Summary of Expertise:

Biodegradation mainly refers to enhanced degradation and deterioration of non-metallic materials such as concrete and polymers to distinguish it from microbial corrosion of metals. Under certain circumstances, there are groups of micro-organisms that are capable of attacking these materials and deteriorate them. Treating such cases needs a deep knowledge of corrosion (deterioration), materials science and microbiology. He has been dealing with this type of corrosion during his professional activities.



microbiologically-induced corrosion

Biological corrosion or microbiologically influenced corrosion (MIC) or microbial corrosion refers to a type of corrosion which is mainly electrochemical and is affected by certain micro-organisms, such as but not limited to, bacteria.

Not all bacteria increase the rate of corrosion and not all one hears about MIC is true. It takes a serious analysis of the corrosion case before calling it microbial corrosion. This is the main area of his expertise. He is the author of some books on this matter.

There are mainly three ways to mitigate microbial corrosion: physical (such using PIGs), chemical (such using biocides) and biological.


biological corrosion

Buoys are basically exposed to marine corrosion conditions and very vulnerable to microbial corrosion, among other kinds of corrosion. Most of the time, a good coating combined with a sacrificial anode approach can protect these structures for a long time. He has been involved in designing a cathodic protection system for some buoys himself.


Chemical plants are vulnerable to a wide range of corrosion processes. Therefore, one must be aware of the severity of corrosion in these plants and the ways to mitigate. Each plant has its own history and background of corrosion that must be noted when defining the corrosion problem(s) and related mitigation methods. He has been dealing with corrosion problems in this industry for some years.

chemical plant

The main types of corrosion that are expected in chemical plants are microbial corrosion, high temperature corrosion, pitting, crevice corrosion, stress corrosion cracking, coating failure and so on. It is indeed a very important task to define the corrosion kind and the part of the plant in which corrosion is happening correctly so that a suitable corrosion management plan can be defined.

chemical plant corrosion

Corrosion management is not only a technical issue. In fact, more than being technical, it is a "managerial" and "cultural' issue that calls for well-planned management of corroisonmitigation and prevention. In a chemical plant, there are various types of corrosion that have to be treated. A managerial approach, called "Corrosion Knowledge Management", invented and developed by myself, can help form a managerial approach to solve such problems.

chemical plant management

A very important step in dealing with corrosion is how to prevent it. In this respect, "corrosion prevetion" differs from "corrosion mitigation" as the former requires planning well ahead whereas teh latter deals with corroson when it has become a problem. Therfore, to prevent corroison one must not only look at the technicality of the issue but also the managerial-cultural elements attached to it. Corrosion knowledge management, invented and developed by myself, is a way that can be helpful for designing managerial approaches in addition to technical measures known as "corrosion management".

corrosion prevention

Use of corrosion resistant materials (including metals) is one way to both prevent and mitigate corrosion. For example, under certain circumstances, the use of grade 304 of stainless steels is not recommended. Therefore, based on the working conditions of each system, a wise material selection must be done. In doing so, not only technical compatibility but also economy of the choice must be highly regarded.

Desalination Units are very crucial in the sense of their duties ("creating" drinking water) and the types of problems they can have. A range of corrosion problems from microbial corrosion to stress corrosion cracking and galvanic corrosion can be expected in these Units. For each type, a certain corrosion management approach must be designed and applied. He has been in a major project regarding corrosion of desalination units for water industry.

desalination corrosion

Seawater is a biochemical "soup" that allows for both microbial and non-microbial types of corrosion to happen. The types of corrosion that can be expected in this environment are, but not limited to, microbial corrosion, chloride enhanced stress corrosion cracking, splash zone corrosion, chloride enhanced pitting corrosion, and so on. All of these types of corrosion need to be treated with a certain corrosion management approach to minimise the impact of corrosion. He is currently involved in many projects with the same topic.

marine corrosion

Due to the geometry of pipelines and their functions, they are vulnerable to a range of external and internal corrosion problems. A few of expecting corrosion problems in pipelines are, but not limited to, microbial corrosion, electrochemical corrosion, coating disbondment, lining problems etc.

pipeline corrosion


stainless steel pipe

There are a range of corrosion problems in power generating units. These problems range from, but not limited to, high temperature corrosion, microbial corrosion, chemical corrosion, stress corrosion cracking corrosion, cavitation and many more. These corrosion problems do need to be addressed through a corrosion management approach aiming at both prevention and mitigation of corrosion. he has a very good experience about the corrosion problems in power plants.

As water becomes motionless in storage tanks, it may create an excellent environment for microbial corrosion to happen. Other types of corrosion such as stress corrosion cracking can also be expected. If the tank is used for the storage of materials other then water, the types of corrosion to be expected can become even worse. Based on each single case, the corrosion scenarios must be carefully scrutinised and implemented.

storage tank corrosion

The combination of a corrosive environment with tensile stresses and a vulnerable material can create a type of corrosion known as "stress corrosion cracking" or SCC. This type of corrosion can be expected in a wide range of environments and applications ranging from marine industry to pipeline industry and aviation industry.

stress corrosion

Waste water is like seawater in the sense that a wide range of corrosion reactions can be expected in these environments. A well known type of corrosion observed in these environments is the microbial degradation of sewage systems. Treatment of corrosion in wastewater systems is a very delicate procedure that needs full attention and hands-on expertise especially when it comes to biodegradation processes.

wastewater treatment corrosion

By welding, specially thermal welding, the microstructure of the material is changed vastly. If post-weld treatment is not applied, welds and especially heat affected zone (HAZ) will become the main weak points when it comes to corrosion, and especially microbial corrosion. He has been technically involved with this matter for some years.
