Inventing new ways to reverse the corrosion cell

As all of us know, cathodic protection – CP - is one of the oldest and most efficient anti-corrosion methods; 200 years ago, our colleague Humphrey Davy recommended the technique to control corrosion on British naval ships. From an engineering perspective, it is an essential tool for protecting structures everywhere. Some of the more demanding sectors of CP include O&G, water & wastewater, industrial plants, ships, and nearshore structures in general. By application, pipelines are in the first place, followed by storage tanks, processing plants, and transmission towers. The cost savings associated with using the CP are not easy to estimate. Besides, global calculations showed that in 2018 the CP market was USD $4.265 million. According to an estimated CAGR of 5%, it is expected that such an amount could be about USD $7.064 million in 2027. Consequently, there is a strong reason for a growing interest in the subject and searching for better answers concerning CP use. Evidence of this trend is the presence of asked patents currently submitted. Today, We have three examples of patents filed with the US Patent Office. The first one is about applying energy transition to CP using solar energy to protect concrete rebar. One more example is related to the application of CP in a vital situation related to the energy transition. This is the case of CP for offshore wind turbine poles. In the end, a third example refers to an exciting development about cleaning and CP of inner water pipe surfaces.

Title: Cathodic protection for offshore wind turbine steel support structures

Author(s): Birit Buhr Jensen

Applicant(s): Orsted Wind Power A/S

Priority date: 28.01.2020

Summary: In this case, the applicant's claims are concerned with a cylindrical support for offshore wind turbines. Inside the structure is located a control unit, and on the outside pole surfaces, galvanic anodes are placed. The control unit contains reference electrodes to estimate the polarization requirements of the structure. According to the variability of the required protection, the spatial distribution of the anodes can be calculated and the rate of electrons flowing towards the cathode controlled.

Title: Apparatus and Method for In-Situ Cathodic Protection of Piggable Water Pipelines

Author(s): Husain Makki Al-Mahrous

Applicant(s): Saudi Arabian Oil Company

Priority date: 28.04.2020

Summary: The declared invention refers to a pig device able to clean the inner surface of a pipeline. Such a device includes an anode of mixed metal oxide, platinized niobium, and titanium, encapsulated in a cured wax cementitious material containing mullite and corundum. Thus, the pig simultaneously acts as anode of a cell where the pipeline becomes cathodic thanks to the external electric current impressed.

Technology to help monitor and maintain solar farms

Airobotics, an Israeli manufacturer of autonomous drones and aeronautical data platforms, and Solar Drone, an Israeli company specializing in solar farm services, have signed a binding agreement under which this company will develop and supply an exclusive solar cleaning drone for the solar panel. Airobotics and Solar Drone aim to leverage their expertise in drones and solar energy systems to create and market a new drone-based cleaning solution, forecasting sales of $10 million in the first three years in Israel, Europe, India and the UAE.

The 3rd issue of Journal of Pipeline Science and Engineering

The Journal of Pipeline Science and Engineering aims to provide an essential medium for communication and dissemination of new ideas, original research, and technology innovation in the general area of energy pipelines transporting oil, natural gas and non-conventional fossil fuels (e.g., heavy oil, diluted bitumen, shale oil, shale gas and oil sands slurry), as well as hydrogen, carbon dioxide and biofuels. The 3rd issue of J. Pipeline Sci. Eng. is now online. All papers are accessible, and free to download. This is a special issue on Risk and Reliability Assessment of Pipelines. You will notice articles such as:

● An investigation of mitigating the safety and security risks allied with oil and gas pipeline projects

● Dynamic reliability model for subsea pipeline risk assessment due to third-party interference

● Research and application of natural gas pipeline assessment method in Location Class upgrading areas

Augmented reality –AR- is now one of the most disruptive technologies

Augmented reality AR made the buzz a few years ago, although AR was born as a key technology in this research, at the time the plan's allies felt it was not being used positively in construction, for one of the organization's automotive customers interested in minimizing shop floor errors and waste, the use was so successful that productivity increased by 20% and errors were nearly zero. Kit-AR is now installed in a different process on the buyer's assembly line to minimize critical errors and facilitate line balancing.
