IMCA’s Renewable Energy Workgroup and the National Workboat Association (NWA) have been seeking a consensus on the optimum design and configuration of boat landings for accessing wind turbine foundations from crew transfer vessels (CTV).
The resulting publication ‘Standardised boat landing research report’ (IMCA SEL 041/ M 232) has been released by IMCA. In order to undertake this task, a questionnaire was issued to all the operators of European offshore wind farms to gather information on existing boat landing geometries. At the same time, feedback was sought on the experience of CTV operators, fender manufacturers and structure designers. On analysis of the data it has been possible to develop a recommended geometry for a standard boat landing that is consistent with the G+ Global Offshore Wind Health & Safety Organisation (formerly G9) guidelines.The document includes sections on crew transfer to offshore wind turbines; the questionnaire; data analysis; fender impact loading, safe clearances; as well as the executive summary, introduction, conclusion and recommendations.
