  • 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

  • MPR Develops Fail-Safe Controls for Critical Mission Equipment

    Chilled Water Automation System

    The Navy needs to improve the survivability of chilled water systems to help prevent vital ship functions from shutting down due to loss of cooling when combat damage occurs. The automation to recover the system from damage needs to be highly survivable. The Navy needed to select an economical system developer with unique expertise in fluid control systems and survivability, and the ability to integrate with the existing shipboard control system.

  • Nuclear Hydrogen Initiative is Recognized for Best Program Management

    Nuclear Hydrogen Initiative Program Management Support

    The Department of Energy's (DOE) Nuclear Hydrogen Initiative (NHI) is a key part of the nationwide efforts to mass produce an energy source that is economical, environmentally safe, and independent of foreign sources. The Nuclear Hydrogen Initiative is developing the technology to efficiently and cleanly produce large quantities of hydrogen using nuclear power as the energy source for the process. Managing the technically and geographically diverse Government and commercial activities that comprise the Nuclear Hydrogen Initiative is a significant challenge. Read More

  • MPR's Smart Valve Technology is Installed In DDG 51 Class Ships and in the Advanced DDG 1000 to Improve Survivability

    Survivable Systems Development and Design

    Several key factors are driving the Navy's need to apply new technology to make ship systems more survivable: -Weapons are more lethal. -Modern mission systems are more dependent on support from integrated ship systems to provide power, cooling and other vital support. -Ship manpower must be reduced to make future operations affordable; this requires moving from manual to automated recovery from damage. Meeting the challenge of creating more survivable systems requires innovative approaches to ship systems survivability. Read More

  • MPR Helps Major DOE Project Start Construction on Track

    Department of Energy Mixed Oxide (MOX) Fuel Fabrication Facility

    Reducing the amount of weapon grade nuclear material in the US and Russia is a key part of reducing the threat of nuclear weapon proliferation. The US and Russia agreed to jointly dispose of tons of nuclear warhead material by "burning" it in nuclear reactors, thereby rendering the material unsuitable for use in weapons. To accomplish this, the warhead material must first be processed into Mixed Oxide Fuel (MOX) that can be used in a nuclear reactor. The design and construction of the MOX Fuel Fabrication Facility (MFFF) for safely processing this hazardous material requires the successful integration of several technical disciplines, including: HVAC, Electrical/Instrumentation and Controls, Seismic/structural, Chemical and safety systems, Glovebox mechanical and electrical design, and Glovebox automation and software design.

  • MPR Designs Solution for Valve In-situ Repair, Saving Plant Over $10 Million, Receiving Top Industry Practice (TIP) Award

    Crystal River Unit 3 Nuclear Energy Complex DHV-3 Repair

    The Crystal River 3 Nuclear Energy Complex, in Citrus County, Florida, was experiencing chronic leakage in an un-isolable valve in the decay heat removal system. The valve is an integral part of the closed-loop coolant system and shutting down the reactor to make the repair would have cost the plant millions of dollars. Repeated unsuccessful attempts were made to repair the valve and prevent further leakage. Read More
