Spudcans are inverted cones which are mounted below the jack-up legs. Via the jack-up leg, a cable was lowered and attached to the spudcan by divers. After that, the spudcan was lifted and bolted to the leg from the inside. A very precise job. For support during the operation, our engineers were present on-site at the time the spudcans were installed. Therefore, setbacks could be immediately solved, which ensured a swift operation.
Contact us if you would like to discuss your heavy lifting project. We are eager to help you! Heavy lifting equipment was designed for the lifting of four jack-up legs. A hydraulic pin-pusher lifting tool lifted the legs at the top.
The soil was idealized as an elastic-perfectly plastic material obeying a Mohr-Coulomb yield criterion and the large displacement analysis was carried out using Remeshing and Interpolating Technique with Small Strain RITSS model to simulate the full installation and extraction process. The numerical results were compared with… Expand.

This paper provides a method that can quantify the installation risk by a set of percentile curves of penetration resistance against depth. The percentile curves can be quantified through combining a random large deformation finite element method with Monte-Carlo simulation. The spatial variability in seabed soils can be considered and the penetration resistance curves through the random soils can be obtained.
This model was verified by a spudcan installation penetration into deeper seabed.
