Sulzer Hickham was contacted by a major natural gas transmission joint venture company about a problem they were having with a US manufactured twin shaft gas turbine at a compression facility in the northern US. The customer was looking for an alternative service provider to the OEM in order to perform an inspection on the gas turbine unit. Sulzer Hickham was called in on the project because of successful inspections and services previously provided to one of the joint owners.
Shortly after the overhaul had commenced it became obvious that a simple hot gas path inspection would not be sufficient. It became evident that a major overhaul would be necessary. This presented a timing problem as a major overhaul had not been in the original planning. In addition to the usual work performed in a major overhaul, it was revealed that the exhaust plenum needed replacement, regenerator work was required, and replacement combustion elbows would have to be sourced.
Many of the parts were sent to the Sulzer Hickham USA facility in Texas. This included: both the HP and LP rotors, all combustion components, 1st stage nozzle, 2nd stage nozzle assembly, including all the hatchet blades in the casing, the exhaust frame, starter turbine, gearbox, all bearings, various motors and smaller pumps and the IGV’s. All the parts were repaired and coated with Sulzer Hickham USA Hi-Coat materials where necessary. Additionally, an operating speed balance of the HP rotor was performed.
The reassembly at the compression facility in Michigan went very smoothly. Sulzer Hickham USA’s field service personnel did an excellent job and received accolades from many different levels within both joint venture partners organizations. The client has recommended us and will be returning with future orders.
