摘要

Disclosed is a support structure (1) to support offshore wind turbines. The support structure (1) comprises a foundation (2) that is configured to at least partly contact a seabed and a tower section (3). The foundation (2) and the tower section (3) are one piece. The foundation (2) comprises a narrow section (5) having a smaller diameter (9) than the maximum diameter (10) of the tower (3). A transition section (6) is located between the narrow section (5) and the tower section (3). The diameter of the transition section (6) increases from the narrow section (5) to the tower section (3).
