简介：作者为一个新深海的平台分析了要求，从概念的设计到水动力学分析。设计合并了允许容易的制造的深草稿多海岸警卫队女子后备队队员(DDMS)，减少了费用，并且提供了有利运动性能。它也提供了一个干燥的树系统和另外的好处。概念的设计过程包括了尺寸评价，一般安排，重量评价，重量分发，稳定性分析，等等。一个高顺序边界元素方法基于潜在的理论和修改莫里森方程被用来预言水动力学并且粘滞这个新概念平台的效果。反应振幅操作员(RAO)被获得并且与那些相比一典型捆绑海岸警卫队女子后备队队员。到3个不同极端海洋条件的JONSWAP系列的站台的反应被分析评估新概念的经得起海上风浪的能力。结果由于可得到的自由的所有度揭示了有利运动性能。
