Despatch due to Charterers	13520.58	USD

The shipowner argues that the vessel tendered Notice of Readiness on the 5th of July during office hours, therefore, according to the Charter party (see extracts from the Charter party previously discussed), laytime to start counting next day, on the 6th of July, at 08:00 and continues till 10:55 next day, the 7th of July, as the berth was occupied (see the Statement of Facts, previously presented).

Laytime stops counting at 10:55 as the anchor was up for proceeding to anchorage #2 for inspection. The laytime resumes counting from 12:15 till 13:15 as the vessel is idle waiting for preloading inspection. Unfortunately, the holds are reproved and the vessel fails to pass inspection and therefore has to proceed to anchorage #4 for additional cleaning. The time not to count till the next inspection. The vessel is cleaning holds till the end of the day on Thursday, and also on Friday and Saturday, till 14:00, when she is finally ready to proceed for new inspection. However, the laytime stops counting at 12:00 on Saturday (SSHEX 12:00 clause of the Charter party) and not to resume till 08:00 Monday. However, loading is completed at 10:55 on Sunday. Time not to count. Time for fumigation not to count as well.

Therefore the Shipowners consider despatch of 13520.58USD due to Charterers, and request the Charterers to provide comments and/or confirmation onto the Owners' calculation.
