Maintenance of ships to support operational aspects on an ongoing basis is very important from operational cycle management or life cycle management. In this case the engines on the ship, especially in the engine room which is a machine with a safety factor is quite high, so that if there is a damage can be known immediately. One type of machinery referred to here is the pump system as a single pump or groups pump. The purpose of this research is to develop a vibration monitoring system for centrifugal pumps on the ship by placing sensors on the pump. The research method was carried out experimentally by installing 6 units of accelerometer sensor connected to DAQ (Data Acquisition) and computer. The results of the study explain pump vibrations at frequencies of 24.7 Hz have been categorized as exceeding the threshold value of the natural pump frequency of 20 Hz or 1200 rpm. The value of pump vibration frequency greater than the natural frequency of the 20 Hz pump according to ISO 10816-3 standard can cause cracks in the pump system on the pump structure or pump components
