Abstract：For offshore installation of jackets， subsea template guide pre-installed on seabed and sleeves designed on the jacket are beneficial to the rapid and accurate positioning of the jacket. Subsea wellheads can be pre-drilled and the development period of oil and gas field can be shortened by adopting this installation method. To investigate the interaction between jacket and guide pile during docking， MOSES software is used for the analysis of motion and impact load in time domain. The analysis results are compared with the results according to the relevant standards. The conclusions of this research have a certain reference value for the projects using subsea docking installation method.
