TABLE OF CONTENTS The Mardi Gras project is one of the major new deepwater developments in the Gulf of Mexico, consisting of five deepwater prospects. It is also one of the largest and most complex offshore projects to date that has pushed the technology in several new directions. It utilizes two of the floating platform concepts discussed in Section 2.1 and has a 485 mi (780 km) pipeline transportation system, installed by the latest S -lay and J-lay technology. For these reasons, it deserves special mention in this chapter. Mardi Gras encompasses the Holstein, Mad Dog and Atlantis fields in the Green Canyon and the Na Kika and Thunder Horse fields in the southeastern Mississippi Canyon in the Gulf of Mexico. Each is owned by different partners and was developed somewhat independently between 2001 and 2006, but BP is the operator of the overall project [2.92]. The Holstein host was installed in 2004 in a water depth of 4,344 ft (1,324 m). At the time, it was the world's largest truss spar platform, with a diameter of 150 ft (45.7 m) and a height of 750 ft (229 m). The Mad Dog host is also a truss spar (128D 550H ft - 39 168 m) that was installed in 2004 in a water depth of 4,420 ft (1,347 m). The Atlantis host is a semi-submersible FPS installed in 2006 in a water depth of 7,100 ft (2,164 m). The Na...
