This was the project to dredge and unload in Ishinomaki industrial port in Kama area in western Ishinomaki.
Ishinomaki port also had lost its function for a while due to the Great east Japan earthquake and had an emergency rehabilitation.
For this dredging, which was to secure the water depth in the port, we mobilized our highly evaluated air pressure vessel for discharging and we did it in minimum volume.
