Definitions

  • the invention relates to a ship comprising a bow door arrangement.
  • Roll-on/roll-off (Ro-Ro) ships and similar ships are commonly used to transport cars, trucks, other wheeled vehicles and other types of cargo. Unloading of vehicles can take place from a number of various types of ramps, for instance a bow ramp.
  • the bow ramp of a roll-on/roll-off ship, such as for instance a ROPAX ship, are normally stowed inside the hull and are covered by bow doors.
  • Today's bow ramps are operated by means of bulky cylinders for deploying and stowing the bow ramp with struts supporting the bow ramp. Further, operation of today's side swinging bow doors are made by means of large hinge arms mounted on the inside of the hull. These solutions take up space inside the hull and create a limitation regarding the capacity that can be unloaded from a Ro-Ro ship.
  • An object of this invention is to provide a ship comprising a bow door arrangement that addresses the problems described above. This object is achieved by the technical features contained in the characterizing portion of independent claims 1, 13, 14, 22 and 30.
  • the dependent claims contain advantageous embodiments, further developments and variants of the invention.
  • the application relates to a bow door arrangement for a ship.
  • the bow door arrangement comprises a starboard bow door, a port bow door, first starboard and port guiding arrangements and second starboard and port guiding arrangements.
  • Each of the first and second starboard and port guiding arrangements comprises a starboard and a port ship guide part arranged to be attached to a ship and a starboard and port bow door guide part arranged to be attached to a bow door.
  • the ship guide parts and bow door guide parts are arranged to interact to guide the starboard and port bow doors between an open position and a closed position.
  • the first starboard bow door guide part of the first starboard guiding arrangement is arranged on a starboard bow door top part of the starboard bow door and the second starboard bow door guide part of the second starboard guiding arrangement is arranged on a bottom part of the starboard bow door.
  • the first port bow door guide part of the first port guiding arrangement is arranged on a port top part of the port bow door and the second port bow door guide part of the second port guiding arrangement is arranged on a port bow door bottom part of the port bow door.
  • the application further relates to a bow ramp arrangement for a ship comprising a bow ramp and a wire actuation system.
  • the bow ramp comprises a first bow ramp part and a second bow ramp part.
  • the first bow ramp part is arranged to be pivotably connected to a ship.
  • the first bow ramp part may be separable from the second bow ramp part and pivotable relative to the second bow ramp part when engaged to the second bow ramp part according to regulations and as described in WO 96/32317 A1 .
  • the first bow ramp part is fixedly engaged to and pivotable relative to the second bow ramp part.
  • the wire actuation system comprises at least one wire and a wire actuator.
  • the wire is connected to the wire actuator, to the second bow ramp part and to a wire actuation point adapted to be arranged in a ship.
  • the first bow ramp part is connected to a first bow ramp actuator.
  • the wire actuator is arranged to control the deployment of the bow ramp together with the first bow ramp actuator.
  • the two arrangements of the application provides for enabling a wider and/or longer bow ramp for a ship.
  • the arrangements display synergetic effects when combined but they can also be standalone alternatives. I.e., a ship can have only one of the two alternatives in order to enable a wider and/or longer bow ramp. Having both the bow door arrangement and the bow ramp arrangement will provides a ship with the greatest benefit of the largest loading/unloading capacity through the bow.
  • a larger bow space within a ship is made available since the hinge arms used for today's side swinging bow doors can be removed by replacing the hinge arms with first and second starboard and port guiding arrangement which to operate the opening and closing of the bow doors.
  • Removing the hinge arms opens up the possibility to use more of the ship's width for a bow ramp as the hinge arms take up space within the bow space.
  • the first and second starboard and port guiding arrangements are located on the top and bottom parts of the bow doors, the guiding arrangements can be moved forward and aft within the bow space, thereby enabling use of more of the bow space's length.
  • the opening of the doors can now be made in a direction essentially parallel to a length direction of the ship.
  • struts used to support the bow ramp located on the starboard and port sides of the ramp centreline can be removed.
  • the struts are designed to hold the weight of the second bow ramp part during deployment of the bow ramp.
  • Using a wire that takes up considerably less space than the struts frees up bow space so that the second bow ramp part and when required, the third bow ramp part, can be made longer.
  • the third bow ramp part will have its end closer to the first bow ramp part in the bow ramps stowed position. This allows for a longer ramp as the space previously occupied by the struts can be used to lengthen the ramp.
  • a ship can be provided with a bow door arrangement in order to provide flexible solutions both for construction of new ships or conversion of existing ships.
  • the widest and longest ramp will be made possible on a ship provided with both arrangements.
  • the bow door arrangement may further comprise a first drive mechanism.
  • the first drive mechanism comprises at least one drive source and transmission.
  • the first drive mechanism is arranged to interact with drive parts arranged on the top parts of the starboard and port bow doors in order to operate the starboard and port bow doors between the open and closed positions.
  • the drive mechanism can be any suitable drive mechanisms known in the art, such as for instance a rack and pinion arrangement, hydraulic or electro-mechanic actuators or a wire and tackle arrangement.
  • the first drive mechanism may be arranged to operate the opening and closing of both the starboard and port bow doors simultaneously.

