Summary
A walk-to-work gangway bumper broke off during an emergency-retraction demonstration while connected to an offshore wind turbine transition piece. Vessel movement during an approximately one-second uncompensated delay overloaded the bolts. Nobody was harmed. Actions included crew refamiliarisation, revised demonstration procedures and manufacturer evaluation of a possible software revision requiring class approval.

Summary
During testing to demonstrate emergency retraction, the movement of the vessel in the swell applied forces to the bumper, which caused the bolts to fail and the bumper to break off.
