reduced in submarine main power, auxiliary power, weapons, and off-board vehicles.
The Panel on Platforms was asked to examine how technology can be utilized to ameliorate the environmental impact of future naval platforms, and in so doing put specific emphasis on shipboard waste treatment systems to minimize water pollution. The panel decided to treat the reduction of air emissions as a component of advanced propulsion system development for both naval vessels and aircraft. Current (mature) technologies for shipboard waste treatment such as plastics processors, pulpers or shredders, and liquid filtration systems, which have long enjoyed development under the auspices of Navy laboratories, are already at the implementation stage in many larger vessel classes. The enabling technologies considered, including supercritical water oxidation, advanced incineration, and plasma arc pyrolysis, have differing benefits and constraints in terms of power requirements, weight and space, efficiency, operator expertise required, and signature implications. Moreover, the reliability of treatment systems, particularly a single treatment system, seriously affects the suitability of the system for shipboard implementation. As a consequence, a series of smaller-scale, waste stream-specific technologies (including plastics processors, incinerators, and liquid filtration systems), which can be driven by existing energy sources (e.g., JP-5 or diesel fuel), is recommended for future development and implementation, in contrast to larger-scale, energy-intensive devices such as the plasma-based systems.
It is the conclusion of this panel that the shipboard waste treatment systems for future warships should be designed for easy implementation into the platform. Power requirements must not necessitate external shipboard generators and the associated increase in space required.
In conclusion, the panel believes that there are many technologies available to the Department of the Navy for future platform design and implementation options. These opportunities, if pursued in an integrated and systematic way, will allow decision-makers of the future to make choices based on changing requirements and affordability constraints.
