Introduction

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.
