Research2  Update on BETA Research and Innovation

This is an update on some of BETA's internally funded projects and those funded by the Gas Machinery Research Council (GMRC).   

 

BETA Developments

Vibration Pipe Clamp Developments include new products that solve vibration issues and new software capabilities that   directly benefit our productivity. READ MORE 

     

Pipe Clamp Designs for Vibration Service BETA's engineering has resulted in a portfolio of pipe clamps that are used in vibration loads and can address thermal issues as well. These field-proven clamps are now utilized on a wide range of projects. READ MORE 

BETA Vibration Absorber 

Vibration Absorber As a result of recent research, BETA offers this solution to address resonant vibration issues on existing compressors, pumps, and piping systems. Field testing is complete and the products are now being applied to challenging field issues. READ MORE  

 

Asset Vibration Integrity Database This database, based on years of development, is used for facility-wide vibration assessments and Asset Integrity Management (AIM) Programs. Effective management of vibration risks requires this type of tool and BETA's approach provides significant advantages for owners and operators during design, inspections, and operations.

 

Troubleshooting with DataMiner? Post Processing Tool BETA developed a successful data mining processing tool to greatly improve the efficiency of a design project. Thousands of data points can be quickly assessed and evaluated to better understand vibration risks - saving owners and operators time and money. Later in 2015 BETA will release Troubleshooting DataMiner, which provides the same benefits for field vibration data. This software eliminates weeks of post processing time and allows BETA's analysts to quickly and more accurately pinpoint risk areas and problems.  

   

Gas Machinery Research Council (GMRC) 

Predicting Power Loss In Compressor Manifolds (Phase 2)

This project defines a new approach to accurately calculate the dynamic losses, and other important consideration when sizing a compressor. READ MORE 

 

Damping Solutions Testing is complete and a number of new solutions are identified to help manage resonance and vibration. READ MORE 

 

Pipe Support Stiffness Piping designs currently assume a "stiff" support. This project confirms that this is a poor assumption, and provides much more realistic stiffness assumptions for piping systems. These results will benefit all new piping designs. READ MORE 

 

Torsional Effect of Motor Magnetic Field This project is defining a method to address the stiffness and damping due to the motor's magnetic field across the air gap. This affects the torsional stresses in a motor-compressor system. READ MORE 

 

Mechanical design for PAN system BETA leads the mechanical design and testing for this significant project. READ MORE 

 

Other Research

For the API 688 committee, European Forum of Reciprocating Compressors (EFRC) and other standards groups, BETA is providing a draft standard for evaluating vibration on Small Bore Connections. This builds on our field research program, and past technical work. READ MORE 

Expert3  Ask the Expert: Piping Vibration Specifications and Approach

Piping vibration, including fatigue failure, is an ongoing headache in our plant. Whose responsibility is it to prevent piping vibration problems throughout a facility?  

 

The ownership of vibration problems on process piping is a common issue for the plant owner. At the design stage, machinery packagers usually consider vibration within the skid or package boundaries and do not consider the effect of both mechanical and acoustic excitation forces on the connected piping. Numerous excitation mechanisms resulting from flow through the piping itself, such as turbulence and vortex shedding, are frequently ignored in the original piping design as only static  Refinery loadings are considered.

 

At the operational stage, 20% of all hydrocarbon releases are due to fatigue failure, yet this issue is overlooked by integrity inspection programs that concentrate on corrosion and material degradation. If the rotating, static/piping, structural, and integrity disciplines are not working closely together, these potential design gaps can result in fatigue risks going unnoticed, leading to potentially catastrophic results.

 

Vibration is a plant-wide issue and can be managed using a risk-based approach. It is typically included as a design requirement in new plants and can be assessed on a plant-wide scale through the use of industry accepted guidelines such as the Energy Institute Avoidance of Vibration Induced Fatigue Failure (AVIFF) Guidelines.

 

BETA is increasingly working with the integrity disciplines in managing this issue and provides a program that easily integrates into owners' existing integrity management plans to provide measurable reductions in fatigue risk. BETA's program considers all excitation mechanisms across all areas of the plant to provide a complete solution to mitigate reliability and integrity vibration risks.

 

More information on providing an integrated approach to managing vibration risks can be found on our website: An Integrated Approach to Manage Vibration Risks

Surge4  Challenges with Surge Control Studies 

Centrifugal Compressor
It is well known that in certain situations, a centrifugal compressor system could go into surge. What is less well known is why specific surge control valves and piping characteristics still allow severe surge events to occur, and how to best ensure these situations are properly addressed in a surge control design.

BETA's recent article, written by Kamal Botros and Kelly Eberle in the January-February 2015 issue of COMPRESSORtech2 magazine provides an example of how incomplete analysis could result in costly surge events and the best way to prevent them.

Optimized Skid Design for Compressor Packages

This article, one of the top ten downloaded articles in 2014 in COMPRESSORtech2 magazine, highlights the issues involved in skid design for vibration-related loads (compressors and pumps). When designing a structural steel skid (baseplate) for a compressor or pump package, the design must balance stiffness, mass, and cost. High stiffness will help avoid alignment problems due to skid deflection during transportation and installation. Heavier skids tend to have lower overall vibrations, but can have high deflections when lifted. The challenge when optimizing the design is to know where steel can be added or removed to maximize the stiffness and minimize the costs. READ THE FULL ARTICLE
