Preliminary caisson geotechnical designs are required for two foundation types, namely support and anchor foundations. Both have different design challenges: for top loaded support foundations, it is possible to directly obtain optimum geometries (i.e. factored loads equal factored resistances) for given VHM loads.
Spudpen calculates independent Jack-up rig leg penetration behaviour during preloading according to ISO Standard 19905-1 (2016) including foundation calculation methods, e.g. squeezing for sand and clay calculations. Note: the Spudcan software is CLI (command line interface based) and is text based.
