摘要

为了测量非冲击波对垂直穿刺筒的载荷作用，在法国马赛中央学院(ECM) 17 m长波槽中进行了试验。研究了两种聚焦波的不同圆柱体结构(截面和长度的形状和大小)。用莫里森方程计算的波浪荷载与实测结果进行了比较。本文的背景是浮式结构上LNG储罐泵塔晃动引起的水动力载荷的评估。如果将莫里森方程与相关的液体速度和加速度的时间序列相结合，则在所有研究情况下的比较结果都是好的。

Assessment of the Morison Equation for Nonimpacting Wave Loads on a Vertical Cylinder

Tests are performed in the 17 m long wave tank of Ecole Centrale Marseille (ECM) in order to measure the loads induced by nonimpacting waves on a vertical piercing cylinder. Different configurations of the cylinder (shape and size of the section and length) are studied for two focusing waves. Wave loads as calculated by Morison equation are compared to measurements. The context is the assessment of the hydrodynamic loads due to sloshing on the pump tower in LNG tanks on floating structures. The comparisons turn out to be good in all cases studied provided Morison equation is used with relevant time series of liquid velocities and accelerations.

期刊介绍： The primary aim of the IJOPE is to serve engineers and researchers worldwide by disseminating technical information of permanent interest in the fields of offshore, ocean, polar energy/resources and materials engineering. The IJOPE is the principal periodical of The International Society of Offshore and Polar Engineers (ISOPE), which is very active in the dissemination of technical information and organization of symposia and conferences in these fields throughout the world. Theoretical, experimental and engineering research papers are welcome. Brief reports of research results or outstanding engineering achievements of likely interest to readers will be published in the Technical Notes format.
