The present disclosure relates to a tower sheet assembly, a tower section, and a tower transportation and assembly method. The tower sheet assembly comprises a tower sheet, and a foldable platform, which is arranged on an inner side of the tower sheet. The foldable platform comprises a platform main body and a support member. The support member comprises a support seat, wherein a first end of the support seat is fixed to an inner wall of the tower sheet, and a second end of the support seat is hinged to the platform main body at a first hinge point, such that the platform main body can pivot, around the second end of the support seat, between a folded position and an unfolded position.

A pipe securing system for modular heavy-duty vehicles includes at least one support beam and at least one bearing device that is arranged on the support beam in the bearing state and next to the support beam in the resting state. A method for supporting a pipe on a modular heavy-duty is also provided. The pipe securing system and the method provide a space-saving system that dispenses with external lifting equipment, such as forklifts or cranes, and can be used both in a production hall and outside in the open.

A transport structure (42) for transporting a set of wind turbine components (22) on a vehicle (92, 94). The transport structure (42) comprises: a support structure (44), comprising at least one frame (46); and a set of locking interfaces arranged on the support structure (44) for releasably securing the transport structure (42) when in transit. Said at least one frame (46) comprises attachment means configured for releasably securing at least one wind turbine component (22) of the set of wind turbine components to said at least one frame (46).

A method for installing a wind turbine tower is provided, wherein the tower includes a tower fastening portion and a tower through hole in the tower fastening portion, including: providing a vessel with a vessel fastening portion and a vessel through hole in the vessel fastening portion, landing the tower onto the vessel with the tower through hole at the vessel through hole, positioning a stud in the tower through hole and the vessel through hole, wherein the stud includes an upper portion protruding from the tower through hole in an upward direction and a lower portion protruding from the vessel through hole in a downward direction, fastening the tower fastening portion to the vessel fastening portion by a lower fastening element attached to the lower portion and an upper fastening element attached to the upper portion, wherein the lower fastening element and the upper fastening element are both detachable from the stud in a non-destructive way.
