Corrosion in Oil Platforms COMSOL Blog. 2015-10-7 In this case, the steel structure is electrically connected to a less noble metal, such as aluminum, that acts as an anode. The metal is sacrificed by slowly corroding as the steel structure acts as a cathode and is protected from corrosion. The Boundary Element Method Simplifies Corrosion Simulation corrosion in oil platforms comsol blog This blog post discusses an example where the BEM demonstrates its efficiency. Studying Corrosion in a Complex Structure. We wrote about the importance of corrosion management in oil platforms in a previous blog post. Such structures usually stand on a seabed with a jacket structure or float above the oil field as a floating production unit. Related searches corrosion in oil platforms comsol blog

How to Simulate Impressed Current corrosion in oil platforms comsol blog - COMSOL Multiphysics Modeling corrosion can be a truly challenging project if you want to capture all of the details of the physics and electrochemistry in the context of a geometrically large structure. Luckily, when modeling cathodic protection on larger scales, such as ship hulls, pipelines, or oil platforms, you can make some assumptions and valid simplifications. Highly Rated Corrosion Prediction Software and Corrosion corrosion in oil platforms comsol blog Oil and Gas Industry. CO2Compass: Modeling and Prediction of Corrosion by Carbon Dioxide (CO2), Hydrogen Sulfide (H2S), Acetic Acid (HAc), Elemental Sulfur (S), and Mercury (Hg) in Oil and Gas Pipelines and Production Tubing.
Corrosion is a widespread concern costing the US billions of dollars annually. For the Navy, specifically, it is the number one maintenance problem. Therefore, at the Naval Research Laboratory (NRL), researchers are developing a method based on multiphysics simulation that will aid material designers in producing corrosion-resistant materials. corrosion in oil platforms comsol blog Cost of Corrosion | Oil and Gas | Part 2 Australasian corrosion in oil platforms comsol blog Corrosion is an issue which is encountered in many stages of the oil and gas industries, including oil and gas pipelines, refineries, and petrochemical plants. Corrosion in oil and gas industry is usually caused by water, carbon dioxide (CO 2 ) and hydrogen sulphide (H 2 S). Anode Film Resistance Effect on Cathodic Corrosion corrosion in oil platforms comsol blog - COMSOL Anode Film Resistance Effect on Cathodic Corrosion Protection Application ID: 21101 This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products.
Use this model or demo application file (and its accompanying instructions) as a starting point for your own simulation work. THE MULTIPHYSICS SIMULATION MAGAZINE Global Solutions, modeling corrosion protection of an offshore oil platform, and improving safety on offshore oil platforms, just to name a few examples. This issue also highlights a model developed for the precise and long-term prediction of geothermal energy productiona groundbreaking approach with respect to comprehensiveness and ease of use. Multiphysics Modeling of Stress Corrosion in Underground corrosion in oil platforms comsol blog Modeling stress corrosion involves coupling mechanical and electrochemical interactions, which can be a challenge. Get a detailed overview of the equations involved and an analysis of the simulation results.
A corroded oil platform is a dangerous platform and it can cost you a lot in both lives and money. To avoid such a dark fate, you need to safeguard the steel structure from corrosion via a protection system, such as the cathodic protection process shown here. Corrosion Protection for Oil Platforms Electrodeposition Module Updates - COMSOL 5.3 Release Highlights A ship is anchored close to an oil platform. The ship hull is subjected to the electric field from the cathodic corrosion system. The figure here shows a ship where parts are of the hull are bare steel, where the hull may work as a bipolar electrode. Here, the stem works as an anode while the stern works as a cathode. Corrosion Protection of an Oil Platform Using corrosion in oil platforms comsol blog - comsol.pt Use this model or demo application file (and its accompanying instructions) as a starting point for your own simulation work.
This protection can be achieved by an impressed external current or by using sacrificial anodes. The use of sacrificial anodes is often preferred due to its simplicity. This example models the primary current distribution of a corrosion protection system of an oil platform using sacrificial aluminium anodes.
