An Evaluation of Micro biological corrosion in the maritime environment

Key Information

Supervisors: Dr Chris Wright and Dr Chedly Tizaoui

Expected Interview Date: March 2020

The environmental conditions in many locations on board maritime vessels or marine structures can favour the proliferation of microorganisms associated with microbiologically influenced corrosion (MIC). A wide range of different materials are used in the construction of maritime vessels, in both structural and support elements, and many of these material types have been shown to be susceptible to microbiologically influenced corrosion (MIC). The company are seeking a greater understanding of these corrosion issues as they present a significant problem with thier floating craft.

The main microbial families concerned with MIC are

  • Sulfate Reducing Bacteria SRB) – most common and best understood MIC Bacteria
  • Acid Producing Bacteria (APB)
  • Iron Oxidising Bacteria (IOB)
  • Slime Forming Bacteria (SFB)
  • Sulfur Oxidising Bacteria (SOB)
  • Nitrate Reducing Bacteria (NRB)

 

Why are SRBs a problem?

In engineering SRBs cause problems when sulphate containing water comes into contact with metal. A chemical reaction occurs which produces a layer of molecular hydrogen on the metal surface. The SRBs then oxidise this molecular hydrogen to create hydrogen sulphide which contributes to rapid corrosion.

 

Aim of Project:

To develop a better understanding of biocorrosion to ultimately aid in the design of better MIC prevention and mitigation strategies. This can be conducted for a variety of fabrication materials with exposure to MIC bacteria-containing media, including oil and gas pipelines, ballast water tanks, steel pilings in marine applications, and, more recently, offshore wind farms.
