Dr Ninh Nguyen

Principal Consultant 

Professional Background

3D finite element modelling of turbine and boiler components subjected to complex transient mechanical-thermal stresses and fatigue, creep or creep-fatigue damage, modelling of contact and vibration problems. Plant life modelling of creep-fatigue damage, rates of crack growth and defect tolerance assessment in accordance with industry advanced structural integrity procedures such as BS-7910, British Energy R5-R6 and API-579.

Areas of Expertise

  • Advanced finite element modelling and analyses (utilizing commercial software such as ANSYS et al.) to support failure investigations (inc.court cases), design verifications and defect-tolerance fitness-for-service, plant life assessment in power, petrochemical, structural, infrastructure and military industries.
  • Development a suite of in-house standard based program/models for applications e.g. FATCREAM for creep-fatigue defect-tolerance fitnessfor-service and life assessment of range of cracked components.
  • Project manager for number of consulting and R & D projects.

Relevant Project Experience

  • Performed numerous finite element mechanical-thermal stress analyses, structural integrity and Defect Tolerance Assessments (DTA), fitness-for-service, creep-fatigue assessments for power plant components including turbine and boiler components for power generation, petrochemical, structural, smelting, infrastructure, automotive and military industries (e.g. NRG Gladstone, Synergy, CS Energy, Stanwell PS, Alinta Energy, TRUenergy, Loy Yang, Energy Brix, Esso,Santos, Temco, Alcoa, Telstra, Holden, Pall corp. et al.).
  • Heat transfer and electrical-thermal analyses for design verification of smelter furnace refractory (Temco), failure investigation of the furnace electrodes for smelting industry (Temco & Alcoa), piping analysis (TRUenergy), piping tee design and assessment (Synergy, Esso) and concrete floor modelling to determine load capacity (Telstra).
  • Developed an in-house standard-based (R5-6 & BS7910) creep-fatigue life assessment package i.e. FATCREAM (FATigue CREep Life Assessment Method). Updating this tool with most recent technical advances and its application for the remnant life assessment of boiler & turbine components and pressure vessels for numerous power generators and other industries.
  • Project leader for developing a new robust DTA product for Fitness-For-Service & Defect Tolerance Assessment of cracked components.
  • WTIA Panel 14 "Arc Physics" member and contributed number of technical papers to WTIA National and International Proceedings and Welding journal since 2000.
  • Author of the engineering reference "Thermal Analysis of Welds", 2004, UK WIT Press and a number of articles in professional journals and conference proceedings.
  • Project leader on "Investigation of creep-fatigue effect on the remaining life of the power plant components", 1 year BCIRP R&D project, 2001-2002.
  • Project leader on "Investigation of ALCOA bolted joint connections to improve electrical efficiency", 1 year SECV & ALCOA joined R & D project, 2005-2006.
  • American Welding Society Award for significant contribution on Welding Research on Maritime Welded Structures, 1999.
  • Contribution to AWS Welding Standard and Handbook.


  • Bachelor of Engineering (Mech. Welding, Hons), Slovak Technical University, Slovakia, 1984.
  • Masters of Engineering (Mech.), AIT, Thailand, 1991.
  • Doctor of Philosophy (Fatigue of Welded Structures), Adelaide University, Australia, 1996.

Professional Associations and Memberships

  • Member of WTIA
  • Chartered Material Professional with Materials Australia
