• weighed  27,215t (60,000,000lbs)
• water depth was 366m (1,200 ft)
• fabrication took 2,000,000 man hours 
• at the time it was the 3rd largest fixed conventional platform in the Gulf of Mexico (Bullwinkle is #1)
• the jacket is approximately the same height as the Empire State Building in New York
