Abstract

A wind turbine arrangement comprises a tower 5 and at least two arms 3 projecting outwards there from. A wind turbine 1, 2 is attached to an end of each arm 3, with means being provided to selectively lower each turbine 1, 2 towards the base of the tower 5 to allow for easier maintenance. The arms 3 may be rigid with one another and pivoted to the tower 5 such that each turbine can be lowered in turn. In this arrangement two or three arms 3 and wind turbines 1, 2 may be provided. Alternatively the arms may be independent from one another and as such may both be lowered at the same time. The turbines 1, 2 may also be lowered whilst the arms 3 remain in a substantially horizontal position. A method of control is also disclosed which can align the turbines 1, 2 with the wind direction by means of blade pitch adjustment. The tower 5 may be mounted on land or at sea.
