Project Scope:

  • EDC was engaged to perform engine vibration measurements on a clients Patrol Boat to investigate high vibration at high rpm.
  • Measurements included acceleration and displacement measurements.


  • Capturing both low frequency data from ocean induced vibration, and high frequency data from engine firing vibration simultaneously.


  •  The low and high frequency engine vibrations were captured for the full rpm range.
  • The natural frequencies of the engine were captured and provided input to finding a solution.