  • the bow door arrangement may further comprise a second drive mechanism.
  • the second drive mechanism comprises at least one drive source and transmission.
  • the second drive mechanism is arranged to interact with drive parts arranged on the bottom parts of the starboard and port bow doors in order to operate the starboard and port bow doors between the open and closed positions.
  • a second drive mechanism can be installed to assist in the operation of the bow doors or to be used instead of the first drive mechanism. It is possible as an alternative to have only a first drive mechanism arranged to interact with drive parts arranged on the bottom parts of the starboard and port bow doors.
  • the second drive mechanism may be arranged to operate both the starboard and port bow doors simultaneously.
  • the second drive mechanism may be arranged such that a single drive mechanism operates both the first and port bow doors. This can be achieved by having the drive source interact with the drive parts on the top parts of both the starboard and port bow doors simultaneously.

  • a top part of a bow door comprises an upper side extending to the top beam part.
  • the first and second guiding arrangements may comprise at least one torque-free guiding device arranged between the ship guide part and the bow door guide part, e.g. a wheeled trolley hanging in a spherical bearing similar to one used in an overhead crane arranged to be rotatable along all axes.
  • torque-free guiding means in the first starboard and port guiding arrangements, the installation of the bow doors can be made easier since the tolerance requirements can be reduced.
  • the torque-free guiding means can be used to make sure that the load on the movable parts of the respective guiding arrangements are evenly distributed. Having the first guiding arrangement torque free, may also be beneficial when sea load forces acts on the bow doors as they reduce sea load forces transferred into the guiding arrangement.
  • the second starboard bow door guide part of the second starboard guiding arrangement may be arranged to fit inside a cavity of the port bow door floor.
  • the second port bow door guide part of the second port guiding arrangement is arranged to fit inside a cavity of the starboard bow door floor.

  • the second ramp part and the third ramp part may have essentially the same length.
  • the second ramp part can be tilted upwards during deployment of the bow ramp. This makes a longer third bow ramp part possible that does not interfere with any obstacles within the bow space during deployment of the ramp.
  • the second and third bow ramp parts can be made of essentially the same length, thereby extending the total length of the ramp compared with today's ramp where the third part is essentially shorter than the second part due to the position of the traditionally used struts.

  • the wire can be pre-tensioned when the bow ramp is deployed.
  • the wire and the wire actuator will absorb at least part of the force exerted by the ramp on the quay, dock, link span or pontoon. This can increase the maximum weight of cargo being loaded or unloaded on a quay, dock, link span or pontoon compared to today, thus leading to increased loading/unloading capacity without having to reinforce the quay, dock, link span or pontoon.
  • deflection of the bow ramp can be reduced using pre-tensioned wires when loading cargo on the bow ramp, it is possible to use the same maximum cargo weight as today with weaker/lighter ramp structure.
  • the second bow ramp part may further comprise bow ramp guides arranged to interact with a ramp guide arrangement arranged to be attached to the ship.
  • the bow ramp guides may for instance glide or roll along the ramp guide arrangement in order to control the deployment of the bow ramp and of the second bow ramp part in particular.
  • the invention also relates to a ship comprising a bow door arrangement t according to the above.
  • a ship having the combination of both the bow door arrangement and the bow ramp arrangement can be provided with the longest and broadest ramp possible.
  • a ship comprising only a bow door arrangement can be provided with a broader ramp, although today's struts holding up the bow ramp will reduce the maximum length of the ramp.

  • the wire actuation point may be movable relative the wire attachment point to a position where the actuation point and the wire attachment point lie essentially in the same vertical plane, when the bow ramp is deployed.
  • the wire actuation point By being able to move the wire actuation point relative to the wire attachment point, the direction of the force acting on the wire attachment point, and thereby on the second ramp part, by the wire can be changed such that the force is essentially vertical. This essentially reduces the force exerted by the wire on the second bow ramp part in the horizontal direction to zero leading to that a locking arrangement between the first and second bow ramp parts can be made smaller or removed completely. Moving of the wire actuation point can take place during deployment of the bow ramp or after the bow ramp is deployed.

  • the first bow ramp actuator 47 From this position, a great amount of force needs to be provided by the first bow ramp actuator 47 in order to raise the bow ramp 8 due to the short lever arm.
  • the short lever arm for the first bow ramp actuator 47 to raise the bow ramp 8 and the short lever arm for the struts 46 to prevent the second and third bow ramp parts 10, 11 to rotate around the hinges connecting the first and second bow ramp parts result in high forces acting on ramp structure and ship structure.

  • the bow ramp arrangement 4 comprises a bow ramp 8 and a wire actuation system 50.

