Guest seminar by Dr Shiaohuey Chow, University of Western Australia

Free-fall penetrometers (FFPs) – a new generation of offshore site investigation tools - offer significant potential as a cost effective solution to characterise seabed properties. FFPs are instrumented projectiles that are deployed by allowing them to free fall and embed into the target sediment. The use of FFPs in offshore geotechnical site investigation has gained increased interests, particularly in characterising the soil strength of shallow seabed crucial for applications such as pipeline design and submarine landslide survey. This seminar will present a centrifuge study of a model FFP in clay and an improved FFP interpretation to estimate soil strength and consolidation properties. The seminar will also cover the development of a prototype FFP and assessment of its performance through field trials in the Swan River, Perth.
