An optimal operation of compressors used onboard vessels for various purposes is very important. In this study, the drawbacks of conventional air compressors are addressed. Interruption of the operations by unpredictable electrical power blackout and corrosion are the key drawbacks. The corrosion occurs due to a manual drain, which depletes the life of the air tank, thereby causing damages to the compressors. To address this challenge, the need for modification of conventional air compressors is imperative. Hence, this study entails the design and fabrication of an air compressor system with rechargeable characteristics, well equipped with an automatic drain sensor and pressure switch, to obtain optimal system efficiency and reliability. From the obtained results of the test and performance of the compressor, it is obvious that it is efficient and reliable for onboard ship operations.
