FLARE GAS PIPING VIBRATION
Gyorgy Szasz, Staff Consultant, Stress Engineering
A fare gas piping vibration problem that was holding back production on the Petrobras P-58 FPSO will be discussed in this presentation.
The vibration was measured and studied by a team of engineers, and a temporary solution was implemented. Recommendations for a
permanent solution were also provided.
Dr. Szasz is a Staff Consultant at Stress Engineering Services, Inc. He has more than 18 years of experience in vibration testing and analysis,
instrumentation and signal processing. He is a certifed category IV vibration analyst.
CHALLENGES OF DESIGNING, FABRICATING, AND INSTALLING DEEPWATER FIXED JACKETS
Gary Epperson, Structural Engineer, Oil Field Development Engineering
The Walter Oil & Gas Ewing Bank 834 development consisted of a fxed platform in 1,186 feet of water. While considering existing
technology, this was the deepest fxed jacket installation in the Gulf for many years. This presentation will discuss some of the inherent
challenges in design, fabrication, and installation for this type of development. Also examined will be the under and/or over-reliance on

COMPARISONS BETWEEN COMPUTATIONAL FLUID DYNAMICS AND
WIND TUNNEL TESTING FOR MODUS
Jorge Martinez, President, JLMLLM Consulting
Wind Tunnel Testing and Computational Fluid Dynamics (CFD) are two tools that can be used to obtain wind loads in MODUS. A
comparison of the tools, their advantages and disadvantages together with some lessons learned is being presented.
Jorge Martinez, President of JLMLLM Consulting has 30 years’ experience in low speed wind tunnel testing. As the Director of the wind
tunnel facility, Martinez helped developed test procedures for the wind load evaluation in MODUS. Since his retirement, he has continued
his work and is working with the Society of Naval Architects and Marine Engineers (SNAME) in the proposed new guidelines for wind
tunnel testing. The work with SNAME includes the understanding and comparison of CFD to wind tunnel results.
