Calling for entries from companies and consortia interested in undertaking a study for the OWA Logistics and O&M Technical Working Group (TWG-L) to investigate the risk of blade strikes to walk-to-work (W2W) gangways when Service Operation Vessels (SOVs) connect to offshore wind turbines. 

The main objectives of this work are to:

• Develop a blade-risk framework for W2W operations. Establish an evidence-based framework tailored to walk-to-work scenarios that defines blade hazard zones relative to vessel position and turbine state and identifies the key risk drivers and mitigation measures.
• Enable safe SOV approaches to uncontrolled or non-optimal turbines.
• Develop operational standardised procedures to remove blade strike risk during W2W gangway connection and crane operations from SOVs to the transition piece, building from existing industry knowledge and experience, building from existing industry knowledge and experience.
