Features of experimental research of the tsunami waves impact on a floating object with an anchor system

Abstract

The article examines the features of the methodology for conducting experiments on physical modeling of the process of long tsunami-type waves impact on a floating object and analyzes their results. It is assumed that when transporting liquefied natural gas to Asian countries, such storage facilities will be located in the bays of the Pacific Ocean. The specified transport corridor may be exposed to tsunami waves. Solving problems related to ensuring the safe operation of offshore facilities under the action of various types of external loads at their location is highly relevant and has practical significance. The paper examines the features of modeling the tsunami wave impact on hydraulic structures and presents a detailed description of the experimental setup with an analysis of its features. The main attention is paid to the methodology of conducting experimental works using sensors and an information system for measuring various quantities. Analysis of the experimental results indicates not only the need to measure the forces in the connections of the anchor system, but also the necessity of determining the movements of the floating object when it is exposed to a tsunami wave. Conclusions are drawn about the prospects of using ultrasonic sensors, as well as the need to consider the reflection of waves from the basin walls and take measures to eliminate or reduce the effects of waves reflected from the walls on the object under study.
