由于船东过错导致的延误

且行且止

请教杨老师和各位同仁，

合同订明load/disc r 5 tll days shinc. 适用GENCORE 94格式合同。

船舶在装港已经进入滞期。

0015lt Apr 5th, vsl arrived disport and NOR tendered.
0015lt Apr 5th - 1715lt Apr 6th, vsl at anchorage waiting for berth available.
(berthing scheduled on 1715lt Apr 6th as per harbour master).

1715lt Apr 6th, pilot was cancelled due main engine out of services
0025lt Apr 7th main engine resumed ready
0025lt Apr 7th - 1120lt Apr 10th, vsl at anchorage waiting for berth available.
1120lt Apr 10th, POB

对于0025lt Apr 7th - 1120lt Apr 10th，3天的等泊时间算不算船东过错导致的延误，换句话说，船东能否向租家收取这段时间的demurrage？
