Abstract

The paper takes the project of an offshore wind farm upper block transportation and installation as a case study. The MOSES software is used to establish the overall transport model of the transport vessel and the upper block, and to analyze the frequency domain motion response of the upper block transport process, to predict the motion and acceleration amplitude of each degree of freedom of the vessel and the upper block. The dynamic signal data of the monitoring equipment during the transportation process are collected by sensors to obtain the real-time state data of the ship and the upper block during the transportation process. After the comparison of the results, the preliminary calculation and simulation analysis are more similar to the actual monitoring data, and the reliability is high.

Key words
