Abstract

Abstract: A mooring system usually contains a tether and a mooring body. The motion equation of mooring system should be developed to research the kinematic parameters of the mooring system under the effect of wave. Based on the Newton’s Second Law, a governing equation of tether is established. Moreover a discrete motion equation of tether is deduced through the lumped mass method. According to the momentum and angular momentum theories of rigid body, a longitudinal motion equation of the rotary mooring body is developed. The mooring body model and the tether model constitute the longitudinal motion equation of mooring system together with the added corresponding boundary equation. In the end, the simulation example is simulated by using the 4th order RungeKutta method. The results show that the mooring system periodically sways under the effect of wave.

Key words: maritime engineering and technology, tether, mooring system, wave, motion simulation
