The basis for this selection was made on the professionalism of the subject matter; depth of treatment; the importance of the contribution with respect to its lasting value to the profession; individual effort which would serve as an incentive and encouragement to future Naval Engineering authors; and finally on the clarity of the composition, style and manner of presentation.
LT Silva's paper "Welding Processes in the Deep Ocean," which appeared in the August 1968 issue of the Naval Engineers Journal, represents a major contribution to the naval engineering field. It not only fulfills all of the selection criteria but it helps to expand the knowledge of naval engineers in an area which is becoming of increasing importance. This paper makes available in a concentrated yet digestible form a wealth of information on the techniques and problems of joining metals underwater. The history and theory of gas and electric welding and cutting are blended together with a practical understanding of the difficulties involved in the performance of work in the ocean. LT Silva has thoroughly documented his conclusions relative to our current capabilities in this critical area of ocean engineering and has logically developed his recommendations for extending these capabilities to greater oceanic depths.
LT Silva's achievement in presenting this timely dissertation to the naval engineering profession makes him well qualified to receive the 1968 "Jimmie" Hamilton Award.
