Comments

The Coulomb field, is tied into the NaKika system, and at a water depth of approximately 7600 ft (2316m). Coulomb is anticipated be the world’s deepest subsea completion.  FMC is supplying the tree systems and ancillary tie-in equipment for this Subsea Alliance project.  This field is a 25-mile step out from the Na Kika HOST and is presently slated for installation and first production in the summer of 2004

These two trees broke the world record water depth for completions & likely still hold this record. Previous record was 7209' Marathon Oil, GOM, "Camden Hills".
