If you have a question about this talk, please contact Zelda Stuck.

This talk will describe the phenomenon of deep sea soft clay crusts found off the west coast of Africa and the possible implications of its presence to hot-oil pipeline design. A discussion of the possible hypotheses for the crust’s origin will be followed by the presentation of some surprising results from Cam-shear testing on pipeline coating interfaces. Evidence for biological activity within the crust in the form of burrowing invertebrates (worms) is presented with a focus on the mechanical behaviour of worm faecal pellets extracted from deep ocean cores.

This talk is part of the Engineering Department Geotechnical Research Seminars series.
