A method for moving an object on the bottom of a body of water comprising producing a positive buoyancy in the region of one of the supports of the object to lift the support from the bottom of the body of water and then turning the object in the desired direction around another of the supports which remains at rest on the bottom of the body of water. Upon completion of the turning movement of the object, the raised support is lowered by producing a negative buoyancy in the region of such support. The positive and negative buoyancy is produced by means of gas and water pumped into containers mounted in the region of the supports.
A method for moving an object on the bottom of a body of water, said method comprising formig hollow members at opposite ends of the object, providing a total negative buoyancy in said hollow members to cause the object to rest on the bottom of the body of water via spaced supports on the object, producing a positive buoyancy in one of the hollow members to raise the associated end of the object above the bottom of the body of water, turning the object around the other said support to orient the object in a given direction, producing a negative buoyancy in said one hollow member to lower said associated end of the object until the object now again rests on both supports on the bottom of the body of water.
A machine for travel on the bottom of a body of water, said machine comprising a frame, first and second spaced supports respectively pivotably connected to said frame to turn in at least two planes, first and second container means on said frame in the region of each support, means for introducing a working medium into each said container means for selectively producing positive and negative buoyancy such that forces can be applied to the frame to lift and lower the associated support from and onto the bottom of the body of water, and means for turning the frame about one support while the other support is raised above the bottom of the body of water.
A machine as claimed in claim 9 wherein said container means comprises inner and outer shells defining an intermediate space, said means for introducing working medium into the container means being connected to said intermediate space.
