Abstract | This paper introduces an inertial measurement system called MOTAN and discusses results from one of its full-scale installations. Recent measurements have shown that the MOTAN system offers a novel approach for determining ice-induced global loads on ships. The system consists of two parts: an instrument for measuring whole-ship motions, and software for processing those motions to obtain global ice impact loads. A background of the MOTAN system is given, along with modelscale and full-scale data to support its feasibility for determining global loads from transient ice impacts. The focus of the paper is full-scale data acquired while the CCGS LOUIS S. STLAURENT rammed old ice floes in the high Arctic. MOTAN-derived global loads are presented for three representative events. Data show that ice impact forces can approach 17.3 MN when ships operate in heavy ice conditions. |
