Soil models can be built in geotechnical centrifuges under specified procedures with good reproducibility between 40 and 100 % relative density. Nevertheless, many problems require model making with loose samples, especially when seafloor conditions are to be represented. Samples for arm centrifuges are disturbed during transport of a model container from the laboratory to the centrifuge and they require complex procedures to create a model in-flight. Nevertheless, loose granular soil samples can be produced in flight in a geotechnical drum centrifuge, which even offers a large area for potential offshore tests. The procedure adopted to create the sample, as well as first site investigation tests using a piezocone, and shallow foundation tests will be presented, together with a critical discussion on the quality of the sample.