  • the bow ramp 8 comprises a first bow ramp part 9, a second bow ramp part 10 and a third bow ramp part 11.
  • the first bow ramp part 9 is arranged to be pivotably connected to a ship 1 and further being separable from the second bow ramp part 10 and pivotable relative to the second bow ramp part 10 when engaged to the second bow ramp part 10 or being fixedly engaged to the second bow ramp part 10.

  • the wire actuator 52 is arranged to control the deployment of the bow ramp 8 together with the first bow ramp actuator 47 and the second bow ramp actuator.
  • the wire actuator 52 is illustrated by a winch attached to the ship 1.
  • the placement of wire actuator 52 in the figures is for illustrative purposes only.
  • the wire actuator 52 is normally placed within the ship's structure or in the second bow ramp part 10 as indicated by the dashed outline in the figure.
  • the wire actuator 52 may alternatively be an electrically powered winch, a hydraulically powered winch or a hydraulic cylinder controlling the actuation of the wire 51.
  • a block and tackle system/jigger winch may be incorporated into the wire actuation system 50 in order to control the forces exerted by the wire actuator 52 and achieve the required stroke on the cylinder to deploy the bow ramp 8 completely.
  • Figure 11a schematically shows the bow ramp arrangement of the first example is in its stowed position ready to be deployed. Similar to the traditional bow ramp arrangement 44, a first bow ramp actuator 47 operates the first bow ramp part 9.
  • the third bow ramp part 11 is essentially equal in length to the second bow ramp part 10, making the entire bow ramp 8 longer than in the traditional bow ramp arrangement 44 where the third bow ramp part 11 is shorter than the second bow ramp part 10 due to the location of today's used struts.
  • the first bow ramp part 9 has engaged with the second bow ramp part 10.
  • the wire 51 allows for the second bow ramp part 10 to be held in a more upright position that is different from the position of the second bow ramp part 10 of the traditional bow ramp arrangement 44 during deployment of the bow ramp 8. This is due to that the first bow ramp actuator 47 push the second bow ramp part 10 while the second bow ramp part 10 hang in the wire 51 and consequently moves forward and upwards during an initial phase of deployment of the bow ramp 8 and thereby create more space for the lengthened third bow ramp part 11 as illustrated by the outline in figure 10b .
  • the third bow ramp part 11 does not collide with the bow door supports 49 during deployment. Having a longer third bow ramp part 11 in the traditional bow ramp arrangement 44 would have resulted in that the third bow ramp part 11 would have been hindered during deployment by the bow door supports 49.
  • the bow ramp 8 is completely deployed. From this position, when the bow ramp 8 is to be stowed, the wire 51 will assist in lifting the bow ramp 8 and will provide most of the lift required to lift the bow ramp 8. This leads to that the first bow ramp actuator 47 can be made smaller as it does not have to provide the same amount of force as for the traditional bow ramp arrangement 44.
  • Fig. 12a-12c schematically show a bow ramp arrangement 4 according to a second example.
  • the wire actuation point 53 is movable in a direction essentially parallel to the length direction of the ship 1.
  • the wire actuation point 53 is movable to a forward position from a rear position.
  • the bow ramp 8 is partly deployed, and the wire actuation point 53 is located above the wire attachment point 54 but not in the same vertical plane as the wire attachment point 54.
  • the second bow ramp part 10 will move outwards during its deployment, leading to that the wire actuation point 53 will be located at a distance horizontally from the wire attachment point 54. If the wire actuation point 53 not was movable forward in the length direction of the ship 1, it would have resulted in a horizontal force component acting on the second bow ramp part 10 by the wire 51.
  • This horizontal force component is unwanted and tries to open the hinges between first bow ramp part 9 and second bow ramp part 10 if no pushing force is applied from the first bow ramp actuator 47, or if no locking device is used between the first bow ramp part 9 and the second bow ramp part 10. This is also the case in figures 11a-11d .
  • Fig. 13a-13d schematically show a bow ramp arrangement 4 according to third example.
  • the bow ramp arrangement 4 comprises a ramp guide arrangement 55 arranged to be attached to the ship 1.

  • the bow ramp 8 has started to deploy.
  • the second bow ramp part 10 is guided by the ramp guides 56 interaction with the ramp guide arrangement 55.
  • the ramp guides 56 can be anything that can glide or roll on a surface, e.g. a glide surface or wheels or rolls attached to the second bow ramp part 10.
  • the second bow ramp part 10 has reached a position similar to the position in fig. 10b .
  • the ramp guides 56, the ramp guide arrangement 55 and the wire 51 interact to bring the second bow ramp part 10 into a more upright position in which the third bow ramp part 11 can be deployed without interfering with the bow door supports 49.
  • the third bow ramp part 11 has been partly deployed. As can be seen by the outline in fig. 13c , the third bow ramp part 11 does not collide with the bow door supports 49 as would have been the result if the upright position not was reached before rotating the third bow ramp part 11.
  • the length of the first bow ramp part is between 4 and 10 m
  • the length of the second bow ramp part is between 5 and 10 m
  • the length of the third bow ramp part is between 2 and 10 m.
