Thunder Horse is the largest semi-submersible production, drilling, and quarters platform in the world. Designed to withstand Category 5 hurricanes, it typically houses a crew of about 200.
Thunder Horse PDQ was evacuated with the approach of Hurricane Dennis in July 2005. After the hurricane passed, the platform fell into a 20~30 degree list and was in danger of foundering.
