Applying CAST to investigation of the FPSO’s incident with an iceberg
On 29 March 2017, the floating production storage and offloading unit (FPSO) did not disconnect and sail away when a medium iceberg came close to the FPSO. The tow of the iceberg was unsuccessful, and the crew was instructed to brace for impact. Because of favorable weather conditions, the iceberg p...
