ASNE is the leading professional engineering society for engineers, scientists and allied professionals who conceive, design, develop, test, construct, outfit, operate and maintain complex naval and maritime ships, submarines and aircraft and their associated systems and subsystems.  ASNE also serves the educators who train the professionals, researchers who develop related technology, and students who are preparing for the profession.  Society activities provide support for the U.S. Navy; U.S. Coast Guard; U.S. Marine Corps; U.S. Merchant Marine and U.S. Army.

ASNE is the seventh oldest technical society in the United States.  It was founded in 1888 by a group of naval engineering pioneers, most of them officers of the U.S. Navy's Engineering Corps, who sought a unified approach to their profession in order to make the most of new advances in technology. The purposes of ASNE are:           

  • to advance the knowledge and practice of naval engineering in public and private applications and operations,
  • to enhance the professionalism and well-being of members, and
  • to promote naval engineering as a career field.

For 125 years, the Society’s objectives have been strengthened and preserved to meet the changing needs of a time-honored profession. Today ASNE conducts a variety of technical meetings and symposia, publishes the highly regarded Naval Engineers Journal and a number of other technical proceedings and publications, and fosters professional development and technical information exchange through technical committees, local section activities and cooperative efforts with government organizations and other professional societies.

The Society's annual meeting, ASNE Day, is typically held in February of each year in the Washington, DC, area. The meeting features major addresses by high level industry and government leaders and panel discussions by leading members of the profession.  It also includes presentation and discussion of technical papers on a variety of timely naval engineering topics, presentation of the Society's prestigious annual awards and a large exposition with government and industry exhibits covering the full spectrum of naval engineering technology. ASNE Day is highlighted by the Society’s annual Honors Gala, attended by hundreds of executives and senior managers from both government and industry.

Our website is designed to not only serve our members, but also to support scholars, students and others interested in the varied field of naval engineering.  We welcome your suggestions on ways we can improve your experience.

For the best original paper published in the Naval Engineers Journal during the year 2007 as set forth in the following:

The paper “High-Speed Generators for Power-Dense, Medium-Power, Gas Turbine Generator Sets” was published in the 

Naval Engineers Journal, Spring 2007, Volume 119, Number 2 edition. The authors have done an outstanding job in addressing electric plant generator options as part of an overall system optimization across multiple attributes, as well as presenting and discussing the individual technologies and their shipboard implementation in this exceptional technical paper.

The authors identify, develop, and evaluate several concepts to improve turbine generator set power density. Their evaluation focuses on the turbine generator set as a part of overall system optimization, with weight and volume penalties for special auxiliaries. Power density is given priority, while other attributes such as efficiency, acoustics, and total system cost are also assessed. The strengths and weaknesses of each concept are assessed based on technical viability, potential for power density improvement, and risk.

The authors investigated sixty-one generator concepts over four generator types and evaluated them using three different ship-level electrical distribution architectures. They conclude that integrated power systems designed to utilize direct-driven high-speed technology enable system weight improvements independent of the generator technology selected. Further, high temperature superconducting, permanent magnet, and water-cooled wound field technologies are all possible concept alternatives, and the selection of a particular configuration yields significant trade-offs in compatibility with shipboard applications, tactical operational availability, developmental and programmatic risk, and cost.

The authors’ explanation of the fundamental technologies is clearly written and well-presented in graphical forms. They clearly have a superior knowledge of the subject matter and have explained it so that a wide audience can benefit from the results of the study. They are indeed highly deserving of the Society’s 2007 “Jimmie” Hamilton Award.
