摘要

本文描述了一个高保真的数值模型,用于模拟船舶在富冰水域的停泊作业。离散事件模拟引擎包含了几个新功能,包括新的船头和船中部浮冰破坏模型;促进浮冰漂流的浮冰形成策略;考虑到物理限制的船舶推进器模型,如推进器角回转率和螺旋桨倾斜率。它适用于各种冰场规格,并在标准台式个人计算机(英特尔®酷睿™i7处理器或同等产品)上实时运行。该模型已在几种破冰条件下使用通用钻井船模型的物理测量进行了验证;它预测了推进器的力量和运动,与在动态定位操作中观察到的情况相当。

Discrete event simulation of vessel stationkeeping operations in ice-rich waters
This paper describes a high-fidelity numerical model that simulates vessel stationkeeping operations in ice-rich waters. The discrete event simulation engine incorporates several novel features, including new ice floe failure models for bow and midships locations; an ice floe creation strategy that facilitates rafting of ice floes; and a vessel thruster model that takes into account physical limitations such as thruster angle slew rates and propeller ramp rates. It accommodates a wide range of ice field specifications and runs in real-time on a standard desktop personal computer (Intel® Core™ i7 Processor or equivalent). The model has been validated using physical measurements of a generic drillship model in several broken ice conditions; it predicted thruster forces and motions that were comparable to those observed during dynamic positioning operations.
