The Model Test of Ice Forces

Since the rapid development of the offshore petroleum exploitation in the Bohai Gulf, the ice model test has become more important in the design of structure of platforms located in the ice infested water. In the first part of the papet, a general review of the ice model test technique is given briefly . The second part of the paper introduces the model test of sea ice forces on a monopod ice resistant platformin the Liaodong Bay . It was carried out in the first ice model tank in the country,which was completed and started operation in 19&7 at the Tianjin University . The introduction includes the facilities,the model ice technology and some of the test results, including the failure modes of ice sheet in front of the structure , the maximum values and time variations of the ice forces and their characteristic frequencies . The test results are compared to both the field observation and theoretical analysis, and some comments are presented.
