Production Capacity vs. Pipeline Diameter - CSD
Production Capacity vs. Pipeline Diameter
The productivity of a cutter suction dredger is defined in two ways: excavation productivity and pumping/pipeline transport productivity.
The smaller value of the two represents the actual productivity.This is because the dredger operates with simultaneous cutting and discharge, which are mutually restrictive.

| Solid production | Suction pipe dia | Discharge pipe dia |
| 100m³/h | 12inch(=300mm) | 10inch(=254mm) |
| 120m³/h | 12inch(=355mm) | 12inch(=300mm) |
| 300m³/h | 16inch(=406mm) | 14inch(=355mm) |
| 350m³/h | 18inch(=420mm) | 16inch(=406mm) |
| 400m³/h | 20inch(=500mm) | 18inch(=420mm) |
| 500m³/h | 22inch(=558mm) | 20inch(=500mm) |
| 800m³/h | 24inch(=609mm) | 22inch(=558mm) |
| 1000m³/h | 26inch(=660mm) | 24inch(=609mm) |
| 1500m³/h | 28inch(=711mm) | 26inch(=660mm) |
| 2000m³/h | 30inch(=762mm) | 28inch(=711mm) |
| 2500m³/h | 31inch(=800mm) | 29inch(=750mm) |
