Sneak Analysis Based on Mass Flow and Its Applications in Ship Power Pipelines

Abstract

From the perspective of improving the safety and reliability of ship power pipelines, this paper proposes that the application of sneak analysis in ship power pipelines be divided into two typical situations based on mass flow and energy flow according to the design functions of each subsystem of the ship. Existing sneak analysis based on mass flow may encounter some problems such as incomplete path search and cumbersome analysis process in practical application. An improved method of sneak analysis based on mass flow is emphatically introduced. The improved method is applied in the marine desalination system and compared with the existing method. Results of the comparison show that the improve method can find new sneak problems on the basis of existing method. Thus, the improved method is feasible and effective.
