Where there is drill-cut there is often debris present, which needs to be re-located during the dredging operation (thus affecting the dredging performance). There are several types of drill-cut which means it can be difficult to predict the consistency. Some drill-cut is sticky, which means that objects/debris may be hard to remove.
Subsea cleaning of the machine to reduce deck handling should be considered..
Drill-cut is easy to transport over distances– it spreads easily behind the machine.
Usually drill-cut is an acceptable surface to relocate the machine by using tracks, but could be a challenge if consistency is sticky.
Dependent on current, visibility can be a problem when dredging this material.
