Oil and Gas Industry Partners Join Together to Prevent Pipeline Corrosion

Pipeline corrosion is a huge headache. The last thing project managers want to hear is that microbes in the soil are chomping away at pipeline projects that they have spent years on.
 
The European-based DNV GL, a global maritime and oil and gas safety consulting and accreditation organization, feels that the oil and gas industry needs to take a stand. Corrosion is a serious threat.
 
DNV GL is calling for industry partners to join together to form a joint industry project (JIP) against microbiologically influenced corrosion.
 
The issues with microbiologically influenced corrosion
 
Microbiologically influenced corrosion can occur in unpredictable areas of a pipeline even if it is well protected. The JIP intends to develop practices for the detection and removal of microbiologically influenced corrosion.
 
The pesky microorganisms involved in pipeline corrosion are quite complicated. Many factors affect them such as soil type, heat and moisture. However they are so good at what they do that they account for 20 percent of the annual corrosion costs in the US.
 
The microorganisms work by basically housing themselves and their families on pipelines. These biofilms (microorganism ecosystems) alter the electrochemical conditions on the metal surface. This then allows corrosion to occur.
 
Solutions
 
As these microorganisms are so difficult to get rid off, the best bet is to protect pipelines better. This will involve the JIP looking into more effective coating and cathodic protection for pipelines.
 
The JIP also hopes to help pipeline operators test sites for levels of microorganisms and will make a tool that ranks the risk of microbiologically influenced corrosion along areas of a pipeline.
 
Decreasing pipeline corrosion will help to increase the safety of oil and gas pipelines by decreasing the chance of leaks. It will also drastically increase the lifetime of pipelines drastically reducing costs needed to repair or replace them.
 
If the JIP is successful it could mean a huge win against the fight against corrosion for the oil and gas industry.
