Abstract: When reversing a marine power plant, due consideration must be given to the fact that the inertia of the ship will continue to force the ship through the water during a moment of time after the shut down of the prime mover, with the propeller then acting as a water turbine tending to rotate the propeller shaft in the same direction as before. If the propulsion plant includes a gas turbine and a reversing gear, the reversing gear is designed in such a manner that the part thereof connected to the turbine will represent, in use, a smaller inertia than the part connected to the propeller shaft, with the propeller shaft together with the propeller attached thereto representing a considerable rotating body.
Abstract: A composite barge-tug vessel is provided which comprises a detachable tug and barge which when brought into full engagement form an integrated vessel capable of use on the high seas.
