A crane (16) for upending an elongate structure such as a monopile (28) supports elongate rigging elements that are connected to the structure at respective connection axes spaced longitudinally along the structure. At least one of those elements, of fixed length (36), extends to a first connection axis and at least one other of those elements, of variable length (34), extends to a second connection axis. A frame (24) suspended from the crane (16) supports a winch (46) that pays out the variable-length element (34) of the rigging to lengthen that element. This lowers the second connection axis relative to the first connection axis, which serves as a pivot axis about which the structure is upended.
