowed for the Panama Canal.

  Forming the stem as a reversible handling unit can already be done when building a new ship. However, it is also particularly advantageous to make appropriate improvements later on passenger ships that are already in service. This allows such passenger ships to pass through a length-limited route, such as the Panama Canal, that is conditioned to a specific area later. In particular, according to the present invention, the passenger capacity of passenger ships already in use can be increased later for ship owners of ships for cruising or long-distance navigation. If a passenger ship is extended by a segment installed in between, for example a segment installed in the middle of the ship, the passenger ship extended in this way with regard to passenger capacity can be placed in a specific area, for example the Panama Canal. You will lose permission for routes with conditioned length restrictions. However, due to the solution according to the invention in which a reversible manipulating unit is provided for the purpose of selectively shortening the ship length, an increase in the length dimension made by the extension segments installed in between Can be compensated or offset by turning or removing the bow segment formed as a reversibly operable component unit.

  The part of the overhang that exceeds the allowable length can be turned away, for example, so that the part is placed in the remaining area of the front deck. However, it can also be removed by means of a hoist or a hoist, for example. The component unit that has been lifted and removed can likewise be lowered by means of a hoisting machine, for example to the remaining front deck.

  For example, it is possible for a crane installed on land to lift a component unit that has already been released from the hull before it enters the first lock of the Panama Canal, for example, and lowers it to the front deck. Sailing ships can carry their constituent units together while passing through the Panama Canal. After passing through the canal or waterway, the component units carried together can be reinserted into the stem of the ocean vessel using a suitable hoist.

  In another configuration of the invention, the operable component unit is a bow segment, which is fitted into the hull as follows, i.e. the normal position of the bow segment, i.e. The leading edge of the hull stem and the leading edge of the stem of the bow segment, forming a slope or inclination of the stem in a normal position that exceeds the length allowed to pass through each channel of the Panama Canal Are aligned with each other, and the surface of the outer panel forming the side wall of the hull and the surface of the bow segment are aligned with each other. As soon as the component unit is removed or turned away to reduce the ship length, the stem will simply be formed from the stem section built into the hull. When the bow segment is reinserted into the hull, that is, returned to normal position after removal or turn-off, the hull stem and the leading edge of the inserted bow segment will have a line corresponding to the alignment line of the stem. The bow segment that is formed, i.e. the constituent unit according to the invention, is then fully integrated into the hull again.

  In a further advantageous configuration of a marine vessel with a component unit according to the invention, at least one bulkhead for closing the hull is provided in the region of the ocean vessel facing the operable component unit. Yes. If constituted in this way, the hull or the marine vessel according to the present invention will not interfere with marine operations even after the turnable or removed operational units. Even if the component unit is not attached to the ocean vessel, the ocean vessel will not lose its operational suitability at sea. Thus, the passenger ship can travel on the Atlantic Ocean without a component unit installed at the bow. This is because the bulkhead is integrated into the outer panel of the passenger ship.

  In order to be able to operate the component unit for the purpose of removal, in another configuration of the invention, the component unit is provided with a fitting for attaching the load receiving means of the corresponding hoist. An example of a suitable attachment is a crane eye.

  In the case where the component unit is configured to be able to turn apart, it is advantageous if a working cylinder is provided which can be operated for turning off, which work cylinder is, for example, a suitable link for turning the component unit. Can act on the device.

  According to another advantageous configuration of the invention, the component unit and the hull are provided with locking means which can be operatively coupled to each other. By such locking means, the component unit can be securely fixed to the hull in the normal position where the component unit is incorporated in the bow or stem.

  According to another advantageous configuration of the invention, the locking means is provided with a selectively operable remote control device, which can be operated, for example, from a bridge of a marine vessel, Can be introduced, and a reliable fixing can be performed again after a new installation.

  Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing a front portion of a ocean vessel,
FIG. 2 is a view showing the front portion of the ocean vessel as in FIG. 1, and is a side view showing a state where the bow tip is turned away and placed on the front deck as in the present invention.

  In FIG. 1, the front part of the passenger ship is shown in side view. The hull 1 called a hull of a passenger ship has an overhang on the surface of the water. That is, the front edge 2 of the stem 3 in the case shown in the figure is inclined from the bow tip 4 of the hull 1 toward the lower rear side. 1 to the transition to the underwater portion 15. The dimension from the bow tip 4 to the outermost edge of the stern (not shown) of the ship is the ship length, which is conditioned on a specific area such as the Panama Canal, for example. It is not permissible to exceed the allowable dimensions for routes with length limitations. This excess corresponds to the dimension between the tip 6 of the spherical bow 7 and the bow tip 4 in the water.

  The illustrated passenger ship is constructed in such a way that the excess part of the overhang of the stem 3 is configured as at least one component unit 8 which can be operated by means of turning off, removing or the like if necessary. It is outstanding.

  The construction unit 8 has a swivel mast 9 for the front branch 10.

  FIG. 2 also shows the front part of the passenger ship, but in this case, unlike FIG. 1, the component unit 8 is shown in a position swung back. The component unit 8 can be turned back to the position shown in FIG. 2 by using a driving means (not shown) such as a hydraulic cylinder and a link device around a hinge defining a horizontal axis 11. The front branch line 10 is removed when passing through a route such as the Panama Canal, and the turning mast 9 is laid down sideways.

  As can be seen from FIG. 2, the return length of the component unit 8 about the horizontal axis 11 shortens the ship length, i.e. it is possible to clear the length restriction conditioned on a specific area. It is shortened to a length corresponding to the dimension.

It is a side view which shows the front part of a sailing ship. It is a figure which shows the front part of a marine vessel like FIG. 1, Comprising: It is a side view which shows the state by which the bow tip was turned away like this invention, and was mounted in the front deck.
