Study on Behavior of Drifting Containers due to Tsunami and Collision Forces

Abstract

This study is intended mainly to investigate collision force due to a drifted container by run-up tsunami. Laboratory experiments were conducted to investigate behavior of run-up tsunami and drifting container. Moreover, effect of vertical wall to reduce run-up tsunami was observed. Results show that the vertical wall installed at the leading edge of apron can reduce wave forces acting on container, which may lead to reduce drift of containers. This study also conducted numerical simulation of collision of container with concrete column. It is revealed that the present analyzing method is useful in such simulation.

Influence of Tsunami-Driven Shipping Containers’ Layout on Their Motion

“…Several researchers have conducted hydraulic experiments to investigate detailed measurements of the flow field around a single piece of shipping container and experimentally determined how debris impact is affected by the surrounding fluid [5,6]. Yeom et al [7][8][9] conducted hydraulic experiments and numerical simulations to investigate the drift behavior of a single piece of debris and proposed a calculation scheme capable of investigating the collision forces and collision times resulting from shipping container drift caused by tsunamis. Collision deformation prediction and collision force estimation were also performed to confirm the applicability of collision analysis to reduce such damage.…”

Reflection and Run-Up of Tsunami on Quay Wall and Behavior of Drifted Vessels Due to Tsunami

“…In the past few years, researches have been undertaken to investigate behaviors of drifted objects due to tsunamis (e.g., Matsutomi 2009;Ikeno et al 2006;Inagaki et al 2008). Yeom et al (2007Yeom et al ( , 2008 investigated behaviors of drifted containers and proposed a formula to estimate the collision force by a drifted container. They pointed out that the added mass of a water column pushing the container plays an important role.…”
