DEVICE FOR NOTIFYING PRESSURE INFORMATION OF A CARGO STORAGE IN AN LNG(LIQUEFIED NATURAL GAS) CARRYING SHIP, CAPABLE OF AUTOMATICALLY DETECTING PRESSURE INFORMATION ON THE VACUMM DEGREE FOR THE INSULATION LAYER OF THE CARGO STORAGE AND NOTIFYING THE PRESSURE INFORMATION IN REAL TIME

摘要

PURPOSE: A device for notifying pressure information of a cargo storage in an LNG(Liquefied Natural Gas) carrying ship is provided to efficiently manage the access control to operators by providing accurate information on the vacumm degree in an insulation layer in a cargo storage during a leakage test. The entrance control [control of access] of operator is managed efficiently.;CONSTITUTION: A device for notifying pressure information of a cargo storage in an LNG(Liquefied Natural Gas) carrying ship comprises a measuring unit(10), a controller(20) and a display unit(30). The measuring unit detects the inner pressure information of the insulation layer of the cargo storage, in real time. The controller determines the current airtightness state of the insulation layer through the pressure information provided from the measuring unit. The display unit outputs the entrance allowance into the cargo storage to the outside according to the control of the controller.;COPYRIGHT KIPO 2010
