Abstract: The invention relates to a transportation system for a wind turbine component such as a wind turbine nacelle or a section of a tubular wind turbine tower, said system comprising a wind turbine component with a rigid structure. The system further comprises at least one standardization means directly or indirectly connected to the rigid structure (6) of said wind turbine component (3), where said at least one standardization means defines a space enclosing said component. The invention also relates to a vehicle for a transportation system, a displacement system and a method of establishing a transportation or displacement system for a wind turbine component.

Abstract: A smoke chamber for a fireplace comprising both inclined (23, 24, 27, 28) and vertical (21, 22, 25, 26) supporting elements, each element having abutment surfaces (51) and supporting surfaces (34, 44) of such shape that a significant part of the load on the inclined elements is converted into a substantially vertical load on the vertical elements. The element built smoke chamber mounted on a burning chamber is immediately upon positioning capable of supporting a heavy brick chimney.
