Abstract

A local-analytic-based Navier-Stokes solver has been employed in conjunction with a compound ocean structure motion analysis program for time-domain simulation of passing ship effects induced by multiple post-Panamax class ships in the exact condition of a real waterway. The exact seabed bathymetry was reproduced to the utmost precision attainable using the NOAA geophysical database for Virginia Beach, NOAA nautical charts for Hampton Roads and Norfolk harbor, and echo sounding data for the navigation channel and waterfront facilities. A parametric study consists of 112 simulation cases with various combinations of ship lanes, ship speeds, ship heading (inbound or outbound), channel depths, drift angles, and passing ship coupling (in head-on or overtaking encounters) were carried out for two waterfront facilities at NAVSTA Norfolk and Craney Island Fuel Terminal. The present paper provides detailed parametric study results at both locations to investigate the site-specific passing ship effects on the motion responses of ships moored at nearby piers.

多艘系泊船舶过船效应的CFD研究

采用基于局部解析的Navier-Stokes解算器，结合复合海洋结构运动分析程序，对在真实航道的精确条件下多艘超巴拿马型船舶的过船效应进行了时域模拟。利用美国国家海洋和大气管理局(NOAA)弗吉尼亚海滩的地球物理数据库、汉普顿路和诺福克港的NOAA海图，以及航道和海滨设施的回声探测数据，精确地再现了海底测深数据，达到了最高的精度。对NAVSTA诺福克和Craney岛燃料码头的两个滨水设施进行了参数化研究，包括112个模拟案例，包括船舶航道、船速、船舶航向(入港或出港)、航道深度、漂移角和过往船舶耦合(迎面或超车)的各种组合。本文提供了两个地点的详细参数研究结果，以研究特定地点的过船对停泊在附近码头的船舶运动响应的影响。
