The Deputy Vice Chancellor of the Federal University of Petroleum and Resources, FUPRE, Engr. Akpofure Rim-Rukeh, has charged the Nigeria National Petroleum Corporation, NNPC and other oil and gas firms to be mindful of the impact of microbial corrosion on petroleum production facilities.Rim-Rukeh had also prevailed on the oil and gas firms to periodically ensure the integrity of their facilities, calling on them to support research initiatives of the Universities at all times.
Rim-Rukeh explained that Corrosion process where microorganisms are able to initiate, facilitate or accelerate the corrosion reaction without changing its electrochemical nature is called microbial corrosion and also known as biocorrosion or microbiologically influenced corrosion. Prof. Rum-Rukeh said, “The first step in investigating metal failure as a result of microbiologically influenced corrosion is to study the physico-chemical and biological characteristics of the environment of the metal failure.
“The presence of Leptothrix discophora increased the corrosion rate by about 123 percent and a pipeline of wall thickness 0.25 inch will corrode microbiologically after 12 years of installation at a rate of 2.08mpy.”
