ABSTRACT:
The present invention provides a self-contained propulsion apparatus1suitable for a sub-sea ROV. The apparatus comprises:a reactor vessel2having at least one inlet3, 4and an exhaust7;reservoirs10, 11for holding fuel and an oxidant material therefor, wherein the reaction products of said fuel and oxidant comprise steam; a remotely operable fuel and oxidant supply control device12, 13; and a steam turbine9connected to the exhaust7so as to be driven by steam from the reactor vessel2. The turbine9is drivingly connected39to a propulsion device42for propelling the ROV in use thereof. A degassing apparatus17is provided for substantially removing steam and any other gas phase reaction products, from the gas phase into the liquid and/or solid phase, downstream of the turbine9.
