| Abstract: | The vibration responses of floating drilling vessels in random sea waves are studied in this paper by using the theory of random vibrations.On the basis of analysis of previous mechanical models,a multi degree model with a distributed mass is established.The dynamic responses of the system are obtained by using the spectral analysis method.Furthermore,the computational formulae are given for dynamic loads of hook,heave compensation system and derrick.This work provides theoretical support for fatigue strength and fatigue life analysis of the system. |
