The Gulf of Mexico, in March 1970, was the scene of a major equipment testing and evaluation study of oil spill control and recovery equipment. The tests took place during 30 knot winds, and 8 ft waves. The oil recovery equipment tested included mechanical barriers, air barriers, and skimming equipment. A detailed report containing both the test results on the capacilities and limitations of the various equipment types tested, and also recommendations on needed improvements was prepared. It was strongly recommended that adequate skimming capacity could be installed and maintained in close proximity to all major industries which would be considered potential oil spill hazards. Recommendations were also prepared concerning the methods of enlisting community aid, both in helping to support the installation of oil spill recovery equipment, and also in working to clean up such spills as do occur.
