Port Dredging Production, Sediment Disposal & Project Cost Tool
Port Dredging Production, Sediment Disposal & Project Cost Tool
Turn surveyed cut quantities into a dredging and placement plan. Screen equipment productivity, hopper haul cycles, disposal capacity, sediment classifications, environmental restrictions, schedule exposure and total project economics.
Dredging Cut / Work-Zone Register
Areas × design cut thickness × (1 + allowance) generate in-situ quantities. Swell converts to loose volume for placement. Assign a spread and disposal site; enter material and deadline as planning assumptions.
| Use | Reach / cut | Area m² | Cut m | Allowance % | Swell × | Sediment | Spread ID | Site ID | Target day | In-situ m³ | Remove |
|---|
Equipment Spread & Transport Register
Production rate is in-situ m³/h during active dredging. Hopper/barge spreads lose time to one round trip plus discharge per loose-volume payload; a pipeline spread uses the entered productive rate without transport-cycle time.
| Use | Spread ID | Type | Dredging m³/h | Payload loose m³ | Haul one-way km | Transit kn | Discharge h | Availability % | Spread USD/day | Remove |
|---|
Placement Site, Intake & Capacity Register
Capacity and intake are stated in loose m³ for this model. Real measurement and permit quantities may use different bases. Approval and sediment acceptance flags cause critical holds rather than automatic permission.
| Use | Site ID | Placement type | Sediment accepted | Remaining loose m³ | Intake loose m³/day | Placement USD/loose m³ | Authorization | Remove |
|---|
Weather / Work Restriction Register
Day windows are relative to project mobilization. A closed window has 0% operational availability. Other percentages apply as daily work-fraction reductions for all spreads; multiple restrictions use the lowest active percentage.
| Use | Restriction | Start day | End day | Available % | Source / basis | Remove |
|---|
Permits, Sediment & Environmental Readiness
Outstanding critical checks override apparent schedule feasibility. They do not assert that the project is noncompliant; they identify evidence and authorization still to be verified.
| Use | Verification item | Discipline | Critical? | Status | Responsible / evidence | Remove |
