Cathodic protection within narrow gaps of offshore wind turbine foundations

Product Number: 51320-14750-SG

Author: David Buxton, Petra Ernst, Gareth John, Tom Wewer

Publication Date: 2020

$20.00

Cathodic protection (CP) is routinely applied to the external surfaces of offshore wind turbine monopile foundations to minimize corrosion. When the monopile internals are free-flooding, and therefore also exposed to oxygenated seawater, again, cathodic protection may be applied. In cases of unplanned water exchange through cable entry seals, a small additional surface area, in a gap between the seal and the ‘cable entry hole’ through the steel monopile is then exposed to flowing seawater. Cathodic protection calculations were undertaken to assess whether protection (either applied externally or externally and internally) could penetrate into the small gap and prevent corrosion.

Cathodic Protection: An Integral Part of Tank Maintenance

Product Number: 41206-283-SG

Author: Rog

Publication Date: 2006

$20.00

Barrier and inhibitor coatings are the primary defense against steel loss in water storage tanks. However, as a coating begins to deteriorate, action is necessary to prevent steel loss in the exposed areas of the substrate. Cathodic protection systems are an economical way to address preventing metal loss on the submerged surface areas of a water storage tank and have been proven to extend the useful life of coatings for immersion service.

CFRP Reinforcement Anode For Cathodic Protection Of Steel Rebar

Product Number: 51322-17877-SG

Publication Date: 2022

Only a few researchers have studied the effect of carbon fiber repair on corrosion processes. The main protective effect is the "protective barrier" which is sometimes called passive protection against corrosion, comparable to some techniques such as anticorrosion coatings of concrete structures. Indeed, CFRP materials, applied as external reinforcing material on reinforced concrete structures form a protective barrier against the penetration of moisture and pollutants such as chlorides or carbon dioxide.^1.2.3.4.5 Apart from this impermeable barrier action, it has been found in these studies that the confinement of CFRP concrete has a positive influence on the onset of corrosion and on its velocity. Very little research has investigated the coupling between mechanical reinforcement and impressed current system.^6,7,8

Coating Conductance Characterization Using Trenchless Crossing Data

Product Number: 51324-21037-SG

Author: Daniel Fingas

Publication Date: 2024

$40.00

Coating resistance or conductance values are critical input parameters for the accurate modelling and design of AC mitigation and cathodic protection (CP) systems for pipelines. However, there are relatively few sources for real-world coating resistance values in the literature. To attempt to fill this gap, data from coating quality tests performed on thousands of trenchless pipeline installations was used to characterize the coating resistance of new, primarily fusion bonded epoxy (FBE)-coated pipelines. The tests assess damage incurred as part of the trenchless installations and cover the full range from pristine coating to significant scratches with bare metal. This allows the dataset to provide insight into both a baseline for open-trench coating quality and a range of practical coating qualities for trenchless installations. It was found that specific coating resistance values varied from less than 100 O·m2 to >1 MO·m2 but that there was no specific threshold that could be associated with pristine FBE coating. However, the data clearly validated the ‘300 mV shift’ design guideline for CP systems, which also demonstrates the link between CP current requirement and coating quality. Considering this, the implication of requiring a certain current density irrespective of coating quality is illustrated.

Combining RMU, Annual Survey, and Groundbed System Design Data to Predict Capital Replacement Needs

We present a procedure to estimate the remaining service life of an impressed current groundbed using data analytics techniques to combine the various manually and remotely collected measurements, and rectifier groundbed metadata. Multiple data sources, including commissioning data, annual survey data, remote monitoring data were combined to create a consolidated dataset spanning over ten years for each impressed current cathodic protection (ICCP) rectifier groundbed. Using advanced analytics algorithms applied to ICCP rectifier groundbed sites, weighting factors have been calculated to determine the influence of each dataset on the estimated groundbed remaining service life. This work builds on previous presentations at AMPP Corrosion 2021 and 2022, where seasonality and historic trends in rectifier resistance measurements were modelled. By including additional datasets describing the location at the time of installation and the historic survey measurements, a more robust prediction can be made.

Comments On Standards Development For Selection And Specification Of Subsea Materials

Product Number: 51322-17491-SG

Author: Russell D. Kane

Publication Date: 2022

$20.00

In the oil and gas industry, the major standard for material selection today is ANSI¹/NACE² MR0175/ISO 15156 Parts 1-3. [1] While this standard deals extensively with environment cracking and its prevention for materials under exposure to production environments containing H₂S, CO2, chlorides, and sulfur, it does not include any guidance or material requirements for resistance to environmental cracking (such as hydrogen stress cracking – HSC, or otherwise) under variable subsea conditions that involve exposure to seawater with varying levels of cathodic protection (CP). ISO 21457 [2] provides further guidance for materials selection and corrosion control for oil and gas production systems but does not provide adequate coverage of the issue of environmental cracking in subsea applications with CP.

Comparative Study of the Effect of Sulfate-Reducing Bacteria on Cathodic Protection under Simulated Blisters

Product Number: 51324-21195-SG

This work presents a comparison of the effect generated by a mixed culture of sulfate-reducing bacteria (SRB) isolated from a natural estuary in western Venezuela, on the cathodic protection (CP) of carbon steel under simulated blisters. The laboratory study was carried out simultaneously measuring attack morphology, polarized potential, pH, and sessile growth, inside a simulated blister in a special cell arrangement, using two types of coatings: one 100% solids epoxy, and the other one, a tape type, which consists of the combination of a geo mesh-polypropylene textile and tarred rubber. A potential of -3.2 V vs. Copper Sulfate Electrode (CSE) was applied, which allowed to reach polarized potentials more negative than -950 mV Vs. CSE without the presence of coatings. Various conditions were considered for the study: A) sterile medium, B) sterile medium inoculated with SRB only outside the blister, and C) sterile medium inoculated outside and inside the blister. The correlation of the results for each case allowed the establishment of different comparative tables that could help to improve corrosion management methods of buried or submerged pipelines in presence of SRB. In all cases, a decrease in CP efficiency under the blister was demonstrated.
