Is body of water considered ground?

The floating dwelling units have to ground their system. How about a dwelling unit that is built on a permanently constructed deck that is on the body of water?

How is grounding achieved? confused

The ocean would be considered the perfect ground plane.

The actual electrode would have to be non-corrosive in salt water.

Titanium and Gold...

How do you attach to the water? How do you install an electrode?

On the comical side, this would be a true floating ground. laugh

FRom the comment of a 'dwelling unit built on a permanent deck, I would say...yes.

I gave the OP a lot of thought, as to a excersize in humor, or a serious question....& I'm still not sure.

It is a serious/curious question.

I have dealt with a few floating facilities. Answer me this, is the house affixed to the shore and is hired wired from the shore? If so then the grounding is achieved at the main on shore. See NEC 553 for more details.

If it's mobile, then it falls under different rules. NEC may or may not apply. I might be able to assist you with that

Think about the way Ships, Aircraft, or even a Space Station is "Grounded".

What would be referred to as "Ground" in these cases.
(hint: think "Automobile's Ground")
