Concrete Armor Blocks
CITIC Pacific Mining is proposing to increase throughput at their Sino Iron Terminal in Cape Preston, Western Australia, using self-propelled transshipment shuttle vessels. Initial assessment using desktop methods (PIANC, 2015) indicated that the rock slope adjacent to the berth face would incur damage due to wash from the side thrusters and the main propeller. Large scale physical model tests were undertaken to measure wash velocity and stability. The physical modelling demonstrated that the rock slope was more stable than expected. Additional tests were completed to investigate the efficacy of Articulated Concrete Block Mattresses to protect the slope.
