1. A system for movement of fluid in a tank, the system comprising:
a tank; and
at least two pumping sets, each pumping set comprising:
an external pumping line disposed along an exterior of the tank such that the external pumping line is in fluidic communication with an interior of the tank at two separate points of the tank via two ends of the external pumping line, and
a pump configured to circulate fluid through the external pumping line, wherein each pumping set is configured to collect fluid from the tank at one end of its respective external pumping line, circulate the fluid externally around the tank through its respective external pumping line and discharge the fluid back into the tank through the other end of its respective external pumping line, and
wherein each pumping set is configured such that a flow of fluid in its respective external pumping line is reversible.
