This study introduces a modulated Impressed Current Cathodic Protection (ICCP) system, specifically designed for Oil & Gas subsea production structures. Unlike traditional Sacrificial Anode Cathodic Protection (SACP) systems, which provide a constant output, the prototype operates on a closed-loop feedback system to dynamically control cathodic potentials within a specified voltage range. This allows for adjustments to varying environmental conditions, such as seawater temperature and microbial activity. The paper outlines the design, development, and testing of this innovative ICCP system and offers a comparative evaluation with existing SACP methods. In doing so, it addresses some of the limitations of current SACP systems, including issues like hydrogen embrittlement and premature anode depletion. The goal is to demonstrate the enhanced effectiveness and sustainability of the proposed ICCP system in subsea corrosion protection. Future work aims to integrate a patented predictive modeling feedback mechanism to further optimize the system's adaptability.

The protection against corrosion of the pipelines of the Crossbridge refinery in the West of Denmark is described in this paper. During years the pipelines in this refinery suffered significant external corrosion despite a Cathodic Protection, CP, system was in place to protect two different environments, onshore and offshore, from one sole location. Of all the pipelines being under cathodic protection, one suffered from severe corrosion at specific locations. Initially, the CP system was intensively evaluated with the outcome that a replacement of the pipeline was the best option. However, only after detail investigation of the process, the installation of online ER-probes to monitor current, potential and corrosion rates and the evaluation of the foreign pipelines the possible issues were identified. Environmental conditions, soil and sea water resistivity, flow temperatures and foreign district heating pipeline all affected the corrosion of the largest of the export pipeline, a 24” pipeline. Conclusions of the investigation, updated design and mitigation measures will be described in this paper.

Internal ICCP of Offshore Wind Monopile Foundations

Product Number: 51323-19376-SG

Author: Christophe Baete, Aldrich Tyto

Publication Date: 2023

Despite rapid development of electricity generation from wind compared to other renewable power sources in recent years, much greater efforts are still required to achieve the current level of sustained capacity growth to get on track with the Net Zero Emissions (NZE) by 2050 Scenario. One of the main challenges remains around the sustainability and cost reduction efforts for the offshore wind sector, especially related to operation and maintenance (O&M) costs. Monopiles, the most common foundation type in offshore wind farms, just like any other submerged metal structures are susceptible to corrosion, the maintenance of which could be very costly.

Corrosion prevention of the inside of a monopile structure has been challenging until today.

NACE SP0572-2024, Design, Installation, Operation, and Maintenance of Impressed Current Deep Anode Systems

Product Number: NACE SP0572-2024

Publication Date: 2024

$109.00

The purpose of this AMPP standard practice is to present procedures and practices for the design, installation, operation, and maintenance of deep anode systems used for the control of external corrosion of underground or submerged metallic structures by impressed current cathodic protection (ICCP). It is intended to be used in conjunction with NACE SP0169 and SP0177. This standard is intended to be used by corrosion engineers, corrosion consultants, representatives from manufacturers, and others concerned with corrosion control of underground structures.

The performance of titanium mixed metal oxide (MMO-Ti) anodes — provided by five global vendors — targeted for coke breeze backfilled soil impressed current cathodic protection (ICCP) applications, was investigated in this study. The time to failure of the MMO anodes was measured in accordance with NACE TM0-108. Accelerated lifetime testing was performed on MMO anodes to measure sample durability and to adequately meet the current density design requirement (0.06A/cm2). The anodes were immersed in 1M sulfuric acid under varying current densities (1A/cm2, 1.4A/cm2 and 2A/cm2) under controlled temperature, until the samples lost their electro-catalytic properties. The results measured at 1A/cm2 illustrated that time to failure of the tested anodes ranged from 10 days to more than 90 days. While conducting the same test at 1.4A/cm2, time to failure of MMO anodes was reduced to a range of 13 days to a little over 30 days yielding results of anode ranking consistent with those measured at 1A/cm2. Therefore, for the sake of time, the optimum applied accelerated current density was recommended to be 1.4 A/cm2 for Ru/Ta MMO anodes, to push them to their limits at a faster rate in a shorter time.
