The Kings Quay production hub and the associated Khaleesi, Mormont, and Samurai tiebacks remain a flagship asset in Murphy's Gulf of America portfolio nearly four years after first production. There has been continuous development activity undertaken since production startup and additional activity planned for years to come. This presentation will re-visit the strategic and philosophical approaches to subsea system design implemented for these fields, and update the technology applications and lessons learned, including production and controls infrastructure expansion and operability enhancements.
