Adding a flange plate to a curved surface.

I'm trying to work out how to get a raised circular flange effect on a 2 way curved surface. I can get the Project Curve bit to show, and can extrude that, but it's only the sidewalls. I can't get it to become solid. Planar won't work on the curved circle either.

Probably an easy one, but I'm stumped!

Thanks!
