Abstract

In this paper, an analysis of various components of ship submersible pumps such as impeller, motor, mechanical seals, thrust bearing, electrical cable, housing, shaft, pressure sensing instrument and variable speed drive are carried out. Marine submersible pump related accidents and various causes of failure of the submersible pump mechanical seals are discussed, including pump vibration, dry running of the pump, temperature (higher), unsuitable start up procedures and wear and tear in maritime environment. Also, regulations governing safety of machineries onboard vessels are discussed.
