Drilling in Iraq

We finished the work on the modernization of the gas turbine, where our task was a.o. very difficult drilling for the casings’ retaining elements. The problem we had to face is the difficult position of drilling – on the edge between two different materials, with a step or drilling into the halve of the old hole. Since the holes were arranged around the perimeter, some of them were also drilled in the ceiling position.
