> In order to install the wind turbine generators, jack-up vessels require to jack down to the seabed to provide a stable platform for the operations. Below is a list of our jacking-related services:
- Leg penetration analysis based on ISO 19905 standard
- Risk analysis
- Jacking footprint analysis and determination of safe jacking distance
- Punch-through risk determination
- Full 3D model of jack-up vessel, spudcan and subsoil
- Spudcan extraction analysis
- Analysis of complex soil conditions with respect to the jacking feasibility
- Jacking on seabed slopes, boulders or any other challenging environment
- Third-party review of the engineering reports

Simulation of jacking footprint on the nearby seabed.
The extent of the footprint depends on spudcan geometry, final penetration, shape as well as soil layering and geotechnical properties.
Spudcan boulder interaction analysis. Boulder size, soil geomechanical properties, soil layering, spudcan shape as well as the jacking position with respect to boulder are all amongst the parameters influencing the eccentric forces on the spudcan.

FEM simulations: Left: visualization of the plastic strains around monopile annulus subject to a collision; Right: monopile out-of-plane displacements in 1st mode of natural frequency.
Simulation of a monopile lowered down by a crane on a scour protection layer. The velocity magnitudes are visualized.
The loads on the monopile annulus are monitored and later checked if they cause any plastic deformations or local buckling.
