Ørsted Bioenergy & Thermal Power A/S intends to award a contract to GE Power Denmark ApS without prior publication of a contract.
Since Sept. 2019 there has been an increase of vibrations on the SSV3 IP turbine. The problem has been during rundown but also during normal operation.
After some investigation and measurements an emergency stop was made from 8.-23. Feb. 2020 for control of bearing and video inspection, which resulted in a finding of crack indications in the IP rotor. After the emergency stop the vibration amplitude during rundown was still extremely high.
The assessment of the IP turbine condition is critical, and damage inside the IP turbine cannot be assessed without opening it.
The contract covers works and supplies in relation to the repair of the IP turbine. More specifically the contract covers:Opening of SSV3 IP turbine, rotor standard inspection, replacement of row 1-Flow 11 and 12, including new blades, rotor balancing, investigation of crack found in row 7-Flow 11.
