How to detect microbial contamination of fuel?

 in the fuel tank, and corrosion are some of the most common fuel tank problems. If such issues are not dealt with in time, it can lead to a significant catastrophe. Microbial contamination or diesel bug can post a threat to the integrity of the fuel.

In this post, we will look into some early signs of microbial contamination of fuel. Knowing the symptoms will help you keep a check on the fuel and take timely action in case of any spoilage.  

#1 Water in the Oil Tank.

Most tank inspection services companies look for water in the oil to determine microbial contamination of the diesel. While water contamination in fuel tanks is usual, if the amount of water in the oil increases, it can lead to further damage. The water level in the oil tank also allows the inspectors to determine how significant the contamination is and how to resolve the problem.

Water can seep into the oil tank directly through a hole in the outer layer of the storage container or indirectly through the air. At the start of the water contamination, the water inside the tank is in the form of invisible molecules. However, once the amount of water in the air inside the oil tank reaches a saturation point, it emulsifies and forms water droplets. Water in the fuel can turn it cloudy, which is a sign of water contamination. If the water in the tank is not handled in time, small puddles of water will start forming at the bottom of the tank. Eventually, bacteria and bugs will start appearing, which will further degrade the quality of the fuel.

#2 Corrosion in Fuel Tank.

Corrosion or rust can form outside or even inside the fuel tank if it’s not maintained correctly. Corroded fuel tanks often indicate microbial contamination. When the bugs or microbes grow in numbers inside the container, they start to eat away the tank, causing tank erosion.

Corrosion of the tank should not be overlooked as it poses a threat to the environment. Oil leakage from eroded tanks is common that often leads to contamination of water bodies and wildlife. Moreover, cleaning up oil spills is very costly. Thus, it’s essential to perform timely oil tank testing to identify tanks corrosion early.  Besides this, tank operators should ensure their tanks are periodically inspected by professionals who have undergone tank inspection training.

#3 Bug in the Fuel.

Microbial growth in fuel tanks is often referred to as diesel bug. Bug in fuel can form due to water in the oil tank. The bug will start to multiply quickly if the level of water in the oil tank is more. Since fuel sludge form on the underside of the tank, it’s hard to detect from above. Only qualified tank inspecting professionals can identify the location of the sludge.

It’s worth noting that not all contamination is harmful. The professionals determine whether the contamination of fuel is negligible, moderate, or heavy. Once the level of contamination is identified, it’s easier to take care of it.

The Latest Advancements in NDT inspections and Analysis

The pandemic has disrupted the entire world economy. Many industries are going through transformational changes due to the effects of the COVID-19 outbreak. Businesses that are able to adapt to new situations can enhance their chances of survival. When it comes to the storage industry, the norms and standards keep evolving. Thus, API inspection companies should constantly strive to adopt new advancements and testing techniques. Doing so will not only help them improve their services and stay compliant, but it will also save them time and cost. By employing cutting-edge technologies, they can manage overheads and efficiently address safety issues.

Tank storage inspection companies widely use Non-destructive techniques. NDT inspections offer a wide range of advantages. They provide accurate and reliable results and don’t hinder the functioning of the machinery.

In this blog, we have highlighted some advancement in non-destructive testing.

Phased Array Ultra-Sonic Testing Techniques

One of the recent advancements in the NDT method is Phased Array Ultrasonic Testing or PAUT. Many tank inspection companies have moved on PAUT from the usual ultrasonic testing methods. In ultrasonic testing, pipes are inspected to analyze weld joints, tanks, and pipe lays. Inspection of storage tanks with complex geometries is not possible with the simple ultrasonic method.

This is where the phased array ultrasonic testing comes in handy. Through PAUT, the inspector can analyze the complex assembly of pipes through various angles and positions without moving the device. Phased array ultrasonic testing technology has not only simplified the testing process it has made it more reliable. The technician can probe pipes of the entire storage system in comparatively less time.

Non-Destructive Examination 4.0

While NDT offers more advantages, it has its fair share of downfalls. One of the most significant shortcomings of non-destructive testing is it lacks effective communication. The new NDE 4.0 aims to rectify this shortcoming and enhance internal communication. Digital tools have further helped API inspection services providing companies to speed up the inspection process and decrease the time required to analyze the equipment. Now, the technicians can take pictures of the tanks and equipment and send them to managers for further evaluation. If there is an issue with the installment of the tanks, the manager can send their feedback and have it rectified. The same can be done to check whether a storage facility is compliant.

Data Formats for NDE 4.0

For a very long time, the information for NDT was stored in a proprietary format. The proprietary system leaves little room for open communication between various stakeholders. When it comes to ensuring the correct implementation of tanks and their components, documentation is essential.

Recently, experts have suggested a more feasible model for documenting storage tank requirements. Digital Imaging in Non-Destructive Evaluation or DICONDE has been proposed to support a unified portal for data exchange.

AI and Robotics

Advancements in artificial intelligence have opened new ways for effective tank inspection and evaluation. NDT inspection companies are making use of drones, robotics, and other artificial intelligence technology to reach unreachable regions of the tank for a complete and accurate result.…
