Definitions

  • the invention concerns a ship or other vessel having launch-and-retrieval means, as set out by the preamble of claim 1.
  • Ships used for long-line fishing commonly deploy (set) and retrieve (haul) the long-line through designated openings in the sides of the ship, on or above the ship’s main deck level.
  • Long-lines may be very long, depending on the capacity of vessel, and comprise baited hooks at regular intervals.
  • One disadvantage with this configuration is that the long-line is travelling through air for a considerable distance behind the fishing vessel before it enters the sea, and the exposed bait (or fish) attached to the long-line hooks attract sea birds. Particularly during long-line setting, the sea birds are thus
  • One object of the invention is thus to reduce or eliminate the exposure of the long-line to sea birds during setting and hauling.
  • the prior art includes WO 99/22984 A2, which describes a central hauling pool for a fishing vessel.
  • the central hauling pool comprises a generally vertical main tube through the vessel, with a lower opening or mouth towards the sea and an upper opening towards the atmosphere.
  • the upper part of the main tube has a tube transition constituting a large relative widening of the cross-sectional area below the water line in the main tube to an upper tube part.
  • the prior art also includes WO 02/38439 Al, which describes a vessel for setting a long-line.
  • the fishing vessel has a well or a mainly vertical, tube-shaped setting duct having an upper mouth or inlet for the long-line and extending down through the bottom of the vessel and having a lower exit portion for the long-line. The exit portion extends down below the keel or the bottom of the vessel.
  • the prior art also includes DE 89769 C, which describes a fishing vessel having a channel at the vessel bow.
  • the channel E is of square or rectangular cross-section, and extends below the waterline and a short length into the ship. This channel may be closed by doors.
  • the space underneath the channel is open to the water, while the space behind is divided into two outlets directed obliquely against the ship's walls.
  • the prior art also includes WO 03/059731 Al, which describes a trawling vessel for use with a trawl net for catching marine bio-resources.
  • a trawl sack is attached aft on a trawl net for keeping the catch, and the vessel comprises lines for towing and hauling the trawl net.
  • a lock chamber is provided in the vessel stem.
  • the lock chamber has a main portion of its volume below the vessel’s design water line.
  • the lock chamber is arranged for hauling the trawl sack with its catch from the sea, through a sluiceway in the stern.

  • the plate plate member may be a force member, shaped or arranged to generate a hydrodynamic force in the water
  • the cavity is arranged aft of the vessel’s propeller and steering devices.
  • the cavity may in one embodiment be part of a module arranged on the stern of a ship.
  • the vessel may comprise ballast tanks arranged on either lateral side of said cavity.
  • the vessel comprises a conduit having a first opening at a deck level in the vessel and a second opening inside the cavity, preferably above a nominal water line (WL) in the cavity.

  • a module 3 hereinafter also referred to as a launch-and-retrieval module.
  • the module 3 is connected to the ship afterbody 2, i.e. extending beyond the ship’s propeller and rudder 8. It should be understood that the module 3 may be retrofitted to an existing ship by attaching it to the ship’s original stern, indicated by the line S in figure 1, or it may be an integral part of the ship’s original hull.
  • the launch-and-retrieval module 3 comprises a cavity 5 generally defined by upper walls or bulkheads 6, 6a, a forward wall or bulkhead 12, and side walls 13.
  • the upper wall 6 is arranged between the ship’s main deck level HD and shelter deck level SD, but the invention shall not be limited to this configuration.
  • a bottom plate member 11 Arranged in the lower part of the cavity 5 is a bottom plate member 11, extending between the side walls 13 and extending a distance in the cavity longitudinal direction.
  • a forward (in relation to the cavity) opening 9 is thus formed between the plate member 11 and a portion 2’ of the ship’s stem.
  • a gate device 10 is arranged and configured to selectively open and close the opening 9, indicated by the double-headed arrow N in figure 2 (figures 2 and 3 illustrate a gate-open position).
  • the plate member 11 is shaped as a force-generating foil member, having a portion of increased thickness in the forward (upstream) region. But the invention shall not be limited to such shape, as the skilled person will understand that a hydrodynamic force may also be obtained by an (e.g.) flat plate member arranged an angle of attack with respect to the water flow.
  • the plate member may therefore be referred to as a hydrodynamic force member, which may be arranged to provide an upward force when the vessel is moving in the water, thus serving to lift the vessel stem.
  • the plate member may be fixed to the side walls 13 or may be movably connected to the side walls and configured to controllably rotate around a transverse axis.
  • the cavity 5 thus comprises an opening 7 which faces downwards and aft, towards, and exposed to, the water W surrounding the ship.
  • the cavity opening 7 is in the illustrated embodiment controlled by main gate device 4.
  • the main gate device 4 In figure 2 and figure 5, the main gate device 4 is in an extended position, thus defining a relatively small opening 7 in the bottom of the cavity 5.
  • the main gate device 4 In figure 3, the main gate device 4 is in a retracted position, defining a large (e.g. full) opening 7 in the bottom of the cavity and towards the back of the cavity.
  • Figure 6 illustrates how the opening 7, when fully open, extends anlong the module bottom and up into the module transom.

  • the chute opening 16 is arranged above the nominal water line WL.
  • the chute 15 is configured for deploying (setting) long-line, indicated by arrow P in figure 2.
  • the chute may also be configured for deploying protective devices (canisters) described by WO 2011/021946 Al.
  • FIG 5 which is a plan sectional view at main deck level HD in figure 2; illustrates how tanks 14 are arranged on both sides of the cavity 5.
  • the tanks 14 may be used as fuel tanks, or as pure ballast tanks having means for selectively filling and emptying (not shown).
  • the ship’s centre of gravity may thus be controlled by controlling the fluid volume inside the tanks, and the tanks may thus be used as trimming devices.
  • the main gate device 4 and the gate device 10 are normally in the full open positions, whereby the forward opening 9 is open and allows water flow into the cavity 5 and through the opening 7 which in this state is fully open, i.e. in the bottom of the cavity and towards the back of the cavity.
  • the bottom plate member 11 (which in the illustrated embodiment is foil- shaped as described above) may be configured or/and controlled to generate an appropriate trim force, depending on the external circumstances and desired operational parameters.
  • the opening 7 may be adjusted by controlling the position of the main gate 4, and/or the ballast (liquid) volume inside the tanks 14 may be controlled. It may for example be desirable to trim the ship such that the bow is raised when the ship is breaking ice or is sailing among ice floes.
  • arranging the invented module 3 on the stern portion of the ship serves to move the ship’s centre of gravity aft, which may desirable.
  • arranging the force-generating foil or plate member 11 at a lower location than that shown in the drawings may increase its efficiency. Arranging it farther aft will increase the moment arm.
  • the forward opening 9 is normally closed.
  • the long-line is not exposed to the open and does therefore not attract sea birds that otherwise might get caught on the long-line.

  • the bottom plate member 11’ extends towards the aft portion of the module, formimg the adjustable opening 7 between plate extensions 1 la, 1 lb.

  • Model tests (in towing tank) of the vessel at transit speeds (13-14 kts) have shown a pitch reduction in the aft part of the vessel of approximately 40% when the module is installed, compared to the vessel without the module.
  • Tank tests of the vessel at rest in the water (0 kts) have shown a reduction in wave height inside the cavity of appriximately 45% when the adjustable opening 7 is at its minimum, compared to the wave height at a full open state.
