Disclosed is a power generation, distribution, and on-board power supply system for low-emission surface marine (navy) ships of different classes and sizes. The system is embodied as an equipment segment and includes at least one cruising speed drive unit, which can be supplied with electrical power from a DC network, and at least one auxiliary drive unit, e.g. a hydrojet, which can be supplied with electrical power from an AC network and can be connected as required. The DC network and the AC network are configured in such a way that power can be mutually transferred.

Provided is an amphibious vehicle such that the deterioration of a fuel economy ratio due to driving at a low load ratio can be suppressed. The amphibious vehicle can travel on land, sea, and waterfront and is provided with: a gas turbine; an electric generator to which output from the gas turbine is transmitted via a first clutch; a water propeller to which the output from the gas turbine is transmitted via a second clutch; a storage battery that is charged with or discharges electric power produced by the electric generator; a motor rotated and driven by electric power supplied from the storage battery; a wheel rotated and driven by rotation and driving of the motor; and a control apparatus that controls the above units. When travelling on land, the control apparatus causes electric power to be supplied from the storage battery to the motor so that a front wheel is rotated and driven by the motor.

A marine-(navy) or commercial or yacht ship-type equipment system is for electrically driven ships having different sizes and driving power. The ships, as well as coast guard boats and customs boats, include standardized equipment segments for the propulsion and operation thereof. The individual equipment system for ship types consists of hulls, which are embodied according to the type of ship, i.e. are made according to size and specific task requirements and the equipment segments for propulsion, such as electrical oar propellers and waterjets, and for the operation of the ship such as the energy generator, the energy distributor and automation elements, are embodied according to type and according to driving power and function of the individual ships. The equipment segments are embodied in a prefabricated manner and can be installed on different areas in the hull of the ship.

A marine reduction gear makes it possible to reduce the installation space of an electrical rotating machine. A marine reduction gear includes: an input shaft coupled to an output shaft of an engine; an output shaft coupled to a propeller shaft that rotates a screw propeller; a gearbox accommodating an input gear provided on the input shaft and an output gear provided on the output shaft, the gearbox supporting a first bearing that supports the output shaft in a rotatable manner; and an electrical rotating machine including: a central shaft that rotates together with the output shaft; a rotor fixed to the central shaft; and a stator surrounding the rotor. The gearbox supports the stator and a second bearing that supports the central shaft of the electrical rotating machine in a rotatable manner.
