... various water depths and pipe–soil interaction rates. A series of centrifuge tests were completed using a scaled model of a 0.324 m diameter pipe in dense silica sand with a viscous pore fluid. The model pipe was pushed into the model seabed at a 60° penetration angle, at various penetration rates...
