MAPS (Monash Advanced Pipe testing System)
A special sophisticated 2D actuator setup (Monash Advanced Pipe System or MAPS) was purpose built to simulate the pipe walking on a model clay seabed. Element pipe testing was conducted for both drained and undrained pipe displacement rates. The results led to the characterisation of the governing parameters on the axial pipe-soil interaction behaviour.
