随着海洋工程技术的迅猛发展，海洋平台向着大型化、集成化方向发展，这也对海上安装技术提出了更高的要求，浮托安装技术在此背景下应运而生。针对浮托系统进行充分的研究，对平台海上安装的设计和实施具有重要意义。本文介绍了工业界和学术界研究人员对浮托安装系统的数值和试验建模与分析，包括水动力分析、载荷缓冲装置的建模以及主要的进船和载荷转移阶段的非稳态非线性多体系统的研究现状。为浮托系统的数值和试验建模提供了详细参考，同时对未来的发展趋势给出见解。

With the rapid development of offshore engineering technology， offshore platforms are developing towards large-scale and integrated， which also puts forward higher requirements for offshore installation technology， and floatover installation technology also comes into being under this background. It is of great significance for the design and implementation of offshore platform installation to carry out sufficient research on the floatover system. This paper introduces the numerical and experimental modeling and analysis of the floatover system， including the hydrodynamic analysis， the modeling of the load buffer device， and the research of the nonstationary nonlinear multi-body system. Some views on future development trends are also provided.
