PURPOSE: To prevent the misoperations of an operator to secure the accurate switching of buttons by displaying a pump that can control the feed of LNG through a pump controller of a display means.
CONSTITUTION: The information showing the states of each LNG pump and its corresponding LNG tank are inputted to a control part G of an LNG pump control support device E via a control panel B which contains the unit number control buttons D1A to D7C corresponding to the LNG pumps. The opart G decides whether the unit number control application conditions are satisfied for each LNG pump based on those input information. Then the part G displays its decision result on a display F. Thus an operator can accurately operate the buttons D1A to D7C based on the contents of the display F. At the same time, the stable supply of natural gas is always ensured to a thermal power station at an LNG base and the burden of the operator is also reduced.
