In order to optimize the seawater frequency conversion system,this paper compared 3 energy sav-ing modes to analyze the difficulties in the design of the frequency conversion energy saving system of seawater pumps and optimize the frequency conversion control logic.Meanwhile,this paper used the software"pipenet"to opti-mize the piping system design and determine the actual working point of the seawater pump.In addition,it calcu-lates the actual energy-saving effect of the seawater pump according to the working point of the pump.Finally,based on the energy-saving effect,this paper analyzed the rationality of pump selection in the early design stage,which provides valuable experience for other similar marine engineering project design and construction.
