Case Studies

  • Continuous Blood Glucose Monitor

    An MPR client desired a medical device capable of automated glucose monitoring using a conventional in-line intravascular (IV) catheter. The device was to be designed specifically for patients undergoing intensive insulin therapy in critical and intensive care units. It was required that the monitoring system would automatically sample the patient's blood, test the blood for glucose levels, and reinfuse the blood into the patient, ensuring the entire fluid pathway was kept clean for extended periods of time (up to our days). In addition, the device was required to operate in an automatic unattended fashion and report any abnormal readings. Read More

  • MPR Develops Reliability Centered Fleet Operation & Maintenance Budget Forecast

    The client desired improved unit reliability and power production to achieve management defined objectives when faced with changing expenditures to match corporate goals. Read More

  • Reliability Improvement in the Hydrocarbon Process Industry

    Our client, a large United States based petrochemicals company, wanted to extend the interval between refinery compressor train maintenance outages from 8 to 10 years. Read More

  • MPR Re-powers NRG Long Beach Generation Facility Providing Critical Power to Southern California

    NRG Long Beach Generation Facility

    In December 2006, NRG initiated a $100 million emergency re-powering project to restore the Long Beach Generating Station to commercial operation. The specific objective was to re-power four of seven combustion turbines, which had been idled since 1998, prior to August 1, 2007 in order to meet the summer peak generation period. Read More

  • MPR establishes predictive tool for evaluation of steam transients

    Texas City Green Power LLC - Owner's Engineer

    MPR provided engineering and on-site project management assistance for the development of a new cogeneration facility at a refinery. The purpose of the new facility was to improve the efficiency of the power and steam generation, support additional loads within the refinery, and provide merchant power for the grid. In addition to the typical MPR owner's engineer scope to oversee EPC contractor technical and commercial performance, the complexity and extreme reliability requirements on the steam supply from the cogeneration facility required detailed technical evaluations to identify cost effective improvements in equipment and control system capabilities.

  • MPR Supports Fast Track Gas Conditioning System Installation

    Brazil Combined Cycle Power Project - Owner's Engineer

    MPR Associates was selected to be an owner's engineer for a combined cycle power plant in Brazil. In addition to the typical MPR owner's engineer role to provide technical and commercial oversight of the contractor's engineering, procurement and construction activities, MPR was requested to manage the fast-track design and installation of a $40M gas conditioning system. The system was needed when it was recognized late in the project that the natural gas, provided from Bolivia via pipeline, did not meet the gas turbine specifications. The client also determined that there was a significant local market for Natural Gas Liquids (NGL) that could be extracted from the pipeline gas. Therefore, the project was to be designed to extract NGL products to specification and to enable loading of tank trucks for delivery of the products. Read More

  • Keeping Wind Turbines Turning Reliably

    New World Generation Drive Train Technology

    MPR has assisted New World Generation (NWG) in the development of a new wind turbine drive train technology aimed at addressing outages and unreliable performance. The problems with wind turbines are due to damage to drive trains, often manifested as failed gearboxes. Other significant contributors to these failures also include torque excursions during operation and drive train wear when the WT is not in service. Read More

  • Root Cause Investigation of Multiple Failures of a Large Dual-Fuel Engine

    Bangladesh, Floating Dual-Fuel Power Barge

    MPR received a request from the plant owner of the world's largest floating dual-fuel power barge in Bangladesh to conduct an independent root cause investigation into successive failures of one engine. The owner was concerned that the engine, which had been rebuilt one week earlier, had failed again. The 18-cylinder, 20,000 bhp engine is the prime mover for one of eight 15-MWe units, and electrical power already in short supply in the country had become even more scarce. This failure was a more serious break down involving two pistons and connecting rods being ejected from the dual-fuel engine's crankcase. One connecting rod was bent more than 45 degrees and the second connecting rod, along with several pistons and cylinder liners, was fractured. Read More

  • Navsea Client and MPR Receive DOD Standardization Award For the Self Contained Breathing Apparatus (SCBA)

    MPR Helps the Navy Introduce the SCBA into the Fleet

    The Navy needed to replace the WWII vintage oxygen breathing apparatus, and the existing program to develop a replacement for the oxygen breathing apparatus was not succeeding. Read More

  • MPR Leads the Navy Team to Create Intuitive Display Guidance to Improve Operator Performance and Reduce Cost

    Human Systems Integration - Common Presentation Layer (CPL)

    Existing guidance for Navy shipboard displays has been very general, requiring developers to create their own unique guidance resulting in shipboard operators having to work with multiple interfaces, and sometimes without good human factors features in the displays. As a result, display development and training costs have been high and operator performance is not optimized. Read More
