MIC prevention in world's longest gas transport tunnel

In 2014, the English gas supplier National Grid issued a tender to replace the pipeline under the Humber River. 20% of the natural gas used in England is transported through this pipeline. The location of the pipeline is worrisome because it is close to the mouth of the river in the North Sea. Due to the tide with a height difference of 6 meters, a very strong current is created. As a result of this current the gas line gets more and more exposed. To solve this problem, a 5 km long tunnel with a diameter of 4 meters is constructed at a depth of 31 meters under the river. One of the requirements is that the tunnel has a lifespan of 120 years. The gas line is assumed to have a service life of 40 years.

You want to be sure if biodegradation of contaminants takes place in soil and groundwater?

At the Defence Island in the municipality of Woerden there is pollution in the deep groundwater, which was caused by military dry-cleaning activities in the past. It involves the volatile chlorinated hydrocarbons (VOCl’s), cis-dichloroethene and vinyl chloride. The municipality is developing a plan for the management of this deep contamination and would like to be certain whether biodegradation of the VOCI’s occurs and if so, at what speed this happens. Bioclear earth has been engaged to look into the matter.

Research into microbiologically influenced corrosion in drinking water pipelines

You probably never think about it when you turn on the tap for some water, to make coffee for example, what is needed to get that water to your residence. Vitens is a company that ensures that no less than 5.7 million people in the Netherlands are supplied with clean drinking water every day. Every year the company supplies more than 330 million m3 of water via a network of pipelines with an impressive length of 49,600 km. Try to imagine this for a moment, that is longer than the circumference of the earth! Maintaining such a network is quite a challenging job.

Are microorganisms responsible for corrosion in uncoated underground diesel storage tanks?

Over the past years tank inspectors observed an increase of corrosion in uncoated underground diesel storage tanks. This is alarming, because corrosion could possibly weaken the tanks, which could cause fuel to leak into the soil and induce environmental damage

Offshore wind turbines threatened by hungry bacteria?

In recent decades, approximately 80 offshore wind farms, accounting for 2850 wind turbines have been built as part of the transition from fossil fuels to renewable energy. Installing offshore wind turbines is a challenge in itself.

MIC research in offshore oil pipelines

TAQA is an international operating energy- and water company located in Abu Dhabi. TAQA is Arabic for energy. The company engages in generating energy, oil and gas production, water desalination, pipelines and gas storage. Safe and good functioning of pipelines is evidently very important to the company. 

How can we prevent well clogging of geothermal systems?

Good bacteria create tasty sausages

For decades the meat industry has been working with the same process of meat fermentation to preserve products like salami, saveloy and filet americain. Fermentation is one of the oldest methods to preserve food by using bacteria, fungi and yeasts. This preservation process is not always optimal, which in addition to a less tasty product can also lead to microbial risks.

Is recycling overflow dredging sludge safe?

Overflow dredging sludge is sludge that is removed from ditches and canals in the vicinity of a sewage overflow.  Often, this sludge is polluted because in case of heavy rainfall the sewage water and sludge will flow into the overflow simultaneously.

Fire extinguishing pipes

At the request of a client, we have conducted an investigation of a fire extinguishing system, which was installed in a waste processing plant. After several years, leakage occurred in the system regularly. The nature of the damage suggests that it could be caused by microbiologically influenced corrosion (MIC).
