    Mission Power and Energy Systems in Surface Ships

    SNAME Section Meeting - External

    Sep 22, 5:30 PM - 6:45 PM (ET)
    Joint SNAME Chesapeake Section & ASNE Flagship Section Meeting


    Mission Power and Energy Systems (MPES) are fundamental to the design, mission, and operation of surface ships. MPES architecture and design are critical to determining a surface ship’s effectiveness, survivability, and cost. MPES systems are distributed systems, most simply defined as mechanical, electrical and electronic components distributed throughout a ship that are connected to work together. These systems, particularly the power and energy systems, are traditionally represented in “one-line diagrams” and “equipment lists”. Over time, distributed systems have become increasingly interconnected and interdependent, particularly in modern surface ships. This complexity makes them more vulnerable to cascading failure and to behavior that may become evident only when the system is in operation if not properly discovered and considered early. An energy flow modeling approach can provide significant insight to system design and operation while in early-stage design.


    Mark Parsons is currently a Ph.D. Candidate at the Kevin T. Crofton Department of Aerospace and Ocean Engineering, Virginia Tech. He researches network-based methods to assess surface ship distributed system vulnerability, survivability, and deactivation recoverability in concept-stage design. He received his M.S. in Ocean Engineering from Virginia Tech in 2019 and his B.S. in Naval Architecture and Marine Engineering from the University of New Orleans in 2016. Mark is a student member of SNAME and ASNE.

2019 Election Nominations

Chair - Mr. Benjamin Testerman

Mr. Benjamin Testerman is a Naval Architect in the Naval Architecture and Engineering Department of NSWC Carderock in West Bethesda, MD. During his career he has been involved in a variety of efforts including early stage ship design, vessel construction, and advanced shipboard technology development and transition efforts. Mr. Testerman graduated from Stevens Institute of Technology in 2009 with a Bachelor of Engineering and a concentration in Naval Engineering. Mr.Testerman currently serves as the Vice Chair of SNAME Chesapeake section and has held a leadership role within the section since 2011 having served as the Chesapeake Section Treasurer 2013-2018 and served as the Chesapeake Section Young Professionals Chair in the 2011 - 2012 term/

Vice Chair - Mrs. Margaret Nate
 Maggie Nate is currently a Survivability Engineer with Gibbs and Cox and has over 8 years of engineering experience.  Prior to joining G&C, Maggie had a variety of assignments in the area of ship survivability and test including  as a Senior Test Engineer supporting PMS377, the amphibious warfare program office.  She also previously worked for NASA Langley on lunar excursion module design in their Aerospace Research Summer Scholar Program and with AAI on the Shadow unmanned aerial vehicle program. Outside of work, Maggie is active in several professional societies, serving as the Associate Editor of Survivability for SNAME’s Journal of Ship Production and Design, is the Chair of the Post-Incident Safety Assurance Panel under SNAME’s Technical and Research Program, and has served as the Meetings Chair for SNAME Chesapeake Section for the past 3 years.  Maggie is a born and raised Virginian having grown up in Newport News and attended college in Blacksburg before settling in the Alexandria area.  She has degrees in Aerospace Engineering and Ocean Engineering with minors in Mathematics and Naval Engineering from Virginia Tech.  In her spare time Maggie enjoys triple integrals in spherical coordinates, attempting to teach her dog how to fetch (no such luck), and cheering on the Hokies every chance she gets.

Elected Member 2022 - Mr. Robert Ames
Bio: During his career, Bob Ames has pursued technical excellence in the field of software engineering for naval architecture and marine engineering applications.  He has significant technical achievements that are world recognized across many industries both inside and outside the marine industry. 

During his time with the Naval Surface Warfare Center – Carderock, Bob has acquired broad experience in ship and submarine platform design development, fluid dynamics, system design, computational science, computer science, cross-domain data integration, geometry, data modeling, gridding, optimization, designs of experiments, energy systems, ship arrangements, testing, model construction, computer aided design, computer numerical control, and computational validation.   

Bob is world renowned for his work in computational sciences related to multidisciplinary integration of engineering tools through theories in modeling that he developed; and one that was patented related to geometry modeling.  This patent technology is fundamental to the multi-domain integration software development framework called Leading Edge Architecture for Prototyping Systems (LEAPS).   

Through his knowledge of object oriented programming, Unified Modeling Language (UML), and System Modeling Language (SysML) development, Bob became the Navy’s pioneer in the use of ontologies for ship data modeling and continues to be the Navy’s resident expert in this field. 

Bob is also responsible for the development of two mathematics libraries, David Taylor’s Non-Uniform Rational B-Splines (DT_NURBS) and the Geometry and Engineering Mathematics Library (GEML).  DT_NURBS was developed during his days in DARPA’s Hydrodynamic Technology Center where he developed techniques for the integration of geometry, gridding and Computational Fluid Dynamics (CFD). 

Bob is currently working on system integration of power and energy technologies, systems of systems modeling, and other design science enhancements to the Navy’s early stage design tools.

When not pursuing enhancements to the Navy’s early stage design capability, Bob is a yacht designer of performance sailboats (bana.com).

Call for Executive Committee Volunteers

The Chesapeake Section is looking for new and continuing members to join our Executive Committee. If you have general interest in the direction of our Section, or a specific interest in any of our activities, contact Section Chair Tim Mierzwicki. Opportunities include assisting with the planning and conducting of Young Professional sessions, Continuing Education and Professional Development classes, T&R Panels, and other cross-organization efforts. We are looking for any and all ideas on how to improve the work of the Society and our Section.


Call for Papers

The Chesapeake Section is looking for papers for our monthly technical meetings. We invite authors to submit abstracts on topics that advance the art, science, and practice of naval architecture and marine engineering in all their applied forms including the construction and operation of ships, marine vehicles, and structures of all kinds.
