Ability Summary:

Dr. Hillary Yin is an expert in fracture-mechanics based engineering critical assessment (ECA) and fitness-for-service (FFS) assessment of welding flaws and other cracks found in structures and equipment used in the oil and gas industry. She has developed broad metallurgical knowledge through 30 years of experiences in oil/gas and tools manufacturing industries. She is not only strong in mathematical modeling and analysis, but also very skilled in experimental lab work. Her knowledge and skills on the experimental fracture and fatigue testing (i.e., J-test, FCGR and S-N fatigue curves in sweet and sour corrosion environments) had added great values to her client's businesses. She has trained several young engineers from several operating companies.

During her 12 years of service with Stanley Black & Decker as the engineering manager for product test lab, Dr. Hillary Yin also took the responsibilities of the metallurgist and provided scientific data and technical justifications for improving manufacturing processes such as cold forming, hot forging, heat treatment, Ni-Cr plating and failure analysis of field returns. She provided the most cost-effective steel grades for making high quality hand and power tools. She has been serving on ASME B107 committee and SAE EG-1B committee for writing industry standards.

●Developed fatigue life analysis procedure for assessing pressure cycling induced fatigue life for ERW pipelines. Implemented a cyclical index methodology for screening fatigue severity of ERW pipelines

●Reviewed and analyzed over 300 fracture toughness J-tests of historical ERW welded pipes. Built a fracture toughness database for ERW pipes.

●Guided and witnessed sour and sweet service fracture mechanics testing of pipeline materials (J-tests, FCGR and S-N fatigue curve tests)

●Metallurgical failure analysis of broken components, such as offshore gas turbines.

●Major clients included ExxonMobil pipeline, BP Thunder Horse, BP Mad Dog Phase 2, Chevron Angola Project, Ameriforge/Taper-Lok, Enbridge Pipeline, Keystone XL/TransCanada Pipeline, Energy Transfer Pipeline, Spectra Pipeline, Modec, etc.

5/1/2000 - 6/1/2012 Engineering Manager and Metallurgist, Product Testing Lab - Stanley Black&Decker

Industrial Tools Group, 12827 Valley Branch Lane, Dallas, TX 75234

●Expanded Stanley’s product test lab in Dallas from a simple mechanical testing lab to a multi-functional engineering test center by adding new lab equipment for metallurgical testing, metrology measurements, new multi-station cycle life torque testers, and impact testing stations. The upgraded multi-functional test center was a critical player supporting the R&D new product development, reverse engineering of competitor’s products, products and tooling failure investigation and production QA/QC inspection.

●Responsible for product qualification testing of all mechanics tools manufactured in the Stanley’s plants in Dallas and in Asia, as well as the sourced products manufactured by outside vendors for the Stanley’s industrial product lines (Proto, MAC, Stanley, Blackhawk brands, etc.).

●Performed failure/metallurgical analyses of the field returned products from customers.

●Performed comprehensive evaluations of competitor’s products. Obtained their dimensional analysis data, component materials and manufacturing processes (e.g., investment casting, MIM, forging, heat treatment, and plating) used for the competitor’s products.

●Recommended the most cost-effective and reliable tool steel grades for making high quality hand tools and power tools for Proto and MAC brand industrial tools.

●As a certified Six Sigma green belt, led my teams completed multiple projects for improving production efficiency. Developed a more cost-effective sampling plan based on Weibull statistical methodology for our improved product quality control process.

●Managed the product test center according to ISO 9001 standard, and maintained ISO 9001 certification for the lab.

●Actively participated in SAE EG-1B and ASME B107 committees in writing industry standards for tools.

10/1/1995 - 4/30/2000 Senior Staff Engineer – Mobil Oil Corporation (Currently ExxonMobil)

Mobil Exploration & Production Technical Center (MEPTEC - Upstream)

Mobil Technology Company, 13777 Midway Road, Dallas, TX 75244

●Built the MEPTEC’s Materials Performance Testing Laboratory to conduct the experimental investigation of sulfide stress corrosion cracking (SSC) and other forms of environmental cracking in downhole tubulars, oil & gas pipelines, and gas treating equipment. Prepared the proposals and budgets on various R&D and technical service projects, and led the team to accomplish the tasks efficiently and timely. In addition to the standard industrial tests per NACE standards, developed the Mobil’s innovative procedure for fracture mechanics testing of metals (i.e., environmental J-integral testing) in high-pressure, high-temperature CO2/H2S bearing environments that were simulated based on the service conditions for Mobil’s oil & gas producing and processing equipment to determine more accurate threshold toughness for environmental cracking. The test results were used to develop the Mobil’s LRFD for downhole tubular and pipelines.

●Using “fitness-for-service” methodology, performed fracture and fatigue analyses of heavy wall pressure vessels and offshore structures containing welding flaws to determine their mechanical integrity, safe remaining service life, and to avoid unnecessary repair.

●As a Mobil’s key metallurgical engineer and FEA specialist, closely worked with rotating machinery equipment manufacturers and vendors in numerous comprehensive failure investigations to identify the root cause of each failure of several Mobil’s high-pressure gas injection compressors and high temperature gas turbines. The projects typically involved reviewing the data/results from FEA stress analyses, computational fluid dynamics analyses, and metallurgical examination of failed parts. We found that about 90% of rotating equipment failures were caused by inadequate design and/or poor manufacturing quality.

●Actively involved in MEPTEC’s QA projects on purchasing downhole tubulars for Mobil wells. Supervised outside laboratories on conducting SSC tests on tubular materials and performed statistical evaluation of the material’s property data to assure the tubular’s quality meet MEPTEC’s specifications for use in H2S containing wells.

●Performed in-house metallurgical failure analyses of failed components from Mobil’s E&P operating units (gas plants, offshore platforms, pipelines).

●Actively involved in joint industry projects and API technical committee work to develop new API standards. Provided technical training classes to Mobil’s drilling and producing engineers on application of fracture mechanics in casing/tubing design for H2S/CO2 containing service and provided technical training classes to Mobil’s E&P and M&R engineers on “fitness-for-service” assessment of existing equipment used in refining and gas processing plants.
