Abstract
According to embodiments described in the specification, a pumping system for use in a tailings pond is provided. The pumping system comprises a pump support and at least one mooring element coupled to the pump support. The at least one mooring element has an extended position for fixing the pump support to a bed of the tailings pond, and a retracted position for permitting movement of the pump support towards a shore of the tailings pond. The at least one mooring element is configured for transitioning from the extended position to the retracted position when a distance from the shore to the pump support exceeds a threshold as a result of a change to tailings pond geometry, and for returning to the extended position following movement of the pump support to reduce the distance below the threshold.
