A power unit for subsea use comprises an electric motor 2 driving a generator 5 inside an external pressure vessel 1 containing a gaseous atmosphere. The atmosphere may comprise air and may be at a pressure less than the ambient pressure. The motor may be an induction motor. The motor may be a DC motor and may be connected to a rectifier. The generator may be an alternator. An output converter stage that may be located within the pressure vessel 1 may provide a DC output. A remotely operated vehicle, or ROV, (10, Figure 2) with electric drive motors may be supplied with electricity by a power unit (15), which may be mounted on or in a tether management system (TMS) (11) connected to the ROV via a tether (12). The power unit may alternatively be located on or in the ROV.
