T-903-G – Electric Ships – An Exciting Future for the ...

1 Mari-Tech 2012 Exhibition and Conference Re-birth of the Marine Technical Community T-903-G Electric Ships An Exciting Future for the Young Professional Gene Joelson, CD1 Business Development, Naval, Marine, Offshore GE Energy Biography Gene Joelson has extensive experience as a Marine Engineer and Naval Architect with a number of years at sea in senior engineering positions in the Ships and submarines of the RCN. He holds advance degrees in engineering and business and since leaving the RCN in 1996 has worked primarily in the aerospace, defence, and marine industries. Gene joined Converteam, now GE Energy power conversion , in 2008 and is responsible for the development of power conversion s business marine business in Canada.

2 He is based in Burlington, Ontario and works closely with power conversion s technology centres in Pittsburgh, Rugby England and Belfort France. Gene travels throughout Canada to bring power conversion s leading technology in Electric ship propulsion and integrated platform management systems to the Canadian market place. Description The re-birth of the marine technical community in Canada presents many new challenges to the young engineers who choose to pursue a career in marine industries. Where once young propulsion system engineers learned the fundamentals of steam technology, now they will be challenged to learn the fundamentals of Electric propulsion. Where once young engineers learned the fundamentals of Bailey analogue controls systems, now they must learn about programmable logic controllers and microprocessors running real time operating systems in a dual redundant Ethernet arrangement with supervisory control and data acquisition applications and highly ergonomic human machine interfaces.

3 The renewal of Canada s federal fleet has the potential to evolve the RCN into an Electric Navy and is introducing state of the art power electronics and modern rotating machines to the Canadian Coast Guard. Programs to acquire new ferries are bringing Electric propulsion to those provinces. Commercial shipping companies in Canada are moving toward Electric propulsion for Ships with suitable operating profiles. 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.

4 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.
