Description
Hurricane Ivan caused massive landslides that destroyed parts of the offshore oil & gas infrastructure along the front of the Mississippi River Delta. This talk summarizes the geologic processes that created this failure-susceptible seafloor, and how failures are triggered by interactions between the seafloor and shoaling storm waves. The discussion includes an overview of methods that have been used to reduce the risk of damage to production platforms and pipelines from seafloor movements beneath a structure, or from mudflows that cross the region and encounter the facility.
