Balance

Hendrie is still in a good mood.
Working on a sunday in overtime.
With two men from a subcontractor waiting for the safetyprecautions are all taken care of before they can start to switch a balancing weight to another spot on the coupling between steamturbine and gasturbine. (310° further, so in our opinion 50° back)
Our competence center has determined that that must be the solution to solve the vibrationproblems on the shaftline.

They have a maximum time to do the job in 30 minutes; after that time we have to bring the shaftline on the hydraulic turning gear again.
The temperature of the steamturbine is still appr. 220° centigrade so maximum standstilltime is 30 minutes.
