Life Cycle Costs For Thermal Spray Zinc Duplex Coatings On Long Lifetime Steel Constructions

Product Number: 51322-17803-SG

Author: M. Gagné, O.Ø. Knudsen, K. O. Dahle

Publication Date: 2022

Very often the life of a corrosion protection paint coating system will not meet the design life of the steel structure it is supposed to protect. Decisions about coating selection are usually focusing on the costs for the initial construction, ignoring the certain future maintenance costs. The total cost of ownership includes the initial cost plus the maintenance, operating and finance costs over the life of a structure. Repeated maintenance operations, and resulting downtime, can add significantly to the total cost of ownership.

Life Extension of Offshore Field in the Santa Barbara Channel 1: Simultaneous ICCP Retrofit of Three Jacket Platforms

Product Number: 51323-18978-SG

Author: Sami Abu-Zahra, Omar Rosas-Camacho, Mathew L. Taylor

Publication Date: 2023

$20.00

Three platforms in the Santa Ynez Unit (SYU) field in the Santa Barbara Channel, platforms Heritage (HE), Harmony (HA), and Hondo (HO), were installed between 1979 and 1989, approximately 19 km (12 miles) west of Goleta, California in water depths between 259 m (850 ft) to 365 m (1200 ft). These platforms were previously retrofitted with ICCP sleds which were in decline, requiring additional Impressed Current Cathodic Protection (ICCP) anode output. Therefore, they were all retrofitted with additional ICCP systems in a single campaign to provide a 25-year life extension.

Life Extension of Offshore Field in The Santa Barbara Channel 2: Multi-Objective Optimization of Retrofit ICCP Anode Sled Placement Using Calibrated 3D Simulations

Product Number: 51323-19382-SG

Author: Matthew L. Taylor, Omar Rosas Camacho, Sami Abu-Zahra

Publication Date: 2023

$20.00

The life of offshore jacket structures can be extended up to 30 years towards the end of their design life by retrofits. For larger structures, and in unusual cases, semi-remote ICCP anode sleds are a favorable option compared to sacrificial anode cathodic protection (SACP) due to the high current output from each individual installation, reducing the time to install substantially. Anode sled locations are determined based on site plans, experience, survey data, and equations evaluating “remoteness” or “voltage rise” criteria.

Publication Date: 2023

$20.00

The Santa Ynez Unit (SYU) consists of three offshore platforms and an onshore oil and natural gas processing facility in Goleta, California. The platforms are located between five to nine miles offshore in federal waters. The construction of SYU began in 1976 in the Santa Barbara County in California with the platform Hondo (HO) which, started operations in 1981 to supply the domestic California market.

Life-Cycle Cost Evaluation Of Corrosion Mitigation Strategies In Mining Industry

Product Number: 51322-18146-SG

Author: M. Naghizadeh, Y. Savguira, M. Fatakdawala

Publication Date: 2022

$20.00

An economic evaluation of a project plays a significant role in determining its feasibility. Corrosion is intrinsic to the operation of metallic assets, and the costs dedicated to its prevention and/or its consequences are unavoidable. Different corrosion strategies could be developed to address the project's needs while complying with relevant codes and standards. These various corrosion control strategies are characterized by inherently different capital expenditures (CAPEX) and operating expenses (OPEX). Careful analysis of the cost projections for each of the considered corrosion mitigation strategies is needed for project optimization and improvement of return on investment.

Lifetime Corrosion Control Cost Minimization

Product Number: 51220-265-SG

Author: Douglas Mittlesteadt, David Morton

Publication Date: 2020

$20.00

Most capital projects in the energy market face significant cost overrun issues. There is a real need for innovation to improve productivity; reduce the need for completion on site and to minimize the annual operations maintenance budget. By optimizing the coating specification, we can increase the likelihood of paint completion during the project while increasing productivity and quality.

Lighting Applications for Protective Coatings: The LED Advantage

Product Number: 41211-624-SG

Author: Michael S. Kralik

Publication Date: 2011

$20.00

The use of advanced LED (Light Emitting Diodes) lighting for protective coating applications provides a significant improvement in the efficiency of the process. Better surface and area visibility improves job performance and is critical for compliant coating application and provides a better work environment for the technicians applying the coat.

Aircraft reliability and maintainability are critical to their availability and operation. One of the biggest threats to aircraft availability is corrosion of aircraft systems. The annual cost of corrosion for Air Force aviation and missiles is estimated to be $5.67B dollars, or 23.6% of total maintenance costs for this equipment, and 2.1 million non-available hours. It is estimated that for defense acquisition programs 60 – 80% of the total life cycle cost is associated with the operation and support (O&S) phase.

Lightweight Tomographic Monitoring of Pipe Wall Thickness

Product Number: MECC23-19896-SG

Author: Audun O. Pedersen; Francesco Simonetti; Geir Instanes; Peter B. Nagy

Publication Date: 2023

$20.00

While corrosion and erosion in subsea pipes remains a significant concern, instrumentation has been developed to provide detailed mapping of wall thickness loss. In the mid-2000s the Corrosion-Erosion Monitor was introduced, which utilizes guided ultrasonic waves (GUW) to monitor mean wall thickness loss between non-intrusive ultrasound transducers installed permanently on pipe sections with typical length 0.7 m–1 m [1, 2, 3, 4]. The tomography software package was developed in the 2010s [5, 6, 7, 8] to produce two-dimensional wall thickness maps from the GUW monitoring data.

Line Pipe DC-ERW Long Seam Weld Anomaly Investigation

Product Number: 51324-21182-SG

Author: Luke Jain; Lee Vest; Rick Gonzales; Alex Hudgins; Ransom Stamps

Publication Date: 2024

$40.00

Linear anomalies were discovered during construction activities near to the DC-ERW long seam weld of a 20-inch natural gas pipeline. Magnetic particle testing and phased array ultrasonic testing were applied to characterize the anomalies. Pipe samples were removed from the pipe for additional destructive laboratory analysis. Laboratory analysis included visual assessment, X-ray computed tomography, cryo-fracture, cross-sectioning, metallographic analysis, and scanning electron microscopy. Inspection and testing results indicated that the anomalies were consistent with roller contact marks introduced during pipe manufacturing and did not show evidence of time-dependent growth. Representative anomalies were evaluated using a Failure Assessment Diagram to provide an additional level of assurance. All flaws were found to be acceptable in accordance with general application of API 579 Part 9, Level 2.
