The present invention relates to a control system for preventing water hammering of a jack-up barge and, more particularly, to a control system for preventing the water hammering phenomenon of a jack-up barge, which is configured so that the actual control of a valve controlled by a control signal of the control system is actually controlled after a delay of a predetermined time after the control signal is recieved, in order to prevent a water hammering phenomenon occuring by the action of the valve opposite to the hydraulic supply when a jack-up system of the jack-up barge is controlled.
본 발명은 잭업바지선의 워터해머링 현상을 방지하기 위한 제어시스템에 관한 것이다. 구체적으로는, 잭업바지선의 잭업시스템을 제어할 때 유압 공급의 반대되는 밸브의 작용으로 발생되는 워터해머링(수격현상)을 방지할 수 있도록, 제어시스템의 제어신호에 의해 제어되는 밸브의 실제 제어가, 제어신호 수신 후 일정시간 딜레이 된 후 실제 제어되도록 구성된, 잭업바지선의 워터해머링 현상을 방지하기 위한 제어시스템에 관한 것이다.
