장기간 파랑 및 바람관측자료에 의한 포항신항 하역중단 원인분석

Abstract

The reason for the occurrence of downtime problems in Pohang New harbor was analyzed by using the extensive field measurement data of short and long period waves and winds for more than one year, the precipitation data provided by KMA(Korea Meteorological Agency), and the downtime records during the measurement period. It was found that downtimes occur because of the short period wave of which height is higher than loading criteria and the swell with even smaller wave height but longer period(more than 10 sec) and fig-waves of which height is higher than loading criteria. Long period components(more than 5 min.) is seems to be related with the downtime problems. This study shows what was able to improve harbor calmness if short period waves and swells were blocked effectively.
