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 2003 as set forth in the following:

The paper "Reliability Assessment of Corroding Ship Hull Structure" was published in the Naval Engineers Journal, Fall 2003 edition. The authors have developed an approach for time-dependent reliability assessment of the ultimate strength of a ship hull structure in the presence of corrosion. By modeling corrosion growth as a time-dependent random function and using the second order reliability method to calculate the instantaneous reliability of the primary hull structure, they demonstrated that the proposed time-dependent reliability is always lower than the instantaneous reliability and more sensitive to the statistical value of the corrosion parameters than their probabilistic distribution descriptions. Time-dependent reliability results provide the basis for computing hazard functions and subsequent decisions relating to life expectancy analysis and extension. 

The authors have demonstrated the proposed method using a typical cross section of a tanker including parametric analysis. 

This paper captures the essence of time-dependent reliability-based analysis of ship structures subject to corrosion, and provides a basis for including corrosion in reliability studies in order to obtain realistic estimates. It is definitely in keeping with the technical standards of the Naval Engineers Journal. The authors are most deserving of the Society's 2003 "Jimmie" Hamilton Award.
