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.
...
- 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
- Demurrage/despatch amount for the calculation is calculated for each port individually based on this setup - then summed up.
- The average demurrage (or despatch - whichever applies to the port) rate for each port - based on this setup and the balance days at the port - is displayed in the Dem Rate/D and Des Rate/D columns in the Laytime Calculation's itinerary grid accordingly.
For example:
- let's say, our calculation has the loading port NEW YORK - with 7 demurrage days balance - and the discharging port BOSTON with 17 days demurrage days balance.
- demurrage amount for the calculation - based on the example setup above - will be:
- NEW YORK demurrage amount will be: 5*1,000 + 2*2,000 = $9,000
- BOSTON demurrage amount will be: 5*1,000 + 10*2,000 + 2*3,000 = $31,000
- Total demurrage for our calculation is $40,000.
