Mari-Tech 2012 Exhibition and Conference – Re-birth of the Marine Technical Community
This presentation is aimed at the young professionals entering Canada’s marine industry. It will highlight some of the key technologies incorporated in modern integrated electric power and propulsion plants and illustrate application of the technology in recent ship projects for government and industry in various countries. It is hoped that the presentation will serve to motivate the young professional to consider how they can become tomorrow’s electric propulsion specialists to meet the growing demand in Canada for that special expertise.
