Estimation of the impact ice load acting on the facility preventing from overtopping of ice floes

Abstract

In the past ten years, there has been a tendency for frozen areas in the Okotsk Sea to become narrow, possible because of global warming. In the winter of 1991 waves broke over the south breakwater at the port of Abasiri and bringing with then ice floes which overtopped the breakwater causing grate damage to the oil pipelines and dolphins behind the breakwater.
In this paper, the authors proposed the facility preventing from overtopping ice floes and design method for the phenomena through the systematic experiments of the impact ice load acting on pile structures and the overtopping velocity of ice floes.
