The chapter summarizes the BP-Deepwater Horizon accident 2010 in the Mexican Gulf, which caused 11 deaths and the largest oil spill in history. The chapter builds on secondary sources and a resilience analysis is made using the theoretical framework developed in the book. It is described what the main causes of the accident were and the events that took place before, under and after the
accident. The resilience analysis clearly shows that maintaining time limits and budget was made at the expense of reliability and safety, and that unnecessary risks were taken in order to improve project economy. The end results were one of the most costly human made disasters in the history (over 50 billion USD).
