Progress in Naval Machinery during the Last Thirty Years

Abstract

The problems and aims of Naval engineering have remained remarkably constant during the last 30 years, but requirements dictated by military developments have had an increasing effect not only upon machinery design, but also upon the design of the ship as a whole. The manner and conditions in which our ships must be operated have also changed considerably during this period, calling for additional equipment to make living conditions more tolerable. These changes have required not only the solution of complex design and development problems, but also the development of high standards of manufacture and installation, and the development of efficient organizations for maintenance and spare gear. It is safe to say that the demands made on Naval machinery will become even more exacting, and we can never afford to relax our efforts in striving for perfection in the engineering of our machinery designs.
