Development of Integrated Process Management System for Pump Dredge

Abstract

Efficiency of dredging work depends on the types of equipment used, the sediments encountered, whether the work to be performed is new of for maintenance, pre and/or post hydrographic surveying and so forth. Among those, surveying accuracy which is directly determined by the control of the dredge’s position and depth surveying accuracy being surveyed at the dredging point are important factors. The purpose of this study is to develop an integrated process management system for pump dredge. This system is composed of 4 sub-systems such as LADGPS for dredge positioning, dredging point determination, tidal gauge and angular depth sensor for depth determination, and GIS and ENS for process management. The process management system for pump dredge developed was installed on the pump dredge “EUNJIN PD-2”but is now producing work data for comparison with performance of the existing dredge. The data retrieved from the pump dredge process management system up to now shows similar result from the grab dredge management system which was developed previously. It is easy to operate, achieves good accuracy with only 45㎝ unevenness, reduces working period by 20 percent. More precise evaluation of the system comes late after the dredging work is completed.
