    • High Performance Bearing Comparison 
      Ronan, Josh; Shoup, Thomas; Perney, Gwenael; Robertson, Chad; Quoix, Bernard; Gelin, Alain (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
      With the increasing demand for high performance gearboxes, larger, faster, more highly loaded bearings are requiring more oil and creating more heat than ever before. This means the lubrication systems must be larger to ...
    • Hybrid Pump: A New Type Of Pump For The Pazflor Deep Sea Project 
      Bibet, Pierre-Jean; Quoix, Bernard; Grimstad, Haakon (Texas A&M University. Turbomachinery Laboratories, 2009)
      Subsea processing gives pump engineers permanent technical challenges due to the comprehensive specifications that often stretch the proven limits of technology. It is particularly true for pumps that have to boost a ...
    • Lifetime of Gas Turbines Hot Section Parts in an O&G Environment 
      Quoix, Bernard; Bellocq, Pablo; Pesquet, Amelie (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      The main driver to define the time between overhauls of a gas turbine is the life of the hot components. For an Oil&Gas operator, a turbine overhaul represents a major cost and therefore is a key point for performance ...
