PROPELLER FOR SUEZMAX

[TEOMECH]

Hello....
Is there anyone who can help me out this...
Recently I found that two almost sister vessels, one ice class 1A and the other one common, with the same propellers..
All i know is that CLASSIFFICATION SOCIETY for ICE CLASS 1A
REQUIRES blade thikness bigger and different fitting...
So how possible it is that the weight be the same?
I dont know the material composition % but both of them are consists of Ni-Al-bronze..and weights around 37000kg...

Is the propeller diameter and blade area ratio (BAR) the same ? That would help give the same weight even if thickness was greater.

Could the ice class ship have reduced the prop area compared to the "normal" in order to live with the same shaft and avoid other changes ?

Though unusual, there could be a number of reasons. You will want to speak to the Classiifcation society on this issue if you have any questions as to suitability, or problems in service.
