Definitions

  • the invention relates to the field of towing ships.
  • the invention relates to the towing of ships which, as a consequence of calamities, such as the failure of the main propeller, collisions or the break-out of fire on board, are no longer able to reach a harbour under their own power.
  • another vessel usually a tug, must be called for assistance to take the damaged ship under tow.
  • a tow rope must be transferred between ship and tug, which in most cases is a routine matter.
  • the aim of the invention is, to offer a solution to the above problems.
  • This aim is achieved by a combination comprising a ship or freighter such as an oil tanker or a container ship, and an installation for running out a tow rope connected to said ship or freighter, which installation comprises a floating body, which is connected to the tow rope or an auxiliary cable and is provided with propelling means, and launching means fitted on board the ship for launching the floating body from the ship, such that, after the floating body has been launched, the rope or cable can be run out with respect to the ship by means of the tensile force delivered by the propelling means of the floating body.
  • a cable can be run out to beyond the danger zone from the ship itself, without the intervention of crew present on said ship. Said cable can then be picked up by a tug at a safe distance.
  • a command to set the installation according to the invention in operation can be given in various ways. For example, if the installation is equipped with a launching device which can be actuated by a receiver, use can be made of radio signals for this purpose. The installation is then set in operation from the tug.
  • the floating body can be constructed in various ways. However, it is important that, even in heavy seas, said floating body must be able to travel in a specific line, in the direction away from the ship.
  • the floating body is therefore constructed as an auxiliary vessel which also comprises steering means.
  • the auxiliary vessel In connection with the pick-up, the auxiliary vessel carries fixing means to which a hoisting cable from a tug can be attached.
  • the floating body comprises an energy source which can supply power to the propelling means at least for a few hours.
  • the installation can keep the auxiliary cable or tow rope in the run-out position for a prolonged period. This period must be at least so long that a tug has sufficient time to sail, for example from a harbour where it is lying ready, to the stricken ship and to pick up the run-out auxiliary cable or tow rope.
  • the propelling means can comprise either a combustion engine or an electric motor, or a combination of the two.
  • the invention also relates to a ship provided with the installation described above, the launching means being installed close to the bow or the stern of the ship and pointing obliquely downwards, such that, on launching, the auxiliary vessel can be moved directly towards the water surface taking with it the auxiliary cable or the rope, which rope is attached to the ship on which the launching means are provided.
  • the launching means can be located somewhat wide of the outermost point of the bow or stern. It is also possible to install two sets of launching means, directed towards different sides of the ship, at the bow or stern.
  • the invention also relates to the use of an auxiliary vessel, which can be launched to sea and has an auxiliary cable or tow rope attached thereto, on board a ship or freighter for running out the auxiliary cable or tow rope, and keeping said cable or rope in the run-out position for a prolonged period, such that another ship, such as a tug, can take the run-out auxiliary cable or tow rope on board in order to tow the first ship.
  • a floating body which is provided with propelling means and can be launched from a platform erected in the sea is disclosed in "Ship & Boat International", Part 41, No. 1, January 1988, Worchester Park, pages 19-20, “Getting Clear”.
  • the purpose of the launched floating body is to pull a lifeboat lowered into the water from the platform away from the vicinity of said platform as quickly as possible.
  • the energy source of the propelling means is exhausted after a few minutes. Within this period the lifeboat has been towed a sufficient distance away from the platform to enable it to sail further under its own power.
  • This known installation is not suitable for running out a tow rope from a stricken ship, or for keeping the tow rope or auxiliary cable in the run-out position for a sufficiently long period such that a tug would be able to pick up the rope.
  • Said installation 2 is installed on board the ship 1, only part of which is shown in the figure.
  • Said installation 2 comprises mounting means 3, which are constructed as a tubular housing in which an auxiliary vessel 4 is housed.
  • Said auxiliary vessel 4 is secured with respect to the mounting means 3 in a known manner.
  • Said launching means comprise the rails 5, which are shown diagrammatically and extend to either side of the auxiliary vessel 4 in the mounting means 3. It is also possible to provide a drive charge, by means of which the auxiliary vessel 4 can be shot out of the mounting means 3 over the rails 5.
  • the auxiliary vessel 4 is connected to a cable 6, which is wound on a reel 7.
  • the auxiliary vessel 4 can be shot out, pulling the cable 6 with it.
  • the auxiliary vessel makes a free fall, passing through the positions indicated by 8 and 9.
  • the auxiliary vessel becomes submerged, comes up again and then floats on the surface of the water as shown at 10.
  • steering means 12 which are known per se and are also indicated diagrammatically, are provided.
  • the auxiliary vessel sails further and further away from the ship 1, until the entire cable 6 has been unwound from the reel 7.
  • the propeller device 11 of the auxiliary vessel continues to operate, so that the cable 6 is continuously held in its position, pointing away from the ship 1.
  • the auxiliary vessel is sufficiently large to carry a substantial energy source, so that such a position can be maintained over several hours. In the intervening period a tug is able to approach the auxiliary vessel 4 and pick it up by means of the fixing points 13.
  • the cable 6 can be pulled in by the tug and, where necessary, a rope located on board ship 1 can be pulled to the tug.
  • a lightweight cable is preferably used for cable 6, such that the auxiliary vessel 4 is well capable of dragging said cable 6 along over a fairly long distance from the ship. Nevertheless, cable 6 can also be made sufficiently heavy to enable it to be used itself as tow cable.
  • cable 6 is a lightweight auxiliary cable
  • a heavier tow rope can also be wound on reel 7.
  • means can be provided on reel 7 which allow the auxiliary vessel 10 to unwind the relatively lightweight auxiliary cable 6 from the reel 7.
  • Said means must then be constructed in such a way that they allow unwinding of the relatively heavy tow rope only if a traction force is exerted which is greater than the tensile force which can be exerted by the auxiliary vessel 4.
  • a higher traction force of this type can easily be exerted by a tug, such that the tow rope is released by the reel 7 only under the influence of traction force exerted by the tug.
