Steam and Gas Turbine Control Systems
As your plant approaches its scheduled maintenance period we encourage our customers to review their controls, valves and actuators, especially if the plant is more than 10 years old. Often turbine uptime periods can be for 5 years and so if a control becomes obsolete in that period it puts the plant at risk. Additionally old valves and actuators that have been repaired many times and also their designs more susceptible to oil contamination, can be upgraded to the latest, robust all electric valves or hydraulic actuators designs to meet the latest reliability demands set by our customers. Goltens can offer asset management services for your Woodward products focused on minimizing risk and cost, and maximizing reliability. In addition to offering turnaround services Goltens can recommend and provide turnkey upgrades, often also improving plant safety and efficiency so revenues.
We can provide any of the below system upgrades as turn key solutions:
