Final Penetration

Out of the four piles, three are driven to their final penetration of almost 138 meters into the seafloor. Can you imagine how much energy is stored in each pile?
Obvious this is necessary to take the load of the 4000 tons platform module which will placed on top of it somewhere next week.
You also can see the number P-6 on one of the piles to the right, it means that the complete pilestring consists of 6 shorter piles (add-ons) welded to each other.
By the way; the yellow tool on top of one of the piles on the left is the Menck Hydraulic hammer.
