Mechanical Dynamics & Analysis (MD&A) experts recently performed a thermodynamic analysis to assist our client in converting their coal and natural gas plant to combined cycle operation. The customer was able to locate a gray market Gas turbine and Heat Recovery Steam Generator (HRSG). Our team modeled how each component would interact with one another, and were […]

MD&A’s San Antonio Service Center can extend the service life of gas turbine components whose OEM service limit has passed or whose configuration is no longer suitable to operate. Significant savings can be realized by opting for lower-cost repaired spares instead of new parts. Elevated temperatures take a big toll on gas turbine components. Repair […]

Mechanical Dynamics and Analysis inspected and repaired an A-10 frame High-Pressure rotor.   The unit was a 3600 rpm, 90 MW combined cycle unit.  MD&A’s Turbine-Generator Repair Facility performed the incoming inspections / evaluations, repair straightening of the rotor, final inspections, as well as high speed balance. Incoming inspections and evaluation consisted of blast cleaning, NDE, visual inspections, […]

President Trump campaigned on a promise to reduce regulation and control regulatory costs. One of his first actions after taking office was to issue an executive order calling for the elimination of two existing regulations for every one new regulation issued.

On many combined cycle projects, the major decisions about boiler chemistry are left until after the plant has been designed, equipment is procured, and construction is well underway. However, the best time to make these chemistry decisions is in the design phase of the project. That enables the engineering, procurement, and construction (EPC) contractor to […]

Along with producing power from 99 turbines, the 309-MW Hornsdale Wind Farm in South Australia has helped trial new technologies that could ramp up power system security and reliability. At first glance, the

The Frades II pumped-storage hydro project in Portugal took advantage of existing dams to incorporate a scheme that includes the largest variable-speed reversible units installed in Europe. The facility

The power industry is changing and leading companies are turning to digital technologies to revolutionize their operations. Monitoring and diagnostics centers are leveraging vast amounts of data from around
