The influences of those factors, such as mooring line condition, fender arrangement, dolphin arrangement, degree of ship loading, long period wave, direction of wave, and wind upon the impact energy of the mooring ship have been studied by experiments and analysis. Based on the systematic test data, a semiempirical formula has been developed to calculate the impact energy of the mooring ship to the berthing facilities under the action of regular waves. It was shown by experiment that this...

In the present paper, the resonant response of a vertical mooring-line in case of neutrally buoyancy, for a given harmonic longitudinal excitation, is discussed.

Sea wave motion response oi a single point moored tanker float ing production system is the prerequisite for determining the efficiency of a tanker-mounted oil gas separator. Firstly, a mechanical model was established to derive the differential equations describing its movements. Then, the forces on the tanker were analyzed by "strip theory" used in naval architecture. Inertial force, damping force, restoring force resulting from static hydraulic pressure and wave force corresponding to surge, heave, pitch were evaluated. The determination of the mooring forces on the tanker is the key to analyzing the motion response. By means of the theory of similarity, a model test was performed to determine the relation between the tension and elongation of the mooring line. A function of the tension and elastic elongation of the mooring line was obtained by polynomial regression. Then the mooring forces on the tanker could be determined. At last, taking a 11870 oil tanker converted floating production system as a example, the solution of the differential equations was obtained. A scaled model test gave identical results with the theoretical analysis.

确定单点系泊船形浮动采油装置在海浪中的运动响应是确定装于其上的油气分离器分离效率的前提。本文通过简化、得到了单点系泊船形浮动采油装置的力学模型,在此基础上,导出了其运动微分方程式。根据船舶工程中常用的“切片理论”对油轮进行了受力分析,求得了它在纵荡、升沉、纵摇时所受到的相应的惯性力、阻尼力、静水压力引起的恢复力、波浪力。根据相似理论,采用模型试验的方法测得了锚链的张力—拉伸关系,及其函数关系式,从而算出了油轮所受到的锚链系泊力。最后,以一艘十一万八千吨油轮改装的船形浮动采油装置为例,对运动微分方程式进行了求解。为了检验理论分析的结果,以上述装置为原型,进行了单点系泊船形浮动采油装置的模型试验,试验结果和理论分析结果吻合较好。
