When working at Rosenberg Verft in Stavanger. Norway in the 1980s I was involved with the construction of a large structure which was to become the Statfjord B platform in the North Sea. The topside structure was built on dummy concrete leg supports at the Rosenberg yard.

To give you an idea of scale, the white living quarters at the right is 7 stories high.
The height of the deck from the concrete legs to the top of the drilling derrick in the centre of the picture below was 171m, if my memory is correct.

The concrete storage cells and the four concrete legs were slip formed and subsequently outfitted at Gandsfjord also in Stavanger.

The storage cell (effectively below the water line in this shot) are 23m in diameter and 64m high; four of the 24 cells are extended by the 111m high legs.
The deck structure was mated with legs at a deep water site at Vats, before the completed platform seen below was towed out to its position in the Norwegian North Sea. The concrete cells sit on the sea bed with most of the four legs also submerged..
By comparison the barrage across the River Tees at Stockton is a much more modest affair, but impressive nevertheless.

You have seen shots of the next structure before but as it's from my local town I'll show it again.
