Elongate structure and construction/assembly method

Abstract

Apparatus and a method of providing a wind turbine (WT) are disclosed. The method comprises the steps of: at a lift position location, erecting a wind turbine portion that comprises at least one elongate tower and a nacelle member on an upper end region of the elongate tower and at least one blade member, by providing a lower tower section at the lift position location, lifting the lower tower section vertically via at least one lift support thereby providing a lifted tower section, urging at least one incoming further tower section to the lift position location, to a position under a preceding tower section, and securing a top region of the incoming further tower section to a lower region of a lifted preceding tower section; whereby lifting tower sections comprises providing tower sections, one-by-one, to the lift position location that is at a desired position proximate to at least one lift support, gripping an incoming tower section via at least one lift beam mounted on respective climber elements movable with respect to each lift support, and via the climber elements raising the gripped tower section upwards to a raised position.

Dependencies are inferred from the claim text.
