The mudslide area of the Gulf of Mexico - where the Mississippi River meets the Gulf - is home to enormous platforms. When this area was developed, the instability of the seabed necessitated construction of structures capable of withstanding this shifting floor environment.
Built in 1978, the South Pass 78A platform was one of these imposing structures. A monstrous four-pile, straight-leg platform, it was located just 12 miles (19 km) south of the mouth of the Mississippi River in approximately 230 ft (70 m) of water.
