Does anyone know what this object by Saunders Ness Road is?

Purely a guess, but since it is opposite Greenwich, is it marking the
prime meridian on the north side of the river?

That's a good thought, but it's not exactly north of the observatory.

There are various items scattered around the area from the old docks. If
this wasn't part of a buoy, it may have marked the entrance lock to one of
the docks.
