Application of Jet Grouting Offshore
Jet grouting can be applied to piles
offshore. In the particular case of
platforms, a modified grouting rig can
work from the jacket bracing or pile top.
This rig will create the grout bulb by
drilling through the open pile after driving
but before the placement of topsides. A jetgrouted
plug will be created inside the pile
to ensure effective load transfer from the
base to the pile steel. Initial estimates show
that this work can be done without
significant impact on construction times.

Marine and near-shore construction also offer attractive applications for this
