One of the enduring images of the catastrophic damage that last summer’s hurricanes inflicted on Gulf Coast oil and gas production facilities was the picture to the left of Royal Dutch Shell PLC’s MARS floating production platform (previous posts here and here), which was badly damaged by Hurricane Katrina. As this Washington Post article reports, Shell has finished repairing the huge platform, just in time for this year’s hurricane season. The article goes on to provide a handy overview of the importance of the Gulf Coast oil and gas infrastructure for meeting the nation’s energy needs and the efforts to bolster the ability of that infrastructure to weather the severe storms of hurricane season.
Despite the massive repairs, the main improvement in the MARS platform to protect it from another severe storm is decidedly low-tech — stronger and twice as many clamps to hold the drilling rig to the platform. Those clamps work against vertical and horizontal forces and, during Katrina’s category 4-5 winds (the storm hit shore as a strong cat 3 storm), three inch steel bolts holding the previous clamps were sheared straight through. Although the old clamps had survived many storms, Shell engineers believe that the new ones will work even better.
