===Deepest platforms by type===
This is a list of oil wells based on the depth of the water in which they were drilled. It doesn't include how deep underground they go, which in some cases is over 10,000 metres.

===Other metrics===
The [[Hibernia Gravity Base Structure|Hibernia]] platform in [[Canada]] is the world's  heaviest offshore platform, located on the [[Jeanne D'Arc Basin]], in the [[Atlantic Ocean]] off the coast of [[Newfoundland and Labrador|Newfoundland]]. This ''[[gravity base structure]]'' (GBS), which sits on the ocean floor, is {{convert|111|m|ft}} high and has storage capacity for {{convert|1.3|Moilbbl|m3}} of crude oil in its {{convert|85|m|ft|adj=on}} high caisson. The platform acts as a small concrete island with serrated outer edges designed to withstand the impact of an [[iceberg]]. The GBS contains production storage tanks and the remainder of the void space is filled with ballast with the entire structure weighing in at 1.2&nbsp;million [[ton]]s.

[[Royal Dutch Shell]] has developed the first [[FLNG|Floating Liquefied Natural Gas (FLNG)]] facility, which is situated approximately 200&nbsp;km off the coast of [[Western Australia]]. It is the largest floating offshore facility. It is approximately 488m long and 74m wide with [[Displacement (ship)|displacement]] of around 600,000t when fully ballasted.
