Impact


Gulf of Mexico

This was the first hurricane to cause significant disruption to oil refining in the Gulf of Mexico. Several hundred active wells went out of service, and drilling came to a halt for a few days during and after the cyclone's passage. One of Humble company's tenders saw three-quarters of its mooring chains compromised, which swung it around into an adjacent oil platform, causing $200,000 in damage (1956 USD). The cost to downtime in production was greater than the damage Flossy created to the oil rigs.Benfield Corporate Risk
