The invention discloses an offshore wind power operation and maintenance ship heaving motion forecasting method, and relates to a new operation and maintenance ship heaving motion short-time forecasting method based on acceleration response Porny decomposition. S1, construction of heaving motion response of the operation and maintenance ship; s2, carrying out Prony decomposition on the acceleration of the heaving motion; s3, forecasting the response of the heaving motion, calculating the extreme value and the residue of the acceleration response by performing Prony decomposition on the actually measured acceleration response data, and establishing the relationship between the amplitude, the frequency, the damping and the phase of the response of the heaving motion and the extreme value and the residue of the acceleration response through the data relationship between the acceleration and the displacement of the operation and maintenance ship; and according to the response amplitude, the frequency, the damping and the phase of the heaving motion of the operation and maintenance ship, carrying out short-time forecasting on the heaving motion, and laying a research foundation of a wave compensation device of an embarkation system.
