Abstract

The invention relates to a rotary mount (8) for a turbine (1), such as a subsea tidal stream turbine. The mount comprises a fixed part (9), and a rotary part (10) configured for connection to said turbine (1), the rotary part (10) being mounted for rotation relative to the fixed part (9). The fixed part comprises a fixed conductor (52), and the rotary part comprises rotary conductor (47), the rotary conductor (47) being electrically connected to the turbine (1) and arranged for rotation relative to the fixed conductor (52). The arrangement is configured such that electrical energy generated by the turbine (1) is transferred via the rotary conductor (47) to the fixed conductor (52) either by direct conduction, or by induction, whilst permitting rotation therebetween. In one embodiment, the mount (8) takes the form of a rotary transformer comprising a plurality of rotary conductors (47), each comprising a primary coil having a plurality of turns wound on a rotary-core (44), and a plurality of fixed conductors, each comprising a secondary coil (52) having a plurality of turns wound on a fixed-core (48), the rotary-core (44) being mounted for rotation relative to the fixed-core (48).
