The noise induced by centrifugal pump is one of the main concerns in the design and optimization of on-board equipment for war ships and submarines. In this work, an attempt has been made to estimate the natural frequency of onboard centrifugal pump used in ship with an ordinary conventional steel material foundation using ANSYS simulation. Further, the conventional foundation is replaced with composite material with carbon reinforcement and vibration studies are accomplished by using FE software ANSYS 20.1. The natural frequencies of centrifugal pump with steel foundation are compared with natural frequencies of centrifugal pump with composite raft foundation. It is observed that the natural frequencies are enhanced by providing composite material foundation. Weight of the overall foundation also can be reduced utilizing the proposed composite raft mount.
