Abstract
A windmill construction (10), comprising a rotor-nacelle assembly (12) with blades (14), a tower (16), a substructure (20) and a foundation (22). The substructure (20) comprises a first guide collar (24) and a second guide collar (26) for support of the tower (16), said first guide collar (24) being located in a lower part of the substructure (20) and said second guide collar (26) being located in an upper part of the substructure (20). The substructure (20) comprises a jack-up assembly (30) for receipt of modular tower segments (18), said tower segments (18) are arranged to be assembled in the substructure (20) and erectable by the jack-up assembly (30) to produce an assembled tower (16). The invention is also directed to a method for assembly of a windmill construction.
