Two U.S. Navy ships, along with Bahraini Coast Guard emergency management teams, participated in a proof-of-concept demonstration April 29 off the port of Mina Salman. USS McCampbell (DDG 85) and USNS Catawba (T-ATF 168) executed the proof of concept, which entailed simulating an oil spill and conducting the subsequent containment and recovery. During the demonstration, McCampell Sailors simulated the shipboard responses to an oil spill, including launching rigid-hull inflatable boats, assembling a hose team and using hazardous material (HAZMAT) apparatus, while Catawba Sailors launched an offshore boom (floating barrier) intended to contain a large spill at sea.
