Definitions

• the present invention concerns a securing/deploying sys ⁇ tem for towing cables/lines for vessels.
• the towing point (“strong ⁇ point”) of the ship is located externally, internally in connection with the ship's hull or to the existing se ⁇ curing point (“strongpoint”) , and wherein one end of the towing cable/line/wire is passed via a loop from the towing point to a dispenser device, e.g. a drum on the vessel .
• Fig. 1 shows the device according to the invention in an activated condition
• Fig. 2 shows the device according to the invention i a storage position
• Fig. 3 shows the device according to the invention in a semi-extended position of a towing cable/line
• Fig. 4 shows the device according to the invention at full extension of a towing cable/line
• Fig. 5 shows the towing cable/line at full extension wherein the cable/line is being secured to a towing tug ⁇ boat.
• the towing system ac ⁇ cording to the present invention comprises a main towing cable/line/wire 1 running from a storage device, e.g. a drum 2, and which at a second point on the cable/li ⁇ ne/wire 1, e.g. at its other end 3, is secured at its end securing point, e.g. with a shackle, to a main securing point ("strongpoint") for the vessel 5 so that there between the storage device 2 and the main securing point 4, before extending the cable/line/wire 1, is created a loop 6.
• the loop 6 is the point of the cable/line/wire 1 being the capture point for the cable/line/wire, and which is extended when the cable/line/wire 1 is used.
• the cable/line/wire 1 will run out from the stor ⁇ age/deployment device 2 until it has reached its full extension.
• the one end of the cable/line/wire 1 which is not fastened to the securing point of the vessel ("strongpoint") runs freely so that the cable/line/wire 1 at its full extension has this end outside the ship 5.
• the cable/line/wire 1 may preferably at its free end be equipped with an end loop 7 to be fastened e.g. on a towing tugboat to a towing vessel 8.
• the capture loop 6 of the cab ⁇ le/line/wire 1 is equipped with a capture device 9, e.g. a roller, clamp, shoe, etc.
• a capture device 9 e.g. a roller, clamp, shoe, etc.
• a collecting line 10 which may ease the actual capturing of the main cable/line/wire 1.
• a signalling device and/or a floatation device e.g. a capture buoy with a light signalling device (flashing light) and/or sound signalling device (bullhorn) 11.
• the capture/towing sequence for the depicted embodiment of the towing cable/line/wire will be as follows:
• the towing cable/line/wire 1 will in a storing condition be coiled onto the drum 2 with a permanent fastening for its one end in the towing point ("strongpoint") 5 of the ship 5, and it will is passed through a hawse 12 (see fig. 2) .
• the other end of the towing cable/line/wire is formed as a loop 6.
• the buoy with the light signal being connected to the capture line 10 When the ship is in distress the buoy with the light signal being connected to the capture line 10 will be thrown overboard to be captured by a rescue or towing vessel 8.
• the loop 6 of the cable/line/wire 1 When extending the capture line 10, the loop 6 of the cable/line/wire 1 will become steadily larger (see figs. 1 and 3) until the loose end of the cable/line/wire passes through the aperture of the hawse 12.
• the free end of the cable/line/wire 1 being equipped with an ex ⁇ tended par, e.g. a shackle, loop, knot etc., has a diame ⁇ ter at its extended end which is small enough to pass through the roller 9.
• the towing cable/li ⁇ ne/wire 1 When collecting the capture line 10 the towing cable/li ⁇ ne/wire 1 will accordingly be passed completely from the deployment device 2 and will in a completely extended position stop against the roller 9.
• the roller 9 may be equipped with opening devices so that it may be released of the cable/line/wire , or it may be kept on the cab ⁇ le/line/wire as such.
• the end loop 7 may be placed over a convenient puller in the towing tugboat 8 , or it may be secured to especial towing equipment on the tugboat 8.
• the towing cable/line/wire 1 may also be equipped with devices (not shown) tightening possible slacks and pre ⁇ venting jerks in the cable.
• Such devices may be of a conventional type, e.g. such devices which are based on a spring-arrangement.
