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 […]

Steam turbine work on the international stage can have its challenges, but also its successes. Mechanical Dynamics & Analysis (MD&A) was contracted to inspect, analyze, and then straighten a Toshiba® steam turbine rotor in Abu Dhabi, United Arab Emirates. MD&A launched its team into action for a full analysis of the issues followed by a resolution of […]

Decarbonization has become such a central attribute at Mitsubishi Power, the leading power generation and energy storage company has designed a business strategy that reaches well beyond its legacy gas turbine business to enable it, said Mitsubishi Power Americas President and CEO Paul Browning. “Four-and-a-half years ago, we put together our five-year strategic plan, and […]

The necessity of flow originated with our customers. After working with lead gen marketers on one-off campaigns, it became clear that their sales teams needed nurtured leads, the kind that engaged at multiple touchpoints with the brand and were ready to learn about solutions. Each flow campaign looks a little different, but at it’s core, […]

Across the power generation industry, operators are under increasing pressure to do more with less. Aging assets are being pushed to operate longer; maintenance windows are shrinking, and expectations for availability and safety are rising. With capital budgets under pressure, plant owners are looking closely at modernization opportunities that deliver measurable reliability improvements without adding […]

Elevated temperatures take a big toll on gas turbine components risking cracks, corrosion, wall thickness, and material condition. Repair enhancements can extend a part’s life by slowing its degradation and pushing out its usable service life. Operators can see significant savings by opting for lower-cost repaired spares instead of new parts as demonstrated in the following case studies.

The countdown was set for T-19 days to complete a 7FA gas turbine hot gas path inspection together with a 7FH2 generator inspection and repairs providing all services, labor, and parts. While the average time for such project can be much higher, the Mechanical Dynamics & Analysis (MD&A) team of experts was able to perform a carefully

As fossil plants look for new methods of minimizing corrosion, on-line analyzers are gaining importance. An analyzer for chloride and sulfate allows rapid response to rising levels of these corrosive ions. Learn more

Conductivity sensors can do more than just measure conductivity. Calculated values using conductivity data can provide valuable cycle chemistry information, confirm on-line sensor values, save time, and reduce costs. Learn more.

Oxidation reduction potential (ORP) measurement continues to be an essential tool in power plant water chemistry to monitor chemical dosing and impurities which can initiate corrosion. Advances in sensor technology make ORP measurement easier than ever before. Read the article.

The most common causes of corrosion are low pH, the presence of dissolved gas (oxygen), under deposit attack, and areas weakened by mechanical stress which ultimately leads to fatigue cracking. Check out how to prevent it!

Learn about a proactive approach for predicting when resin exhaustion will occur that offers significant benefits over the traditional elapsed time and totalized flow methods.

Organic contamination in cogeneration water cycles is capable of causing process disruptions and catastrophic damage to expensive capital equipment. Key to confirming and troubleshooting organics removal is reliable on-line total organic carbon (TOC) measurement. Check out what If organics are in your cogen process water?

Continuous silica measurement is the best means to protect against contamination from spent anion resin and from steam carryover. Check out how to minimize risks of corrosion with accurate silica monitoring.

Check out how US major electricity and natural gas provider in the US Midwest detected ppb-level chloride and sulfateions accurately in their cycle chemistry and avoided plant shoutdown. Start monitoring your water-steam on-line and react quickly to any excursions.

The very low maintenance of optical sensors has transformed dissolved oxygen measurement at one of Brazil’s biggest power plants.

Ensuring continuity is essential for power and utility services. Security experts in this industry must protect systems and data from cyber threats.

Cybersecurity compliance can seem overwhelming at first. There is a multitude of standards, tools, and resources on the market to help organizations through the process.
How do I find legitimate vendors?
If any vendor tells you that using their tool guarantees compliance with a given regime, consider them suspect. When you speak with a vendor, ask them to

November is Critical Infrastructure Security and Resilience Month. In this blog post, we’ll look into what security and resiliency really mean for critical infrastructures such as the energy sector, water monitoring systems, and emergency services.

On-line conductivity measurement of mineral contamination in water allows reliable and inexpensive monitoring of water quality through the various stages of treatment. In comparison to having to install different analog sensors to cover the total measuring range, a single digital conductivity sensor with integrated measuring circuit can measure from ultrapure to brackish water.
