Vessel Capacity Calculator
Add up hold volumes and calculate volumetric capacity for the cargo’s stowage factor, the DWT limit and the cargo that can be carried. No sign-up needed; results update as you type.
See the system that does this automaticallyOpen the live demoVessel Capacity Calculator: worked example
The example table has 5 rows; other values: Cargo stowage factor 1.33 m³/t, Available DWT (after fuel etc.) 55,600 t. With these values the results are:
| Total hold volume | 70,900 m³ |
|---|---|
| Cargo by volume | 53,308 t |
| Cargo that can be carried | 53,308 t |
| Binding limit | Hold volume |
How to use: Vessel Capacity Calculator
- Enter your own values: Cargo stowage factor, Available DWT (after fuel etc.).
- Add or delete table rows as needed; totals update automatically.
- Results are calculated as you type: Total hold volume, Cargo by volume, Cargo that can be carried, Binding limit.
- Check every step of the calculation in the formulas below.
How is it calculated?
- Share (each row) = [Volume (m³)] ÷ [Σ Volume (m³)] × 100
- Load (each row) = [Share] ÷ 100 × min([Σ Volume (m³)] ÷ [Cargo stowage factor]; [Available DWT (after fuel etc.)])
- Total hold volume = [Σ Volume (m³)]
- Cargo by volume = [Σ Volume (m³)] ÷ [Cargo stowage factor]
- Cargo that can be carried = min([Cargo by volume]; [Available DWT (after fuel etc.)])
Ship calculations are estimates based on standard formulas. Loading, stability and draft decisions must be based on the ship’s approved documents and loading computer.
Other tools running on Vessel Hydrostatics Engine
Calculates DWT, displacement, draft, trim, TPC and MCT relationships with standard naval formulas; results must be checked against approved vessel data.
FCRSOFT
FCRSOFT does this for you automatically
You don’t need to do the calculations and checks on this page by hand every day. FCRSOFT derives them all automatically from the records entered in the field.
- DWT, TPC, draft and capacity data are stored on vessel cards.
- Certificate and document expiry dates are tracked, with warnings before they lapse.
- Voyage estimates use vessel data automatically.
Frequently asked questions
How is Vessel Capacity Calculator calculated?
Add up hold volumes and calculate volumetric capacity for the cargo’s stowage factor, the DWT limit and the cargo that can be carried. The calculation uses Vessel Hydrostatics Engine: Calculates DWT, displacement, draft, trim, TPC and MCT relationships with standard naval formulas; results must be checked against approved vessel data.
How is Cargo that can be carried found?
Cargo that can be carried = min([Cargo by volume]; [Available DWT (after fuel etc.)]). With the example values (Cargo stowage factor 1.33 m³/t, Available DWT (after fuel etc.) 55,600 t) the result is 53,308 t.
Worked example: Vessel Capacity Calculator
Example values: Cargo stowage factor 1.33 m³/t, Available DWT (after fuel etc.) 55,600 t. Total hold volume: 70,900 m³; Cargo by volume: 53,308 t; Cargo that can be carried: 53,308 t; Binding limit: Hold volume.
Is Vessel Capacity Calculator free?
Yes. The tool is free, needs no sign-up and runs in your browser; the data you enter is not stored.
Can FCRSOFT do this calculation automatically?
FCRSOFT stores DWT, TPC and draft data on vessel cards and uses it automatically in voyage estimates. You can try the Fleet & Vessel package in the live demo without installing anything.
Do the results replace official ship calculations?
No. Ship calculations are estimates based on standard formulas. Loading, stability and draft decisions must be based on the ship’s approved documents and loading computer.
