Atlantis PQ is a BP and BHP joint venture semi-submersible oil platform on permanent location over the Green Canyon Atlantis Oil Field in deepwater Gulf of Mexico, 190 mi south of New Orleans. The "PQ" identifies the platform as being a production facility with crew quarters.[2]
The vessel's hull was designed by GVA and built by Daewoo Shipbuilding & Marine Engineering (DSME) in Okpo, South Korea. Its topsides modules were built in Morgan City, Louisiana with hull integration in Ingleside, Texas.[3]
Operating in depths of more than 2100 m, Atlantis was the deepest moored semi-submersible platform in the world when it was installed.
