At the Deepwater Technical Symposium, MMA Gulf of America Region Director Bryan Domangue highlighted how better data, engineering and technology are expanding what’s possible offshore.

From 200 psi to 1,500 psi to 20,000 psi, advances in technical understanding and deepwater technology continue to push the boundaries on energy development.

“Somebody in this room is already working on what comes next.”

Operated by the U.S. Department of the Interior’s Marine Minerals Administration, Ohmsett features a 2.6-million-gallon saltwater wave tank that simulates ocean conditions for scientific testing.

API recently hosted a chemical dispersant demonstration at Ohmsett that educated stakeholders on the tactics and science behind this important oil spill response tool for safeguarding marine ecosystems.

When oil spills, dispersants can be used to break slicks into smaller droplets for "oil-eating" microbes to digest. OR&R recently joined experts at New Jersey's Ohmsett facility to test this alternative response technique under real ocean conditions. https://t.co/TPlZSd8Gar
