    Motion compensating ship personnel transfer gangway - GIF

    If two of our recent GIFs (Motion compensating ship crane and Boarding a moving cargo vessel) had a child, it would be this GIF: Motion compensating ship personnel transfer gangway.

    It's interesting how this is still a one-person-at-a-time transfer.

    It is always cool to see what a simple feedback system can do given enough power. I wonder how the smaller ship senses the position of the big ship before the gangway is deployed. Maybe there are 3 targets on the big ship and distance sensors on the small ship.

    The larger vessel looks to be an FPSO The supply ship providing the crew most likely has azimuth thrusters to hold position. Connected to a DGPS system they can maintain incredible position accuracyon the high seas. About the only thing the gangway needs to do is compensate for rise and fall due to wave action.

    The old way of doing it. Transferring from the USS Rankin in 1960.

    Takes me back to childhood. Flying foxes were fun even if crossing a flooded river.
