Device for salvaging a marine or submarine engine

Abstract

A device for salvaging a marine or submarine engine, this device comprising: a supple tie line ( 20 ) having a first end ( 21 ) to be connected to the engine ( 80 ), a bobbin ( 30 ) to which is connected a second end ( 22 ) of the supple tie line ( 20 ), the supple tie line being adapted to be wound around the bobbin, and a ballast charge ( 50 ) adapted to be combined with the bobbin ( 30 ). The bobbin ( 30 ) and the ballast charge ( 50 ) are such that the bobbin combined with the charge sinks, while the bobbin released from the charge floats; and the supple tie line ( 20 ) and the bobbin ( 30 ) cooperate such that the bobbin is released from the charge ( 50 ) by the unwinding of the supple tie line ( 20 ) wound around the bobbin ( 30 ).

1 . A device for salvaging a marine or submarine engine, this device comprising:
 a supple tie line having a first end to be connected to said engine,   a bobbin to which is connected a second end of the supple tie line, the supple tie line being adapted to be wound around the bobbin, and   a ballast charge adapted to be combined with the bobbin;   in which the bobbin and the ballast charge are such that the bobbin combined with said charge sinks, while the bobbin released from said charge floats; and   in which the supple tie line and the bobbin cooperate such that the bobbin is released from said charge by the unwinding of the supple tie line wound around the bobbin.   
     
     
         2 . The device of  claim 1 , wherein the supple tie line bears a first stop between its first and second ends, and wherein the device also comprises at least a first ballast element configured to slide along the supple tie line between the first end and the first stop. 
     
     
         3 . The device of  claim 1 , wherein the bobbin has a winding surface around which the supple tie line can be wound, and wherein the bobbin has a recess for receiving the ballast charge, this recess having a first opening through which the ballast charge can pass, this first opening being located on the winding surface. 
     
     
         4 . The device of  claim 3 , wherein the first opening is blocked by a first cover, the first cover having an external face defining a part of the winding surface. 
     
     
         5 . The device of  claim 4 , wherein the second end of the supple tie line is connected to an attachment point located inside the recess, wherein the supple tie line passes through the first cover, and wherein the supple tie line bears a second stop between its second end and the cover in such a way that the second stop pulls the cover so as to unblock the first opening during unwinding of the supple tie line. 
     
     
         6 . The device of  claims 3 , wherein the recess has a second opening through which the ballast charge can pass, this second opening being located outside the winding surface and being blocked by a second cover. 
     
     
         7 . The device of  claim 3 , wherein the bobbin bears at least a second ballast element, this ballast element being arranged on the bobbin so as to orient the first opening downwards, when the bobbin is under the water. 
     
     
         8 . A marine or submarine engine equipped with a device of  claim 1 , the first end of the supple tie line being connected to said engine. 
     
     
         9 . The marine or submarine engine of  claim 8 , wherein the engine is configured to take on board the bobbin enclosed by the supple tie line, the engine comprising a release system for releasing the bobbin. 
     
     
         10 . The marine or submarine engine of  claim 9 , wherein the release system is remote-controlled.
