Summary
A walk-to-work gangway connection failed during personnel transfer to an offshore wind installation, causing minor damage and prompting the transfer to be aborted. Investigation identified reduced active motion compensation accuracy. Corrective measures addressed software parameters, annual performance verification, pre-connection stability checks and connection-point compatibility.
