Analysis on sway of spilled oil recovery apparatus lifted up from unmanned surface vehicle

This paper discusses the sway of a spilled oil recovery apparatus mounted on the unmanned surface vehicle (USV) when it is lifted up off water surface. The dynamic model is established considering the pitch of the USV, and simulation experiment is conducted under the condition of no wind disturbance. The results show that the amplitude and frequency of the pitch are main factors influencing the sway of the oil recovery apparatus, and the effect of rope length on the sway is much smaller than amplitude and frequency of the pitch.
