ESTIMATION OF WAVE DIRECTION USING IMAGE ANALYSIS OF BUOYS IN THE MARINE CONSTRUCTION AREA
Wave monitoring at marine construction sites is of great importance in maintain the safety of workers and construction quality. In particular, a ship wave generated near a construction site hits ships and floating structures immediately and potentially causes a severe accident. A simple and low-cost...

| description | Wave monitoring at marine construction sites is of great importance in maintain the safety of workers and construction quality. In particular, a ship wave generated near a construction site hits ships and floating structures immediately and potentially causes a severe accident. A simple and low-cost monitoring system using buoy image analysis has been previously developed for a ship-wave warning system. However, this method cannot identify the wave direction, and thus, the measured wave may not reach the construction site. The purpose of this study is to propose a method of estimating wave direction using buoy image analysis. We conducted ship-wave tests in marine construction sites and confirmed that the accuracy of estimated wave direction was within ±22.5 degrees from the true value. The results confirmed the method’s capability of predicting a wave attack on a construction site. |
