Zinc Anode Calculation for Ships: A Guide to Effective Corrosion Prevention

Introduction: Corrosion is a major problem for ships, and it can lead to costly repairs and maintenance. Zinc anodes are an effective way to prevent corrosion on ships, but it’s important to calculate the right number of anodes needed to protect the ship. In this blog post, we’ll discuss zinc anode calculation for ships, how…

The Importance of Cathodic Protection for Ship Hulls with Sacrificial Anodes

Introduction: Cathodic protection is a widely used corrosion prevention technique for metal structures, including ships and boats. The hull of a ship is especially vulnerable to corrosion due to the harsh marine environment. In this blog post, we will discuss the importance of cathodic protection for ship hulls, and how sacrificial anodes can help to…

Cathodic Protection: The Ultimate Guide to Corrosion Prevention for Metal Surfaces

Corrosion is a natural process that can cause significant damage to metal surfaces over time. From pipelines and tanks to ships and infrastructure, the effects of corrosion can be costly and even dangerous. Fortunately, there is a solution: cathodic protection. This innovative technique uses sacrificial anodes or external power sources to protect metal surfaces from…

Hybrid Corrosion Protection Systems for Prestressed Concrete Bridges

Hybrid Corrosion Protection

Many reinforced concrete structures like prestressed concrete bridges can suffer from corrosion damage. Causes include salt ingress from the application of de-icing salts during winter maintenance, exposure to marine environments and carbonation of the concrete. TRADITIONAL CORROSION PREVENTION METHODS FOR CONCRETE Corrosion is an electrochemical process and the use of electrochemical technology treatments is a…

Steel pontoon in quay Initially, it is possible to stop or delay the progress of corrosion on both new and older protective objects. Steel pontoons in berths are effectively protected by cathodic corrosion protection. On the west coast and in the Baltic, sacrificial anodes are usually used. North of Gävle, corrosion protection with applied current…

Cathodic Protection below the waterline (ship hulls)

Cathodic protection

In this post we take a “deep dive” into cathodic protection below the waterline. Primarily regarding the hull of ships and vessels. It is almost impossible to cathodically protect a hull that is not coated, due to protection current requirements and current distribution. In addition to this, there must be an electrically insulating layer between…

Sacrificial anodes – understanding the importance of anodes on boats

Sacrificial anodes

Revised by Hans Karlsson, Corrosion engineer with 30 years of experience within the cathodic protection industry . Whenever you have two distinct metals that are physically or electrically associated and submerged in seawater, they turn into a battery. A small amount of current streams between the two metals. The electrons that make up that current…

Pipeline Corrosion Prevention Methods for Oil and Natural Gas Pipes

h2-blog-img-01

Due to several pipeline explosions over the past few years, pipeline corrosion prevention for oil and gas pipelines has become a “hot” topic within the energy sector. Both for the devastating damage that it causes but also for the lives it takes, in our opinion, it’s a subject worth discussing. Here are some of the…
