A floating door aka caisson can mean only one thing . . . 

something new is headed into the GMD graving dock.

It’s Yano . . . as in T-AKR-297.  named for Sfc. Rodney J. T. Yano.

Helping with the rotation is Resolute (starboard) and Maurania III, port stern, and

Charles D. McAllister.

Together they spin the vessel as

Freddy Miller stands by.

No dead ship is Yano, as she assists.

Tight as it looks, when the large vessel is

inside the graving dock, about 20′ margin exists on either side.

Thanks to John Watson for the first two shots;  all others by Will Van Dorp.
