Shearing bolts of the fixation of the coupling between the turbine and the generator (09 MW)

Bonjour

In the new gas treatment plant located in Algeria (JV), the first gaz was exported in the mid of December 2017) , two weeks ago from now , during the operation of the Solar turbine Generator it was happened a serious problem for two machines (09 MW by machine), that was the shearing bolts of the fixation of the coupling between the turbine and the generator
The investigation is ongoing to find the real causes of this failure by the Client /Contractor
May be someone met the same problem in the past that could give me his feedback about an idea about the failure , causes and the solution implemented to solve this problem definitely

Thank you in advance for your feed back

Best Regards

Djamel

Hi Ismail06,

Perhaps I should have said SOME OF YOUR BUDDIES ON ENG-TIPS WOULD APPRECIATE a general arrangement drawing and nicely detailed pictures of the failed bolts' fracture surfaces and the couplings would be useful to mull over until the sheriff arrives.

thanks
