Abstract: Provided is a flange for connecting to a complementary flange, and wherein the flange includes a first flange-segment and a second flange-segment, wherein a) the first flange-segment includes a primary bolt circle including an annular arrangement of inclined openings; and a first annular connection face adapted to lie against a complementary second annular connection face of the second flange-segment; and b) the second flange-segment includes on two opposite sides annular connection faces adapted to lie against complementary annular connection faces; a primary aperture circle including an annular arrangement of openings; and a second body section with a secondary bolt circle including an annular arrangement of openings. Also provided is respective flange-segments, a method for manufacturing such flange and a tower construction.

Abstract: Provided is a coupling assembly for connecting a tower or a transition piece of a wind turbine to a monopile including a first coupling part configured to be connected to the monopile and a second coupling part configured to be connected to the first coupling part. Further provided is a tower end of a tower of a wind turbine connected to a second coupling part of the coupling assembly. Finally, a method of driving a monopile of a wind turbine into the ground, a top end of the monopile being connected to a first coupling part of the coupling assembly is also provided.

Abstract: Provided is a coupling assembly of a wind turbine including a first coupling part and a second coupling part, the first coupling part and the second coupling part being configured to be coupled with each other, the first coupling part including a first surface with a first insertion hole being configured to be inserted by a fastener, the second coupling part including a second surface with a second insertion hole being configured to be inserted by the fastener, the first surface being configured to abut the second surface.

Abstract: Provided is a stud system for connecting a first flange to a second flange of a tower, the flanges including arrangements of openings in the first flange corresponding to arrangements of threaded blind openings in the second flange, with a predefined opening-length and a predefined opening-diameter of the openings in the first flange and a predefined non-threaded length and a predefined threaded length of the threaded blind openings in the second flange, the stud system including: a stud bolt with a head end, a threaded end and an intermediate portion, and a spacer tube partly encompassing the stud bolt with an outer diameter bigger than the predefined opening-diameter, wherein the stud bolt includes stopping means at the head end, preventing the spacer tube from slipping over the head end. The spacer tube) constructed such that it can be removed laterally from the stud bolt.

Abstract: Provided is a flange for connecting to a complementary flange, and wherein the flange includes a first flange-segment and a second flange-segment, wherein a) the first flange-segment includes a primary bolt circle including an annular arrangement of inclined openings; and a first annular connection face adapted to lie against a complementary second annular connection face of the second flange-segment; and b) the second flange-segment includes on two opposite sides annular connection faces adapted to lie against complementary annular connection faces; a primary aperture circle including an annular arrangement of openings; and a second body section with a secondary bolt circle including an annular arrangement of openings. Also provided is respective flange-segments, a method for manufacturing such flange and a tower construction.
