"Aging Oil Rigs, Pipelines Expose Gulf to Accidents"

"GALLIANO, Louisiana—On June 10, 1947, Stanolind Oil & Gas Co. won an auction for the right to drill for oil on a plot seven miles off the Louisiana coast. The company built a spindly steel platform and drilled a well in shallow waters. It struck oil, and in 1950, Stanolind sold its first Louisiana sweet crude for $2.67 a barrel.

More than 60 years later, the West Cameron 45-A platform is, according to government records, the oldest functioning platform in federal waters in the Gulf of Mexico. One of more than 100 structures built in the 1940s and 1950s still in operation, the platform has survived seven Category 2 hurricanes and a major fire.

The platform's age may have taken a toll, however.

On Dec. 4, 2009, a severely corroded pipe connecting the structure to a high-pressure gas well gave way during routine maintenance, releasing explosive natural gas into the air. Unlike most modern platforms, this one had no remote shut-off switch. Emergency valves that should have cut off the flow of gas automatically didn't close properly—in part, a subsequent investigation found, because a control panel was caked in bird droppings. Workers who had fled by boat to a nearby platform were finally able to shut down the well. "
