OHMSETT is the only facility where full-scale oil spill response equipment testing, research, and training can be conducted in a marine environment. The Ohmsett test tank allows testing of full-scale equipment. The tank`s wave generator creates realistic sea environments, while state-of-the-art data collection and video systems record test results. Our facility has proven to be ideal for testing equipment, evaluating acquisition options, and validating research findings. Government agencies, academia, 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, and to conduct training with actual oil spill response technologies. The development of standard tests over the years that also led to ASTM standards is the biggest asset. These are repeatable and accepted worldwide.

Ohmsett is located at the Naval Weapons Station Earle Waterfront in scenic Leonardo, New Jersey (approximately one hour south of New York City).  Ohmsett's above ground concrete test tank is one of the largest of its kind,  measuring 203 meters long by 20 meters wide by 2.4 meters deep. The tank is
filled with 2.6 million gallons of crystal clear saltwater.

Features & Capabilities

  • A main towing bridge capable of towing test equipment at speeds up to 6.5 knots

Through a variety of mechanical, electrical, and chemical systems at Ohmsett, the following test parameters can be controlled or measured:

  • Sea state (wave height, length, and period)
  • Tow speed
  • Meteorological data
  • Water temperature and salinity
  • Volume of oil encountered and recovered by test equipment or protocol
  • Oil-water ratios
  • Physical characteristics of experimental oil
  • Behavior of treated oils


A summary of activities conducted at Ohmsett has been compiled to provide a comprehensive overview of the capabilities of the Bureau of Safety and Environmental Enforcement's (BSEE) Ohmsett Facility.

It is designed as a general information database and reference for managers, scientists, engineers, technical specialists, spill responders and the general public who have an interest in understanding oil spill response technology and current progress in improving this technology.
