The bases for selection were the professionalism of subject matter, depth of treatment, the importance of its contribution and its lasting technical value to the profession, the individual effort setting an example and serving as an incentive for future Naval Engineering authors, clarity of composition, style, and manner of presentation.
Mr. Wilhelmi's and Mr. Schab's paper "Glass Reinforced Plastic (GRP) Piping for Shipboard Application," which was published in the April 1977 Naval Engineers Journal. is a major contribution to the literature in the field of Naval Engineering. It not only meets all the selection criteria, but it also offers a potential method for providing a corrosion-free, lightweight, low-cost alternative to the use of metallic piping materials aboard both U.S. Navy, U.S. Coast Guard and commercial surface ships.
The need to provide improved materials for piping systems is currently a challenge, particularly as the U.S. NAVY continues to develop such advanced high performance craft as the Surface Effect Ship and the Amphibious Assault Landing Craft. Considering the weight and maintenance requirements of present-day metallic piping, the authors have presented GRP as a worthy alternative material with many potential benefits, and their paper contributes substantially to the knowledge needed to set the standards required for certifying shipboard piping materials. The potential problems, the proposed solutions, and the expressed need for developing a military specification to ensure required GRP piping characteristics for general shipboard use are expressed, and thereby encourage the ship designer to include GRP piping in ship specifications and the materials industry to develop GRP piping to meet future shipbuilding requirements. Toward this end, the authors have made a valuable and lasting contribution to the naval engineering profession and to the literature which make them both worthy to receive the 1977 "Jimmie" Hamilton Award.
