军事海上基地行动包括将船只系泊在近海，并在它们之间转移货物和设备。一个新开发的环境和船舶运动预报系统（ESMF）将通过提供船舶在波浪中的运动预测来促进这些操作。通过对环境波的遥感，并将这些波作为预测船舶运动模拟的输入，提供了船舶运动的连贯预报。为支持ESMF系统而开发的关键技术包括：定制的波感雷达；一种最小二乘逆波检索算法船舶快速耐波性模拟的运动模型以及健壮的点对点系统架构。ESMF系统在R/V Melville上的演示中进行了广泛的测试，结果非常好，通常在30分钟的间隔内实现预测与实现信号的相关性优于80%。ASME版权所有©2015
Military sea basing operations include mooring ships together offshore and transferring cargo and equipment between them. A newly developed Environmental and Ship Motion Forecasting (ESMF) System will facilitate these operations by providing predictions of ship motions in waves. Coherent forecasts of the ship motions are provided through remote sensing of the ambient waves and using these waves as input to a predictive ship motion simulation. Key technologies developed in support of the ESMF system include: a custom-built wave sensing radar; a least squares inverse wave retrieval algorithm; a ship motion model for performing rapid seakeeping simulations; and a robust peer-to-peer system architecture. The ESMF system was tested extensively in a demonstration aboard the R/V Melville with very good results, often achieving correlations of forecast-to-realized signals of better than 80% over 30 minute intervals.Copyright © 2015 by ASME
