Aging facilities drive rising maintenance costs; need for cost effective solutions

Energy companies are facing rising maintenance costs as decades-old hydro plants face issues created from aging equipment. Rusting, out-of-round and pitted shafts are among the problems contributing to frequent downtime and thousands of dollars in unbudgeted maintenance costs associated with ongoing emergency repairs, equipment replacement and lost revenue. The implications of these and other age-related equipment issues go beyond hard …

Lignum-Vitae provides extended life to 1920s era turbine.

The Challenge The New York Power Authority (NYPA) approached Lignum-Vitae North America (Lignum Vitae) for a solution for its bearing challenges on vintage GE turbines at its facility. The turbines, which used phenolic bearings installed more than 60 years ago, were experiencing significant run out and vibration issues. The bearing issues led to an unstable plant that was incapable of …

Why is Lignum-Vitae the bearing of choice for over 100 years?

Is it a coincidence that every plant listed on the Hydro Hall of Fame started life on lignum-vitae bearings, we think not! As the bearing of choice for all Hydro Hall of Fame recipients Lignum-Vitae also holds the distinction of maintaining the Mechanicsville plant as the oldest continuously operating three phase hydro in the world since 1897! To keep pace …

Will EPA Mandated Plastic & Composite Bearing Regulations Be Next?

Man-made products have provided substandard bearings for Hydro Power Plants. Problems arise from these plastic and composite alternatives such as increased maintenance cost and environmental issues.  “What toxic materials or chemicals are used to manufacture these bearings?” In addition, new studies reveal the environmental impact of small microplastic particles leaking into our water supply may be detrimental to fish. With …

The factors that affect cleanup of an oil spill cost are complex

While the final costs of cleanup can vary and are difficult to quantify, there are often lawsuits and fines associated with the spill, along with an increase in liability insurance rates. When an oil leak or spill occurs, it could take hydro operators months of constant clean-up activities, diverting its valuable human and financial assets from production. Potential lost “opportunity …

Lignum-Vitae is leading the way back to a simple water lubricated future.

Timing is everything especially when government compliance and environmental needs merge together. Balancing these needs while delivering a reliable energy source can be a challenging and complex task unless you keep it simple. Introducing “new products” such as plastics and composites can introduce unintended consequences such as instability by requiring a gap between the shafts and bearing to avoid wiping …

How does an old technology restore performance to an existing Hydro Plant?

The Hydro Plant was reaching the end of its useful life after more than 45 years of operation. The energy company contracted Voith to modernize the Hydro Plant. Voith is a global leader in the Hydro industry and has access to a wealth of knowledge when it comes to comprehensive engineering solutions. Component expected life expectancy analysis is an important …

USACE settlement in Columbia River lubricant suit paves the way for changes to come in hydro.

Change comes slowly – that is, unless it comes in the form of environmental litigation or federal mandate. In Columbia Riverkeeper v. U.S. Army Corps of Engineers, Case No. 2:13-md-02494-LRS (E.D. Wash.), both converged to tighten the Army Corps’ policies and practices for handling hydro generation lubricants in order to prevent oil from getting into the water supply. In August …

Why should Water Lubricated Bearings be the center of every Hydro Power Plant?

It’s simple… the environment is the most valuable asset we have and water lubricated bearings offer a safe, sustainable solution for Main Guide Bearings. The United States started out with Water Lubricated Bearings that have decades of proven performance and longevity without the risk of oil spills, high Insurance cost, lawsuits or public relations nightmares.
