Project: Who Dat

The Who Dat project set the standard with an extremely efficient top-notch safety execution of the Who Dat project, repaving the way major subsea projects are executed in the Gulf of Mexico.

Details that Define Success

The Who Dat oil and gas project, located in the Gulf of Mexico's Mississippi Canyon area, holds 100-300M barrels of oil equivalent, with a 30-year life. Operated by LLOG Exploration, it began production in December 2011, utilizing an Opti-Ex FPS semi-submersible on demand facility. With a focus on safety, efficiency, and efficient production operations, Who Dat represents a significant contribution to the US offshore oil and gas industry.

  • Client: LLOG
  • Location: Mississippi Canyon 547 “A”
  • Water depth: 3,100'
  • Overview: New FPU, 10K rated, 7 ea 6" Infield Flowlines, 5 ea Infield Umbilicals, 14" Oil Export and 10" Gas Export pipelines
  • Gas throughput capacity: 150,000 MMcf/d
  • Oil throughput capacity: 60,000 BOPD
  • Flowline size: 6"
  • Length: ~15,000 to 18,000'
Rick Fowler said that the “flexible” design of the OPTI-Ex facility allowed LLOG to accelerate field development. It was less than one year between the selection of the facility to field development.

Performance Metrics Speak Volumes Beyond Numbers

At the core of our success lies a powerful combination: practicality and safety.


Initial production for Who Dat was achieved in approximately 14 months from FID.


The facility was designed for a processing capability of 60,000 barrels of oil per day.

Efficiency and Safety

We prioritize safety alongside engineering and project management best practices, optimizing schedules and budgets.
