FIELD: transport.
SUBSTANCE: vibration and noise protection device for shipboard pipelines represents shock-absorbing suspension. Resilient element located between hanger and basement is made in the form of series-connected via intermediate mass pneumatic shock-absorbers of "Pneumatic shock absorbers with protection" type. Intermediate mass is made in the form of metal plate in plan view repeating dimensions of shock-absorber bottom reinforcement. Plate thickness is determined from obtaining frequency of its characteristic vibrations and on shock-absorbers attached to it, it is equal to 40÷50 Hz.
EFFECT: higher efficiency of shipboard pipeline vibration isolation.
