北海越来越多地使用移动海上系统来储存石油和将石油装载到随行的油轮上。一种典型的移动装载和存储系统是铰接式浮力装载塔。本文分析了无油轮的单铰接塔在水流和规则线性波列作用力的共同作用下的运动。用拉格朗日法建立了塔架的运动方程，得到了塔架的动力响应。波浪力是使用莫里森公式的修正形式确定的，该公式考虑了水颗粒相对于结构物的相对运动。
There has been an increasing use of mobile offshore systems in the North Sea for storing and loading oil into attendant tankers. A typical type of mobile loading and storage system is the articulated buoyant loading tower. This paper analyzes the motion of a single articulated tower without a tanker under the combined action of forces resulting from current and a train of regular linear waves. The dynamic response of the tower is obtained by formulating the equations of motion by Lagrange's method. The wave forces are determined using a modified form of Morison's equation that accounts for the relative motion of the water particles with respect to the structure.
