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 […]

Steam plays a prominent role in the Power Industry. When a boiler goes down, companies can be faced with a potential loss of hundreds of thousands of dollars for each minute of lost production time. Although many plants operate 24/7 without interruption, it is very likely that a temporary steam plant will be required at […]

Mechanical Dynamics & Analysis (MD&A) repaired a Frame 5 gas turbine rotor.  MD&A replaced 1st and 2nd stage buckets, repaired the seal area on the row 1 turbine wheel, performed compressor blade blending, and machined the thrust collar to accommodate the newer style thrust bearing at the No. 1 bearing. During their planned major inspection, the […]

For many years, the OEM fix for major cracking or shell distortion was replacement of the defective shell, also referred to as casing by some OEMs, with new. Mechanical Dynamics and Analysis has provided an alternative to shell replacements which includes fixing the existing shell to extend its life. MD&A recently welded and repaired the HPIP […]

Flow-accelerated or flow-assisted corrosion (FAC) is the uncontrolled dissolution and transportation of iron oxides in a steam-water cycle system that occurs in both single-phase locations (water) and two-phase locations (water and steam). Single-phase FAC can be mitigated by chemical controls, but two-phase FAC remains largely unaddressed by industry’s available product options due to the challenging nature […]

Mechanical Dynamics & Analysis (MD&A) recently completed generator field rewind with a rotor slot dovetail repair on a customer’s GE® 650,000 KVA generator field. The work scope was performed at the customer’s direction with regards to applicable Technical Information Letters. Incoming visual and mechanical inspections were first completed, as well as a runout inspection in the lathe which […]

The 2850Si Silica Analyzer is a water analyzer that features fast and reliable silica analysis, integrated phosphate measurement and a built-in sequencer, allowing you to do more with a single analyzer. The significance of silica measurement in power plants Silica monitoring is vital for controlling contamination levels in the ultrapure water used throughout the plant. […]

Losing control – of the scope, scheduling, workers, contractors, bottlenecks, and safety – is the biggest challenge of any turnaround, ultimately leading to inevitable delays in timetables and overruns in budget. These issues and more can be improved by better management of industrial workforces. By being connected in real-time to what’s going on in the […]

A web-based condition monitoring solution can help power plant operators quickly identify emissions gas analyzer problems, enabling timely corrections. The technology can also allow experts to monitor multiple sites remotely, adding flexibility to operations. Electricity, water, and heat are such a part of our everyday lives that we only notice them when they’re gone. Energy […]
