Shchemelinin experimental determination of the forces in the anchor system of a floating object under the impact of tsunami waves
Abstract
The results of the physical modeling of interaction of long tsunami-type waves with a floating gas storage are presented in this article. It has been assumed that when transporting liquefied natural gas to Asian countries, such storage facilities will be located in the bays of the Pacific Ocean. This being a tsunami prone, the solution of the problem of determining the forces in anchor system of a floating storage regasification units at their locations from the action of possible tsunami waves is very important. The impact of a separate wave propagating under the action of one external volumetric force (gravity) on an anchored floating object located at a point with a sea depth less than the length of this wave has been considered. Evaluation of forces in anchor system with suspended blocks and devices simulating gravitational anchors under wave action has been made. The analysis of the results obtained has been carried out. Conclusions have been made about the nature of the force's variation depending on the orientation of the floating object relative to the direction of the impact of the tsunami wave and the maximum tsunami height, as well as the sea depth at the location of the anchor link.
