Technical day - electrochemical impedance spectroscopy

Yesterday, a technical day was held at the company's premises, attended by our colleagues Ivana Šoić and Margareta Postonjski from RecorrTech, as well as Tea Antolović, head of the laboratory for anticorrosion protection at MONTER-SM in Zagreb.

 

The topic of discussion was electrochemical impedance spectroscopy (EIS), a technique that enables the assessment of barrier performance and the prediction of the durability of protective coatings. Key aspects of EIS were presented, such as precise low-frequency impedance measurements (log Z at 0.1 Hz), highlighting its importance in planning maintenance and coating replacement before severe damage occurs.

 

The participants shared several case studies, including the application of EIS on offshore platforms and laboratory samples, and emphasized the significance of standards EN ISO 16773 and ASTM D8370-22, which provide a normative framework for the EIS technique. The water uptake module (WU%) was also explained, showing how it complements impedance measurements to offer a clearer picture of coating degradation.

 

The meeting also explored the development of an EIS service tailored for offshore platforms, aimed at helping owners make informed decisions about re-coating, particularly in scenarios where extending the lifespan of offshore structures is critical for cost optimization and operational safety.

 

This meeting was a valuable step toward broader implementation of advanced methods for assessing and maintaining anticorrosion systems, providing guidelines for further development and application of these techniques.

AUTOMA Smart Grid Days 2024

Smart Grid Days is the AUTOMA event that since 2014 has become part of the agendas of industry players around the world. The event is set up as a multi-voice and multi-handed account on the news concerning the world of remote monitoring and control of pressures and cathodic protection.

Together with the major institutional realities of the sector, the international regulatory evolution and 4.0 technologies are explored: Data Analytics, IoT, Security and Smart Grids. All the ingredients for an event rich and dense with content, designed with insiders for insiders.

The goal of Smart Grid Days is to find new stimuli and new solutions to run into the future and seize new opportunities.
The event is held every year in the magnificent scenery of the Conero Riviera (Italy).

Case study "Systematic and repetitive failures in cathodic protection designs: lessons learned from power plants’ piping systems" with the collaboration of Tea Antolović was presented by Krešimir Kekez during SmartGridDays2024 of Automa in Ancona.

EUROCORR 2024

EUROCORR 2024 took place in Paris, France, from September 1^st to 5^th, 2024. The venue was the Palais des Congrès de Paris, ideally located within walking distance from the Avenue des Champs-Élysées and easily accessible by public transport. EUROCORR2024 has covered all aspects of corrosion science, technology, and engineering, with emphasis on a main theme:

"A step forward in societal awareness of material degradation issues"

Mr. Stjepan Pavliša and Mr. Krešimir Kekez have held presentations during the EUROCORR congress based on the following themes: "Electrical safety measures in cathodic protection systems" te "Systematic and repetitive failures in cathodic protection designs - lessons learned from power plants’ piping systems".

CETRA 2024

"Cathodic protection of pile caps on Pelješac bridge: in-depth analysis of the system" is the paper that was presented at CETRA 2024 (8th International Conference on Road and Rail Infrastructure). It was a great experience discussing our findings on the effectiveness of cathodic protection systems.

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!

CATHODIC PROTECTION OF WATER HEATER VESSELS FOR A HOTEL ON THE ADRIATIC COAST

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.

The interesting program of the conference included 10 current thematic units, related to the most current topics in the field of gas economy and energy.

The conference discussed the contribution of natural gas and gases from renewable sources in achieving a sustainable transport system. Numerous domestic and foreign experts presented papers on the issue of transportation, distribution, storage and consumption of natural gas with regard to ensuring an efficient, reliable and low-carbon gas system. Several interesting papers presented legal risk control instruments during the global energy crisis and the upcoming legislative regulation of hydrogen in Croatian legislation, as well as comparative solutions from other member states.

There was also a speech on the protection of end consumers in gas distribution systems and the influence of fuel value. Numerous exhibitors from the country and abroad presented advanced technical solutions for gas economy and energy at the exhibition of gas equipment and technology, which was held in parallel with the conference.

SAFETY MEASURES FOR USE OF ELECTROTECHNICAL INSTALLATIONS AND EQUIPMENT ON GAS FACILITIES

As part of the newest edition of quarterly journal “PLIN” released on December 2022. an article has been published about “safety measures for use of electrotechnical installations and equipment on gas facilities”.
The article was presented by author Stjepan Pavliša during the last year’s international scientific & expert meeting of gas professionals held during May 11-13, 2022 in Opatija.

Short abstract: 

All gas facilities are largely dependent on operation of integrated electrotechnical installations and equipment inside the gas facility system.

Due to safety requirements on gas facilities, electricity usage requirements are much more complex than the requirements for conventional electrical installations in general use.

Which is why this article is dedicated to the practical applications of compliant and non-compliant electrical installations and equipment regulations and standards applied to this area of expertise.

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.
