USS TRIPOLI (LPH 10) UNDERWAY VIBRATION TRIALS

Abstract

An underway vibration trial of USS TRIPOLI (LPH 10) was conducted with measurements concentrated on the mast and island structure, the hospital area, the hull, and the main propulsion system. Data were analyzed to determine the nature and cause of excessive vibrations in the mast and island structure and in the hospital area at high ship speeds during free route (straight course) and maneuvering operation. The results of the underway trial are evaluated with data obtained during an earlier vibration generator survey of the mast- island structure and hospital area of TRIPOLI and compared with measurements obtained during an underway trial on USS OKINAWA (LPH 3) conducted in March 1963. The results of the various tests are used as a basis for recommendations in order to mitigate the excessive vibrations of TRIPOLI and for further effort required for correction of the LPH class vibration problems.
