A vessel with a ballast system including a plurality of ballast tanks provided with pumps for feeding water into the tanks and expelling water therefrom and an air bubbling system including underwater openings and compressors for blowing air through said openings into the water surrounding said vessel. The ballast system and the air bubbling system include a common tube system being alternatively connectable to the ballast tanks, for operating the filling and emptying of the tanks, and to the air bubbling system for conducting air to the underwater openings as described in U.S. Pat. No. 3,580,204.

1. A vessel having a hull with underwater openings, a ballast system comprising a plurality of interconnected ballast tanks with openings proximate to the bottom thereof, and means for feeding water into said tanks and for expelling the water therefrom; said ballast system being combined with a dual purpose air bubbling system for blowing compressed air to said ballast tanks to prevent ambient water from penetrating thereinto and for conducting air to said underwater openings; said air bubbling system communicating with said underwater openings in said hull; means for leading compressed air through said underwater openings into water surrounding said hull; said combined ballast system and air bubbling system being operatively associated and including a unified single common tube system alternatively connectable to said ballast tanks for emptying one of or several of said tanks by means of pumping water, and connectable to said air bubbling system for conducting air to said underwater openings, said tube system having a plurality of branches; a valve system controlling said branches of said tube system, said valve system being a remote controlled system; and means for providing power to said remote controlled system, to said pumping water means and to produce compressed air for said air bubbling system. 2. The vessel of claim 1, further including an air compressor connected to said common tube system and connectable to said ballast system and said air bubbling system to blow compressed air to said ballast tanks in said vessel as a salvage operation in case of hull rupture. 3. A vessel as claimed in claim 1, in which said common tube system includes two main tubes extending along a substantial part of the length of the vessel in said hull, said main tubes being connected or connectable to each other. 4. A vessel as claimed in claim 3, in which each of said two main tubes is connectable to serve the ballast system and the air bubbling system at one side of said vessel irrespective of the operation of the corresponding systems at the opposite side of said ship. 5. A vessel as claimed in claim 3, in which said ballast system includes at least one ballast pump having a pressure side and a suction side, said pressure side being connected to one of said main tubes and said suction side being connected to the other of said main tubes. 6. A vessel as claimed in claim 3, in which said two main tubes are interconnectable at both ends by means of a valve-controlled connection tube. 7. A vessel as claimed in claim 5, in which said pressure side of said ballast pump and said suction side of said pump are connected to both said main tubes by means of valve controlled connection tubes. 8. A vessel as claimed in claim 1, in which said common tube system comprises only one main tube extending past said ballast and air bubbling systems in the longitudinal direction of the vessel, said main tube being provided with valve controlled branch tubes connected to said ballast and air bubbling systems. 9. A vessel as claimed in claim 1, including one or several air compressors for said air bubbling system, said air compressors being connectable for operating said ballast system by providing pressure or suction in pressure and suction tubes, respectively, arranged to operate said ballast system. 10. A vessel as claimed in claim 1, wherein said common tube system is connectable to said ballast tanks for filling of said one or several tanks. 11. In a vessel adapted for moving in ice filled waters, said vessel having a hull with underwater openings, a dual purpose air bubbling system and a ballast system having a plurality of ballast tanks; said vessel including: a common tube system associated with each and alternatively connectable with said air bubbling system and said ballast system; said dual purpose air bubbling system including means for blowing air through said openings into the water surrounding the vessel after first being conveyed thereto through said common tube system and for blowing compressed air to said ballast tanks to prevent ambient water from penetrating thereinto after being conveyed to said ballast tanks through said common tube system; and said ballast system including means for feeding fluid into said tanks and means for expelling fluid from said tanks through said common tube system by means of pumping water. 12. In the vessel as claimed in claim 11, comprising a compressor having a pressure side and a suction side connected with said common tube system for blowing a compressible fluid selectively into said ballast system and said air bubbling system. 13. In the vessel as claimed in claim 12, wherein said compressible fluid is air, whereby said air when blown into said ballast tank is effective to prevent ambient water from penetrating thereinto in case of hull rupture. 14. In the vessel as claimed in claim 12 an inlet-exhaust tube for each said ballast tank for connection thereof with ambient sea water outside the vessel, means connecting the suction side of said compressor to said common tube system for aspirating water into said ballast tank through said inlet exhaust tube, and a vent with a closure valve for each of said ballast tank. 15. In the vessel as claimed in claim 11, wherein said common tube system includes a U-shaped tube arrangement having one leg of each said U-shaped tube associated with one side of the vessel, respectively, and a compressor connected with each said leg for blowing air through said common tube system. 16. In a vessel having a hull with underwater openings, a ballast system having at least two interconnected ballast tanks with openings to ambient sea through said underwater openings, and a dual purpose air bubbling system; means for feeding water into said tanks and for expelling water therefrom; said ballast system being operatively associated with said air bubbling system, and including a common tube system having a plurality of branches, said common tube system being alternatively connectable to said ballast system and to said air bubbling system; said air bubbling sstem communicating with said underwater openings in said hull; means for feeding compressed air through said common tube system to said underwater openings; said common tube system being connectable to said ballast tanks at least for emptying of one or several of said tanks by means of pumping water and being connectable to said air bubbling system for blowing compressed air to said ballast tanks to prevent ambient water from penetrating thereinto; a remotely controlled valve system controlling said branches of said tube system; and means for providing power to said remote controlled system, to said pumping water means and to produce compressed air for said air bubbling system. 17. In the vessel as claimed in claim 16, in which said tube system includes two main tubes extending along a substantial part of the length of the vessel in said hull, said main tubes being connected or connectable to each other, each of said two main tubes being connectable to serve the ballast system and the air bubbling system at one side of said vessel irrespective of the operation of the corresponding systems at the opposite side of said ship, and a ballast pump and an air compressor is provided for each of said main tubes. 18. A vessel as claimed in claim 16, in which said common tube system comprises only one main tube extending past said ballast and air bubbling systems in the longitudinal direction of the vessel, said main tube being provided with valve controlled branch tubes connected to said ballast and air bubbling systems, and one or several air compressors for said air bubbling system, said air compressors being connectable for operating said ballast system by providing pressure or suction in pressure and suction tubes, respectively, arranged to operate said ballast system. 19.
