Green Ship

CEM is investigating technologies to help ship owners operate their fleets in a more fuel-efficient, reliable manner which is synergistic with a global push for lower-emission marine transportation.  With private funding, we have conducted a number of engineering studies. Our research began with the evaluation of ship propulsion systems, which resulted in fuel savings and reliability improvements through optimized granularity of the diesel generator set.  To facilitate the development of technologies for further fuel efficiency, a study was completed to quantify the annual fuel consumption associated with typical, major electrical ship loads.  This then led to studies of the benefits of leading edge HVAC technologies, efficient lighting including LED, novel hull shapes and low-drag coatings, advanced motor/generators using superconducting technologies, the use of alternative fuels and renewable energy sources, and others.

Our research, although not funded by the Navy, supports the Navy’s envisioned "Great Green Fleet", with less dependence on fossil fuels, more use of alternative fuels, and enhanced efficiency.  Success by the Navy will help it achieve its mission while reducing both fuel cost and the effects of the uncertainty of international fossil fuel sources.

Additional studies have been completed and will be available soon.  These include ship lighting, air cavity ship technology, hull coatings, wind power, roll stabilization, superconductivity, and photovoltaics.
