Ohmsett's above-ground concrete test tank is one of the largest in North America, measuring 203 meters long by 20 meters wide by 2.4 meters deep and filled with 10 million liters of saltwater. The wave generator creates variety of sea states, while modern data collection and video systems record real-time test results. Our facility has proven to be ideal for testing full-scale equipment, evaluating acquisition options, and validating research findings.

Government agencies, academia, and public and private companies use Ohmsett as a research center to test oil spill containment/clean-up equipment and techniques, to test new designs in response equipment, to conduct training with actual oil spill response technologies, and to explore the capabilities of wave energy devices in a near-real-world open ocean environment.
