Offshore platforms of the world

87 iconic installations by basin: where the saturation diver actually works. Operator, type and depth.

Why they matter

Saturation diving exists because of these structures: fixed platforms, semi-submersibles, spars, TLPs and FPSOs anchored, at times, in more than 2,000 m of water. Their construction, inspection and underwater maintenance is the industry's work. From the legendary Piper Alpha (a milestone in offshore safety) to the Troll A Norwegian one (the largest structure ever moved), here are the most iconic. 7 have already been decommissioned.
