Current Zumwalt Class destroyers (DDG 1000) sea chest openings are unique because they must be flush to the hull, limiting implementation of common sea chest designs (e.g., bubble shields or raised inlets). This design results in the ingestion of higher amounts of ice, debris, and air, resulting in increased maintenance costs, potential pump failure, and degraded overall cooling performance. The Navy desires a drop-in addition to the sea chest system on the DDG 1000 destroyers that will mitigate seawater system air and debris internally. Mainstream proposes to develop a production-ready, engineering-qualified dual-stage integrated cyclone (DSIC) prototype that meets Navy shipboard requirements for the sea chest water management system (SCWMS). We will develop biofouling abatement capabilities, address waste ejection overboard (i.e., eductor design), fabricate a full-scale prototype system, and experimentally demonstrate performance. Mainstream will partner with Florida Institute of Technology, a highly regarding university with a leading Oceanography and Ocean Engineering program equipped with state-of-the-air static and dynamic seawater test facilities at Port Canaveral, two research boats, and active research grants with the Office of Naval Research and the shipping and coatings industries. Florida Tech will support the project with biofouling control design and system testing.
