Here’s another example of laytime calculation in a voyage charterparty agreement:Charterparty Terms:

Allowed laytime for loading: 24 hoursAllowed laytime for discharging: 48 hoursDemurrage rate: $8,000 per day or pro-rataDespatch rate: 50% of demurrage rate

Timeline:

Ship arrives and gives Notice of Readiness (NOR) at the loading port on June 1 at 06:00.Laytime starts counting after 2 hours of waiting time on June 1 at 08:00.Loading completed on June 2 at 04:00.Ship arrives and gives NOR at the discharging port on June 8 at 15:00.Laytime starts counting immediately.Discharging completed on June 10 at 12:00.

Laytime Calculation:Loading:

Calculate the actual laytime used for loading: From June 1, 08:00, to June 2, 04:00, which is 20 hours.Compare actual laytime used (20 hours) with allowed laytime (24 hours): The actual laytime is less than the allowed laytime by 4 hours.Calculate despatch for loading: 4 hours of unused laytime, which is 1/6 of a day. The despatch rate is 50% of the demurrage rate, so the despatch for loading is (1/6 * 0.5 * $8,000) = $666.67.

Discharging:

Calculate the actual laytime used for discharging: From June 8, 15:00, to June 10, 12:00, which is 1 day and 21 hours, or 45 hours.Compare actual laytime used (45 hours) with allowed laytime (48 hours): The actual laytime is less than the allowed laytime by 3 hours.Calculate despatch for discharging: 3 hours of unused laytime, which is 1/8 of a day. The despatch rate is 50% of the demurrage rate, so the despatch for discharging is (1/8 * 0.5 * $8,000) = $500.

Final Settlement:

Calculate the total despatch: $666.67 (despatch for loading) + $500 (despatch for discharging) = $1,166.67.Since there is no demurrage, the shipowner owes the charterer $1,166.67 as despatch payment.

In this example, the charterer is entitled to a despatch payment from the shipowner, as the actual laytime used for both loading and discharging was less than the allowed laytime.
