Research & Innovation

BETA's long term commitment to R&D has been one of our success factors.

Our annual R&D budget is significant. Research projects include vibration and dynamic modeling, acoustic (pulsation) simulation, post-processing analysis software, service methodologies, and products that control vibration. As a result of new innovations (see below), our clients benefit from novel solutions, more accurate recommendations, and faster results.

2 BETA Sponsored Research

BETA funded and managed (in-house) research projects include:

  • Small-Bore Connections (Branch Connections) – Field vibration and stress testing for gas and liquid systems; design approaches for small-bore piping subject to vibratory loads.
  • Mechanical/Acoustical Analysis (Pulsation Analysis) – FEA modeling and field based research to develop extensive knowledge base and library for stiffness, damping, acoustic modeling, performance modeling, forced response predictions, field troubleshooting, and other related topics. Results were used to enhance BETA’s MAPAK software simulation package and field testing methodologies.  
  • Torsional Vibration – Field and simulation modeling of torsional vibration, including accurate field calibrated design software.
  • Structural and Foundation Dynamics – Field based testing on land based foundations and offshore production platforms (and FPSOs), used to enhance BETA’s Dynamic modeling software.
  • Piping Vibration – Field and design testing on piping support, restraint design, vibration absorbers, FIV analysis, and other related piping vibration issues.
3 Mechanical Acoustical Package (MAPAK) Simulation Software Suite
Simulation software development in the 1970s - Gordon Sun
Simulation software development in the 1970s. The source code for each simulation was punched on soft tape (therefore the term "software"), the tape was then fed through the computer and output to a dot-matrix printer.

Bottle shaking forces

BETA led the industry in vibration analysis and pulsation control in piping systems and developed North America’s first digital simulation program (1973). After continual enhancements, a major upgrade to pulsation analysis was introduced to the industry (1998) using our non-linear Time Domain algorithm.

The Time Domain Solver™ software tool is used in pulsation (acoustic) analysis, transient fluid flow, torsional analysis, and mechanical vibration analysis. This proprietary software package offers more accurate analysis when compared to commercially available programs. Read more

Some of the features of this program include:

  • Analysis of unlimited number of nodes and operating conditions
  • Accurate static and total power losses in dynamic fluid systems
  • Superior accuracy at high frequency
  • Expanded meter error analysis
  • Refined compressor bottle sizing programs
  • Increased accuracy for high pressure gas, low compression ratio, or large cylinder bore systems

In 2007, BETA introduced the first DataMinerTM post processing tool to help improve the analysis and evaluation of pulsations, forces and vibration across the entire operating envelope and piping system. Many new enhancements are introduced each year to this proprietary analytical tool. 

DataMiner is used on almost all projects to:

  • Assess pulsation, forces and vibration across different operating conditions
  • Comply with applicable guidelines
  • Test the sensitivity of skid piping to various configurations of off-skid piping. Very useful when off-skid piping details are unknown.
  • Estimate total pressure drop and power loss across entire systems (cooler, piping, vessel, etc.) and at all operating conditions
  • Compare alternative solutions to determine the best overall recommendations.

Mechanical Vibration Modeling  for High Speed Compressors
BETA has ongoing projects to improve the mechanical and vibration solutions for high speed compressors.R&D includes:

  • New approaches for accurate Finite Element (FE) modeling
  • Compressor frame assessment using “super element” models
  • Damping of mechanical systems
  • Field testing to confirm accuracy of software models
  • Improved solutions for variable speed units (engines or VFDs)

2007 DataMinerTM post processing tool

2012-2014  Industry funded research for the Gas Machinery Research Council (GMRC). See above for list of projects.

2013-2014  In 2013, BETA Vibration Absorber was developed for trial evaluation. Based on the success of field installations, a commercialized product was developed and released in 2014.

2011-2013  Developed DataMiner2TM program building on the original DataMiner™ post processing tool, first introduced in 2007. More points over the operating map can be accurately measured in a much shorter time, helping equipment operators and owners make better and more informed decisions.

2009  Pioneered the System Performance Model™ (SPM™) program in collaboration with
ACI Services, Inc. For the first time ever, owners and packagers are provided with crucial information about compressor performance across the whole operating map. This service evaluates different alternatives resulting in improved reliability, safety, and profitability. Originally geared to optimizing pipeline compressor stations, this service is also ideal for midstream, injection-withdrawal, and other larger compressor applications.

2008  Partnered with M2M Data Corporation (M2M) to develop Intelligent Machinery Service, or iMA™ asset management tool. This is a breakthrough new multi-tiered machinery diagnostic and optimization service, representing the most cost-effective, real-time monitoring, analysis, predictive maintenance, and optimization solution available. Among the benefits are increased throughput, optimized performance, lower cost of maintenance, and emissions monitoring.

2007  Introduced DataMiner™ post processing tool, an innovative method to "mine" valuable results across many different operating conditions, speeds, or designs. This tool enables our experts to optimize the compressor design resulting in lower horsepower losses (operating costs) and improved reliability. End users realize more efficient units and lower costs.

2006 B-ProbeTM inspection tool redeveloped with Dynalco

2006  Re-developed the B Probe™ inspection tool in partnership with Dynalco for sale to the market. Has enhanced performance and capability and still the only non-intrusive inspection tool of its kind to evaluate the condition of power cylinders, wrist pins, and con rod bearings on spark-ignited and diesel engines. DynaProbe uses BETA's B-Probe technology.

2005  Release of MAPAK™ modeling program version 22 with enhanced modeling of meter error, dynamic pressure drop, time domain analysis and dual cylinder nozzle gas passages, compliant to API 618 5th Edition guidelines. Celebrated over 1900 acoustical analysis projects to minimize vibration problems on machine systems.
