Abstract

Assessing the mechanical response of soft surficial soil with conventional site investigation tools or laboratory tests is challenging. Alternatively, near-surface soil properties can be measured in-situ offshore using shallow penetrometers, such as the hemiball, toroid or the parkable piezoprobe. The novel sensor concepts are envisaged to infer the undrained soil strength, the consolidation characteristics and the friction parameters for the soil-device interface. Through a combination of laboratory experiments, numerical FE-modelling and offshore field-testing it was demonstrated that the probes can be used to rapidly and reliably measure the soil properties required for the design of shallow subsea infrastructure.
