The invention belongs to the technical field of ocean engineering, and particularly discloses a simulation method for long-distance towing of an offshore floating structure, which comprises the following steps: S1, acquiring environmental parameters and towing parameters to form an input matrix M; s2, solving a wave load, an ocean current load and a sea wind load according to elements in the input matrix M; s3, calculating the tension of the tow rope according to the tow rope model; and S4, substituting the load parameters calculated in the steps S2 and S3 into the six-degree-of-freedom time domain motion equation, and solving to obtain the motion information of the tugboat and the floating structure in the whole towing process. According to the method, the nonlinear influence caused by the navigational speed is considered for solving the wave load and the hydrodynamic coefficient; by inputting the matrix M, an input module considering the environmental parameter change under the large space and time scale in
