Pipeline Integrity Assessment Project Client: Toltest Engineering Location: Monathan Airforce Base - Tucson, Arizona TechCorr was contracted by Toltest Engineering to perform a detailed engineering assessment on the critical fuel piping system at Davis Monathan Airforce Base located in Tucson Arizona. The piping system is designed to fuel US Airforce Fighter Jets. The engineering assessment was designed in accordance with API 570 procedures incorporating visual inspection of all equipment components, ultrasonic thickness surveys on equipment components, hydrostatic testing of main fuel pipeline, guided wave ultrasonic testing on main fuel line and cathodic protection system audit to assure appropriate level three protection. A detailed engineering assessment was completed following the field data collection phase to develop a corrosion mitigation program. |

Advanced Aboveground Storage Tank Inspections – In-Service Robotics This paper describes the tank inspection requirements (such as New Source Performance Standards [NSPS], 40 CFR 60), conventional inspection techniques (out-of-service, manual, confined space entry, and visual), advanced inspection technologies (in-service robotics), benefits derived from using these advanced technologies, and the status of approval of these technologies by regulatory agencies. The authors also review the unique challenges and implementation circumstances associated with advanced inspection technologies. Finally, the authors present a pilot study currently in progress for the application of advanced inspection technologies to an Internal Floating Roof (IFR) tank subject to NSPS Subpart Kb (Standards of Performance for Volatile Organic Liquid Storage Vessels) requirements. |

PDVSA Pipeline Integrity Assessment Project Client: PDVSA Gas Anaco (National Oil Company of Venezuela) TechCorr was contracted by PDVSA (Petroleos de Venezuela S.A.) to perform a baseline assessment on roughly 500 kilometers of production and transmission assets associated with PDVSA Anaco operating division. The pipeline diameters ranged from 2" up to 36" in diameter both buried and above ground. These pipeline transported natural gas between production fields utilized in the gas injection process as a secondary recovery technique when pressurizing oil reservoirs. Failure of these pipelines was estimated to affect over 200,000 barrels of oil production daily as reservoir pressure could not be maintained. |

Pipeline External Corrosion Direct Assessment (ECDA) Project Client: Chevron Global Solutions Location: Maracaibo, Venezuela TechCorr was contracted by Chevron Global Solutions to perform an ECDA (External Corrosion Direct Assessment) and ICDA (Internal Corrosion Direct Assessment) on a 26" diameter 28.6 kilometer buried pipeline system. This is the only pipeline system between the Chevron Boscan production field and Bajo Grande loading terminals. Failure along this pipeline would cut off nearly 123,000 barrels of oil per day to markets world wide. |

Spider Wrap Light The leak was at 120 psi and the hole was about 1/7th of an inch. Mr. Shahid Raza Imam who is a certified SW Applicator first applied pressure sealing rubber tape to encapsulate the leak area. Then applied 6 wraps of water activated fiber glass tape on the pressure sealing tape with 4” projections on either side. The leak was contained and all concerned people including Field Manager Mr. Saleem Lutfi, Technicians Khalid Saleem and Ghulam Hassan lauded the product and service. |
