Looks pretty expendable, I doubt that this is going to be used for transporting the stage back to the shore.
No retention systems at all, which means that even small waves would result in a pretty instable situation - for helicopters for example, the first thing after landing on a ship is to secure it (often automatically), because otherwise it would move over the deck uncontrolled.
I suspect that either the rocket is supposed to be discarded after touching down as test flight or another ship is expected to rush to the barge for properly securing the stage or for lifting it on its deck for recovery.
Strange though. Securing a rocket stage after landing wouldn't be that hard if you think about the options. Even just locking the stage between some foam-protected steel cables on masts would be enough, if some possible damage to the tank structure by buckling is acceptable.
