海洋工程数值水池基准模型水动力特性数值模拟研究

我国正自开展数值水池自主研发研究,需要确定一代表性平台模型作为基准检验试验及数值模拟研究对象.本文针对设计的半潜平台基准检验模型建立了数值模型,进行了作业、生存和拖航三种典型工况下的水动力特性预报,获得了平台水动力系数、波浪中运动响应传递函数、关键点加速度传递函数等.将运动响应计算结果与现有第六代半潜平台的运动响应数值模拟结果进行了对比,趋势一致,验证了该模型作为基准模型具有一定的合理性和先进性.

Numerical study on the hydrodynamic characteristics for the semi-submersible standard model of Numerical Tank

The Numerical Tank project is under research, and a representative offshore platform was needed for the numerical and experimental researches. In this paper , a numerical model was created based on the designed standard model, the hydrodynamic predictions of the model under three conditions were made, the hydrodynamic coefficients, motion RAOs and acceleration RAOs are calculated. Some of the results were compared with a known semi-submersible of the sixth generation and the tends turned out to be consistent, which validates the model to be reasonable and advanced.
