LOWER AND LAY
OR DITCHING THE MAIN LINE ......
The pipe has been welded, coated and inspected, the trench dug, and now it's time to get it into the ground
The sidebooms gather.........
Up to six sidebooms move in one by one and take up the weight of the pipe..
This 360 digger with the clever blade sweeps all the bearers and debris out of the path of the booms
And slow and steady they move off down the spread..
And they disappear into the distance
The end of the pipe is held in the air whilst the tie-in is cut to size
from up and down the line
When everyone is in line, the rear booms swing the pipe out over the trench
In a process known as "walking it in", the booms take turns in relaxing their strop, moving forward a length, and taking the weight again, the rear two guiding the pipe into the trench.
every inch given a final careful inspection before it goes below the ground
Then the welders move in
