回复楼上两位，船上发电机过载能力也是可以的。见下：

During continuous duty (S1), the following overloads are allowed:10% for 1 hour

15% for 10 minutes

30% for 4 minutes

50% for 2 minutes

These overloads must be occasional and followed by one hour of running at normal load or less.

 还有，关键是老外就可以做到1950kw的起重机功率，推荐发电机2000kw（2500kva），我是很奇怪他们怎么做到的。应该同样的ABB/西门子的驱动啊。
