Configuration flag CFGMultiDemRate enables demurrage rates that change during the time on demurrage. You can create multiple Laytime Calculations that use different Demurrage/Despatch Rate tables. If the rate table differs between the load and discharge port, two separate calculations must be created.
You can use this form with Demurrage on Account, which supports incremental invoicing for demurrage over the life of a voyage for the discharging port.
To set up multiple Demurrage Rates, right-click a port in a Laytime Calculation and click Demurrage/Despatch Rates.
Enter Days and Demurrage and Despatch Rates.
Rules for calculating:
- If this form is populated, the rates entered here supersede whatever is entered in the port line for the entire laytime.
- If only one Demurrage Rate is defined, it is used for the whole period.
- If a rate is defined with the highest Days less than the demurrage time, that rate is used for all extra time.
- In the example above the following rates are applied:
- First 5 days = $1K/day
- Next 10 days = $2K/day
- Next 15 days and beyond = $3K/day
