Searching root cause of vibration in the Mars 90 turbine

This week we worked on finding the root cause of the slight vibration on the turbine we had previosly boroscoped the compressor and did not find any visible damage so Williams brought in a Solar tech to try and find the cause we disassembled th line and found it to be a full day job with torque specs of 9500 ft pounds it takes some heavy duty impacts I have some pictures of the disasembly and assembly enjoyAlso have some pictures of the radiator that cools the turbine I was up on it cleaning the coils I used a man lift to get up on top and spray it with coil bright then washed it with water I also have been helping Ernie the welder at the Mount Vernon station on new piping install going in the Seatle area we have been cuting and fitting flanges on pipe and fabricating other pieces needed..
