On local stress distributions in impact‐loaded Offshore Steel Substructures

open access: yesce/papers, Volume 9, Issue 2-3, Page 2826-2830, September 2026.
Abstract The global energy transition necessitates a significant expansion of offshore wind energy. To ensure long‐term operational efficiency, offshore wind turbines (OWT) require regular maintenance by specialized crews. The crew is transferred via Crew Transfer Vessels (CTV), which land at the boat landing, generating substantial impact loads.
