The present invention relates to a temperature and pressure monitoring system of a sealed derrick structure, wherein temperature and pressure of the sealed derrick structure are monitored to recognize whether the temperature and the pressure of the sealed derrick structure are abnormal, thereby making it possible to effectively respond to hazards. The invention, which is a temperature and pressure monitoring system of a sealed derrick structure that is communicated with a moon pool, comprises: one or more temperature sensors which are installed inside a sealed derrick, and monitor the inside temperature thereof; one or more pressure sensors which are installed inside said moon pool, and monitor inside pressure differences thereof; and one or more damping units which are installed on one side of said sealed derrick in order to overcome abnormal changes in the inside temperature of said sealed derrick and abnormal changes in the inside pressure of said moon pool, and induce or discharge the ...
