The behavior of the tank vertical supports of Independent Prismatic Tank System of Liquified Gas Carrier is very important because the supports are the main members which transfer the tank movements to hull structure and vice versa. Measurements of reaction force of tank vertical supports were carried out during tank test condition and actual voyage of about 2 years. in cooperation with Nippon Kaiji Kyokai by 80,000m^3 LPG carrier which was constructed in November 1980 by IHI. The results were compared with analytical values and following conclusions are obtained. 1) The accuracy of analytical method applied to tank design is confirmed to be sufficient. 2) The assumed phase lag of internal and external pressure is within acceptable range and the design maximum value of supporting forces have sufficient margin against the maximum pressure estimated by measurement.
