Summary
Three crew transfer vessel incidents concern loss of alignment at wind turbine boat landings and steering faults. Two involved near collisions with monopiles; investigations of steering failures identified worn potentiometers. Recommendations address clearing the transfer platform, stopping transfers before repositioning and considering planned maintenance or replacement of control units.
