When installing a jacket structure, a delay of a few weeks between foundation pile driving and jacket installation is typical. In this period biofouling develops on the inner surface of the pile walls.
Jacket pile cleaning
As surface cleanliness of the pile is critical for effective grouting the jacket pins into the foundation piles, all loose debris and marine growth needs to be removed quickly and effectively to ensure a reliable grout connection.
For jacket foundation piles we build inrunner-type robotic frames with dredging capabilities, or we apply diving techniques.
