| Abstract: | Accidents of fixed derricks of the floating crane often occur in the seaway. According to practical requirements the authors of this paper have studied the dynamic response of derricks under the action of waves and presented a mechanical model and a calculating method based on the new knowledge of fluid mechanics and solid mechanics. The aim of this paper is to find a proper way to consider the dynamic responses under the action of waves when floation cranes are designed. |
