Study on Tension Leg Platform's Motion Response by Wave Load of 2nd-order Difference Frequency Based on Intelligent Computation

The performance requirements of all kinds of intelligent computation is increasing with the 5G and big data developed rapidly. Tension Leg Platform is one of the most important marine engineering equipment, it has good motion response performance under the marine environment load. In this paper, the searching process of the modern intelligent computation algorithms are studied, the programs which could be fit for different structural calculate problems, and the wave load of 2nd-order difference frequency of a TLP with a working water depth of 400m is calculated by intelligent computation algorithms. The results show that the longitudinal displacement is close to 8m, about 2% of the water depth when the period is 30-35s, showing obvious compliance. However, it has little effect on the out-of-plane motion of TLP, which can be almost ignored.
