World Renowned Propeller Expert To Retire
After a career leading the modernization of U.S. ship and submarine technology, Dr. William B. Morgan, Head of the Carderock Division's Hydromechanics Directorate, is retiring December 30th with almost fifty years of service. During his career, the Iowa native brought computers into naval engineering, revolutionizing propeller design by shifting from empirical to theoretical, becoming the first in the world to put the theoretical propeller data into a computer. This dramatically reduced propeller noise, enhancing submarine and ship acoustic characteristics. For example, he and his associates developed the highly skewed propeller with its superior vibration and acoustic properties. His largely unheralded work helped the United States win the Cold War.

Maritime Surveys Ltd., Shoreham, Sussex, U.K., recently took delivery of the first SeaBat 8160 multibeam echosounder system from RESON A/S. The SeaBat 8160 was installed on one of Maritime's survey vessels, the Scotian Shore. Alastair MacDonald, managing director of Maritime Surveys, commented on the success of the sea trials: "The SeaBat 8160 delivered the highest quality multibeam survey data in a swath width of 1,300 meters at 3,000 meters water depth, even when experiencing a near 20 degree roll and 12 degree pitch. The excellent data quality combined with the system's portability makes the 8160 extremely valuable for our operations." During these trials the system was supported by GSE Rentals of Aberdeen who supplied a TSS POS M/V 320 system.
Navy Lab Engineers Honored
Dr. Stuart D. Jessup has been named Senior Research Scientist in Hydromechanics for the United States Navy. Dr. Jessup, a mechanical engineer, works at the Naval Surface Warfare Center Carderock Division (NSWCCD) Hydromechanics Directorate in Bethesda. Jessup's contributions to the science and naval engineering of marine propellers has earned Navy and international recognition. Most recently, he received the Navy Meritorious Civilian Service Award. He has lead the development of new propeller blade design methods that replace the use of standardized blade sections with custom designed section shapes tailored to each specific application. Recently, he developed technology for suppressing tip vortex cavitation inception by unique shaping of the propeller blade tip geometry.
