Advanced Subsea Corrosion Protection via Modulated Impressed Current Cathodic Protection a Prototype Demonstration and Comparative Evaluation

Product Number: 51324-20812-SG

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.

Break Reduction/Life Extension for Municipal Water Pipelines

Product Number: 51324-20658-SG

Author: Erin Nelson; Ed Richey

Publication Date: 2024

A 2018 study by Utah State University indicated that the condition of North America’s water infrastructure is in a state of steady decline. That research determined that the water main break rate increased 27% for the 6-year period between 2012-2018, with over 80% of the cast iron pipelines currently in service being over 50 years old. Referenced statistics indicate there has been an average of 14 leaks per 100 miles of operating pipeline, and that each mile of pipeline serves approximately 300 consumers. Further increases in the water main leak rate represent a major disruption in reliable water supply to a large population. Excluding third-party damage, metal loss because of corrosion is the most common cause of premature failure and leakage of buried pipelines. Corrosion is a predictable process, whereas third-party damage is random in nature. Methodologies have been developed over the past few decades to identify anomalies and areas susceptible to active corrosion on underground pipelines. Using the data from these analytics, it is possible to implement local corrosion control to rapidly decrease the water main break rate. A methodology has been developed and applied to drive this process in a systematic approach. Break Reduction/Life Extension (BRLE) is a proactive engineering program developed to: · Reduce the number of future breaks on water system piping · Extend the operational life of existing water system piping Using a combination of factors, such as pipeline age, materials type and break history, with the data gathered in the field, it is possible to identify activities to initiate measures to reduce the water main break rate. This paper will present details on the BRLE methodology and provide data from case studies to demonstrate the effectiveness of this approach.

Cathodic Protection -Based Solutions For Corrosion Prevention Of “Green Aluminum” Alloys

Product Number: 51322-17823-SG

In the recent years, the reduction of the environmental footprint of industrial processes is gaining momentum, targeting the carbon neutrality. This also involves Aluminum industry, in which the use of secondary (e.g. recycled) alloys is a possible solution in order to decrease the greenhouse gases (GHG) emissions. Indeed, raw materials produced starting from secondary Aluminum show GHG emission values up to one order of magnitude lower with respect to their primary equivalents.

Corrosion Assessment to Extend Vessel Continuous Operation Subsequent to Depleted Anodes Indications

Product Number: 51323-18992-SG

Author: Muntathir M. Al-Jumaah, Usman Shahzad, Mamdouh H. Hadi

Publication Date: 2023

In gas-oil separation plants (GOSPs), multiphase crude is separated, degassed and then dehydrated before being shipped to stabilization plants for further processing. Typically, in ageing oil fields, the crude is accompanied by large volumes of formation water that is separated in GOSPs using three-phase production traps, which are large horizontal vessels, using a gravimetric separation process where water collects and settles at the vessel’s lower part.

Steel is a common material for the construction of large infrastructures. It is a main constituent used for building of, offshore drilling platforms, steel cast dock, pipeline in seabed, coastal bridges and ship hulls. Corrosion of offshore structures is a serious matter in terms of degradation and deterioration of these structures in a corrosive electrolyte such as seawater, which could lead to fatigue cracks, brittle failure and unstable failure.

HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.
