A novel approach has been proposed in understanding and possible eliminating dangerous bending vibrations of high pressure fuel lines of low speed marine diesel engines. Although the theory of vibration of piping systems is rather developed today, the reasons for significant vibrations occurring in high pressure fuel pipes are not completely understood, and require thorough investigation and study. Both analytical and experimental studies performed in order to analyze dependence of diesel engines operational modes on the level of vibration and its properties. Results of numerical studies of the equation of motion of high pressure fuel pipes were obtained using Mathieu-Hill method. Those results were supplemented with data from full-scaled experiments performed on Sulzer 14RT-flex96C low speed main engine onboard of 15550 TEU container vessel Ebba Maersk. It has been proven that oscillations of the fuel in high pressure line, which take place in-between injections at the partial engine load, cause parametric bending vibration, and in some cases parametric resonance. Author has proposed a few methods in order to avoid that.
