Corrosion Awareness Day 2024

Today, we recognize April 24th as Corrosion Awareness Day, designated by the World Corrosion Organization (WCO). It's a day to shine a light on the silent yet significant impact of corrosion on our world.

Corrosion silently erodes infrastructure, from bridges to pipelines, costing billions annually and endangering lives. It affects industries, from aerospace to maritime, compromising safety and efficiency. Yet, awareness of corrosion effect severity remains low.

This day serves as a reminder to individuals, industries, and governments to prioritize corrosion prevention and mitigation efforts. It's a call to action to invest in research, education, and innovative technologies to combat corrosion's destructive effects.

Let's join hands to protect our infrastructure, environment, and economy from the corrosive forces that threaten them. Together, we can build a safer, more resilient future.

Getting ready for another offshore journey to keep subsea pipelines in check!


Four additional water heaters have been supplied to the fleet of vessels under the permanent protection of the ICCP system. After 16 years of service, significant corrosion led to hull perforations. Moving forward, corrosion loss will be permanently arrested for the remainder of the vessels' operational life, without the need for equipment replacement.

This process is automatically controlled using Zn pseudo electrodes, with current supplied by a Ti+IrO2 anode. Furthermore, two weight loss coupons (CP and non-CP) are installed for enhanced evaluation later on.

CPDL-1 data logger technology overview

PA-EL’s CPDL-1 data logger provides simple and reliable way to store measured data on the state of cathodic protection of metal structures. In use, the CPDL-1 data logger behaves like a “black box” on cathodically protected structures and stores cathodic protection data within its memory until it is recalibrated.

Storage of cathodic protection measurement data on the CPDL-1 is performed in the defined time intervals during which the measurement data from the reference electrode is written to the data logger’s memory. The frequency of data logging on the CPDL-1 can be set in the range of 5 seconds up to a week per record, while the built-in non-rechargeable battery inside the data logger allows device autonomy of at least one year at a recording rate of 1 log/hour.

The collected data from CPDL-1 can be transferred to the computer using the software tool CPDL-1 user, for which it is necessary to connect the data logger to the computer with a USB cable type “USB-A <-> USB mini”. After downloading, data / measurements taken from the data logger are stored in .csv format and after transferring to a computer, it can easily be opened via standard spreadsheet applications such as MS Excel, Libre / Open Office Calc and similar programs, where the data can additionally be processed as required.
