Abstract
Turning gear apparatus for rotating a shaft comprises a rotary drive arrangement and a transmission system including a pivot arm. The rotary drive arrangement is fixed, for example to a vessel hull, and the pivot arm is pivotable between a first, shaft-disengaged, position and a second, shaft-engaged position where the rotary drive arrangement is operably coupled to the shaft, thereby permitting control over rotation of the shaft by the rotary drive arrangement.
