The U.S. Army Corps of Engineers intends to award a sole source contract to Ocean Marine Industries for the procurement of imaging sonar systems to support coastal restoration research. The requirement includes one ARIS 1800 Adaptive Resolution Imaging Sonar with specified components and accessories, plus an optional AR3 rotator package. The sole source justification is based on Ocean Marine’s exclusive ownership of patented acoustic lens and transducer technologies, which no other manufacturer is legally authorized to produce. This notice is not a request for competitive quotes, but interested parties may submit a capability statement for the government’s consideration. Any vendor seeking award must be actively registered in SAM with no active exclusions and must complete applicable FAR and DFARS representations and certifications.
