Abstract
A shiplift transfer system for moving a ship between a shiplift platform and a shipyard is disclosed. The system includes transition rails coupled with the shipyard that are pivotable about trunnion pins between a position that bridges a gap between the shipyard and the shiplift platform and a position that is clear of the gap and of the shiplift platform. The pins are positioned such that the load is not transferred to the pins. Load on the transition rails is reacted at curved surfaces of the transition rails that are engaged with curved surfaces on the yard. The transition rails are accessible for maintenance and replacement via removable plates. The rails include beveling to accommodate misalignment between the yard and platform.
