Dredging calculators by dredger type

Dredging production calculator: Cutter suction dredger

For a cutter suction dredger, production per shift depends on the cycle: how long it takes to load, travel, discharge and come back, and how much of each load is in-situ material. The calculator below is preset for a cutter suction dredger; every assumption is on screen for you to change.

What the calculator works out

• Cycle time and loads per shift, or mixture production for a cutter.
• Cubic metres per shift and per hour.
• Fuel per shift and per cubic metre, and the CO2 that goes with it.

From estimate to evidence

In a full deployment, Idris, the dredging colleague, builds each shift report from the dredger's feed, takes downtime reasons by voice and reconciles production to the survey, so the monthly claim carries its evidence.

Estimates here are for planning. The survey decides what is paid.
