(from the editorial board ) January 2012 The Gulf of Mexico (GOM) is a major source of U.S. oil and natural gas, producing approx- imately 29% of the nation?s oil. e rst GOM oshore oil discovery was made 75 years ago, in 10 ft. of water, approximately a mile from the Louisiana shore. Today, more than 75% of GOM oil and gas production is in water depths greater than 1,000 ft. World records for exploration and production water depths continue to be set, with the recent Perdido production platform installation in 8,000 ft. water depth, including the deepest subsea com- pletion at 9,627 ft. below the surface. e oshore petroleum industry directly employs more than 55,000 U.S. workers in the GOM, with many more dependent on this vital economic sector. To support this indus- try, the Gulf Coast is home to numerous oil and gas explo- ration companies, as well as shipbuilding and ship repair facilities. The 80-plus ship- yards located there build vessels for the U.S. govern- ment, commercial owners, and the recreational market, themes that will be explored throughout this issue of (mt) .Bollinger Shipyards is one of those facilities, and is the subject of our feature, ?e Parent Craft Model.? In December, the third United States Coast Guard fast response cutter was launched, the design of which was based on a Damen parent craft. And in our Professional Development department, we prole the workforce training and development program of one of the nation?s biggest and busiest shipyards, Ingalls Shipbuilding. Our cover features the Atlantis deepwater oating production semisubmersible, one of 43 oating oil and/or gas production systems in the GOM. ?Going Deep? provides perspective on the evolution of oshore energy production from the earliest days in the industry to the advanced oating production units in use today. And you can learn more about safety aboard these facilities in our Policy Brieng section, which focuses on coast guard inspection activi- ties on the outer continental shelf in the wake of the Deepwater Horizon incident. Our Vessel Report explores the design process and challenges of building a 191 ft. super- yacht, recently delivered by Trinity Yachts in Gulfport, Mississippi. Carpe Diem is the eleventh-largest yacht ever to be built in the United States. ere?s much more, including a look at the William B. Morgan Large Cavitation Channel in Memphis, Tennessee, as well as MT Notes entries on mooring, damage stability calculations, and friction stir welding. And if you?re a seafood fan, don?t miss our GOM restaurant review in the Travel section, inspired by Coastal Living magazine?s ranking of the best seafood dives. Despite the negative press from the oil spill in 2010, the GOM continues to prove its resil- ience in the face of disaster. We hope this issue of (mt) oers enlightening reading about this key player in the maritime industry. Vicky Dlugokecki and Rod Allan SNAME (mt) Editorial Board America?s ?Third Coast?
