Biography

Timothy McCoy has over 35 years of experience in the design, construction and operation of ships and their power and energy systems. Prior to joining the Faculty at the University of Michigan, he worked as a marine engineering consultant in the areas of power and propulsion systems, control systems and ship design and construction. Previously, he served as the civilian director of the US Navy’s Electric Ship’s Office in Washington, DC where he oversaw the development of electric power and propulsion systems for the US Navy’s fleet. Before entering government service, he worked in industry as R&D Director and President of a global power systems company where he conducted a research and development program for the marine, steel, renewables and oil and gas industries. He served for 22 years on active duty in the US Navy as an engineering duty officer. His military experience includes the development of shipboard electric power and propulsion systems, control systems and the design and construction of several classes of Navy ships. He has taught ship design and systems engineering courses while on the faculty at MIT and has conducted original research on a variety of naval architecture and marine engineering-related topics. Dr. McCoy is a registered Professional Engineer, an IEEE Fellow and a member of ASNE, ABYC and SNAME. He has published over 50 technical papers.

Research Interests

Autonomous Shipboard Systems. There has been much recent interest in autonomous unmanned ships and boats. Nearly all of the research to date has been focused on the advances in sensing and control required to facilitate the vessel’s movement and safe navigation. Little effort has been focused on the numerous shipboard systems that would also need to operate in an autonomous mode in order to make these autonomous ships feasible. Advances in system resiliency, self-healing characteristics, machinery self-diagnostics and prognostics will be required for the Hull, Mechanical and Electrical plant to operate for the duration of a voyage or mission without human support. These advances are prerequisites for the viability of future autonomous ships.

Marine Power and Energy Systems. Development of new ways to improve overall system efficiency through the use of energy storage, waste energy recovery, advanced cycle engines and novel system architectures are key to meeting the world’s transportation needs in a sustainable manner. More electric architectures, including both hybrid electromechanical propulsion, integrated electric propulsion and the use of large format electrochemical energy storage are enabling technologies for meeting emerging requirements for both commercial and military ships. Design tools are needed for these new component technologies and more electric architectures that enable system optimization during the design phase. Advanced control methods are also needed to optimize the operation of these systems to maximize system performance, minimize both exhaust emissions and operating costs
