Summary
A turbine crew yawed a nacelle without communicating with the vessel bridge, placing a blade in the ship’s intended astern path after personnel and cargo transfers. The vessel moved clear without further event. Actions strengthened communication protocols and procedural controls, requiring positive confirmation that vessels were clear before nacelle movement.
