本文报道了光滑粒子流体动力学(SPH)方法在复杂、全尺度海洋工程问题中的适用性。调查包括风力涡轮机重力基础的安装过程、从驳船下水的导管架以及螺旋桨对航道底部的冲刷。对一系列基本情况的补充验证表明，对所考虑的物理现象具有令人鼓舞的预测准确性。结果表明，SPH方法能够很好地解决流体/结构/土/土相互作用以及浮体之间的水动力相互作用等问题，对传统的网格算法提出了挑战。
The paper reports on the applicability of the Smoothed-Particle-Hydrodynamics (SPH) method to complex, full-scale marine-engineering problems. Investigations include the installation process of a gravity foundation for wind turbines, jacket launching from a barge and propeller induced scouring of the waterway bottom. Supplementary validations for a sequence of fundamental cases indicate an encouraging predictive accuracy for the considered physical phenomena. Results demonstrate that SPH is able to address the problems featuring fluid/structure/soil-interaction and the hydrodynamic interplay between several floating bodies which pose challenges to traditional mesh-based solvers.
