France
Over 16 years skill on flowline global analysis (lateral buckling, pipe walking, expansion, and relevant coupled analysis), as well as on Engineering Critical Assessment (ECA) for all systems (flowline, riser, structural components…). Over 18 years skill on FEM of complex mechanical systems. Focused, since January 2004 (with SAIPEM), in deep water Offshore field. Mainly involved in large UFR projects as leader/specialist engineer. Provide wide range of consultancy services to various other projects, bidding and R&D, related to design, stress analysis, including integrity issues, materials/welds issues, damage mechanisms evaluation, defect criticality assessment, fitness for service, design life extension. Motivated, creative with a strong technical & theoretical background and good analytical approach to solution delivery and commitment to quality. Oriented to provide/developpe tangible needed skills. Mission-aligned. Good working attitude to follow up, to train and to do grow-up the team, as well as interact with others specialists and others disciplines with the purpose to improve knowledge and do more and better together.
● Reviewed design and fabrication documentation for Main Steam Lines (MSL), Main Feedwater Lines (MFWL), High Integrity Components (HIC), and instrumentation lines in nuclear plants. ● Two-year assignment on the Flamanville EPR (FA3) nuclear power plant project, France: delivered structural integrity consultancy and recommendations to support the final main welds reparation phases of MSL - MFWL, and final instrumentation lines fabrication phases. ● Developed cost-effective solutions for the re-assessment of multiple non-conformities detected in welded joints of critical piping systems. ● Supported thermal fatigue optimisation of welded joints exposed to severe through-thickness temperature gradients. ● Estimated pre-strain levels induced in auxiliary system piping sections following repair and maintenance interventions. ● Contributed to R&D activities: - Proposal to enhanced Paris’ law for more accurate fatigue crack growth predictions. - Proposal to enhanced mechanical material properties characterization for more accurate structural integrity assessment. - Investigated root causes of stress corrosion cracking (SCC) in welds of the Safety Injection System.
● Review of flowline design activities, and advice relevant technical solutions/ recommendations via cost-effective design solution. ● Strain based assessment via standard FEM and advanced FEM models (such as Continuum Damage Mechanism model using Bonora’s damage formulation) of flawed or unflawed structural component/weld joint/pipe which experience large strain condition (such as rigid pipeline reeling installation, extreme events, local dent on pipeline or on structural component). ● multiaxial fatigue assessment (DangVan criterio) to largely improve fatigue endurance prediction of structural component/joint/pipe. ● material characterization to be used for advanced numerical model in structural integrity assessment of flawed or unflawed component/weld joint/pipe (such as assessment of local and global plastic failure accounting for the evolution of structural constrain and load triaxiality). ● Build, follow-up, train and grow-up of the Structural Integrity team ● Propose and lead the R&D activities of the Structural Integrity items. ● Review of the interdisciplinary engineering activities (design, installation, technology) ● Witness the full-scale as well as small-scale test for numerical model validation purpose.
