Abstract: This paper investigated the floatover installation process on a jacket with numerical and experimental analysis. Numerical analyses in both frequency and time domain were carried out for typical configurations during floatover operation. Corresponding model tests were also performed in ocean engineering basin. The comparison between numerical and experimental results shows that the response amplitude operator and time series agree quite well. The barge has favorable hydrodynamic behavior in considered sea state and the loads of equipments are allowable. The floatover operation on the jacket is feasible.

Key words: floatover, jacket, offshore installation, topside
