Nothing then happens really for 8 days. The tugs move around a bit, visit the western piers occasionally.

Fast forward to the 17th and at 0539 UTC the tugs are back at the same boat, with Bo Tuo likely tied up to it.
They start to drag the sub back across, getting half way at 0621 UTC, 1 to 1.5 kts speed

And are back in there at 0710 UTC.

The tugs then hang around the gates, probably whilst they close them up.
Note: some of the spurious routes are poor GPS coverage.
