Data centers are ushering in a new era of electricity demand—and existing power plants are being called on to generate more with the infrastructure already in place. As operating hours increase and reserve margins tighten, the reliability of water treatment systems is becoming essential to maintaining power generation. After decades of relatively modest electricity growth, […]

At Petro Vietnam Vung Ang 1 Thermal Power Plant, Mechanical Dynamics & Analysis (MD&A) experts repaired damaged babbitt bearings and refurbished journals for a customer on a steam turbine-generator with the unit in an assembled (rotor-in) condition. The unit was forced from service due to turbine bearing failures. In a quick turnaround, journal refurbishment occurred in the […]

Mechanical Dynamics & Analysis (MD&A) completed a carefully coordinated 7FA gas turbine hot gas path inspection, 7FH2 generator inspection and repairs in just 19 days, providing all services, labor, and parts. The customer contracted MD&A to perform the inspection and emergent repairs on a tight schedule. Our industry experts completed the work on time maintaining full customer communication […]

Mechanical Dynamics & Analysis (MD&A) announces Portable In-Situ Air Flow Test stand capabilities that allow for immediate and conclusive data on gas turbine nozzle performance. This flow test apparatus provides efficient gas turbine air/gas flow analysis and is offered by MD&A Fuel Nozzle Services Division/ Integrated Combustion Solutions (ICS). The typical call to action is a control room combustion […]

Mechanical Dynamics & Analysis (MD&A) recently completed an overhaul at a combined cycle plant consisting of gas and steam turbine majors, a steam turbine generator minor inspection, and a gas turbine generator major inspection. The customer combined scope was the largest single project implemented at the site since the combined cycle plant was commissioned. MD&A sent all 3 rotors from […]

Mechanical Dynamics & Analysis’ Control Systems Division (MD&A Control Systems) replaced an industrial co-gen turbine’s original mechanical-hydraulic (MHC) controls with an electronic governor, electro-hydraulic trip system and self-contained control valve actuator. The primary drivers for the project were the operator’s desire to increase the long-term maintainability and reliability by replacing the MHC components that had […]

Mechanical Dynamics & Analysis (MD&A) recently performed multiyear outages for a customer on several different units in Colombia. First unit:  This was a major outage and generator test & inspection. In addition, this unit was retrofitted with a new rotor, bearings, and steam path components that required machining, including installing and fitting new nozzles. MD&A […]
