Looks like a piece of burst drillpipe (size reference is the T handle in the right of the pic) sticking out of the seabed.
The rig was using a Top Drive System, not a kelly.[/QUOTE]
Second look: Judging from the look of the tear the metal looks to be very thin. It’s well corroded inside.
The more I look the more I can convince myself it does look square and it’s not the lighting effect.
The rig definately had a TDS, so my guess is this is some conduit from the rig somewhere. Square is strange though.
