I am not sure what these tanks hold but it looks like water (potable, grey or sewage) might be the thing.
They are across the street from a ship yard so perhaps they are destined to be installed in a vessel. I have not a clue though.
The light was shining through them in a pretty great way so it doesn’t much matter what they are for.
They take on the look of a building like the ones in the background.
I cropped the top off where the chain link fence had interrupted the photo.
It is hard to shoot a range/view finder camera through chain link fencing as you don’t see exactly what the lens sees.
