Pumping system and method

A pumping system for moving a liquid, or a mixture of a liquid and one or more objects, comprising a surface vessel or structure, a pump unit, and a collector device, and a first delivery line connected between the collector device and the pump unit and a second delivery line connected between the pump unit and the surface vessel or structure;

• wherein the pump unit is operable for moving said liquid, or mixture of a liquid and one or more objects, from the collector device to a receiving facility arranged on the surface vessel or structure;
• wherein the pump unit is supported and controlled by the surface vessel or structure via a first support-and-control apparatus and operable to be arranged at a first depth below a surface of a body of water, between the collector device and the surface vessel or structure;
• wherein the collector device is operable to be arranged at a second depth below said a surface of a body of water;
• wherein the pump unit is configured to generate suction in the first delivery line and a positive pressure in the second delivery line;
• wherein the first depth and the second depth are controllable independently of each other.
