Offshore wind farm owner, engineering firm
Currently, in the planning of a new offshore wind farm in the North Sea, microbiologically influenced corrosion (MIC) is also taken into account as a possible corrosion mechanism in the context of a corrosion risk assessment for the foundation construction.
A complete microbial analysis was performed on cores to determine whether corrosion-relevant micro-organisms exist in the sediment on site. Endures uses a combination of two methods: the MPN method, which is based on the cultivation of bacteria, and q-PCR, a molecular technique that determines the composition of DNA.
Corrosion-related microorganisms were indeed found in samples from various locations in the planned offshore wind farm. Microbial activity was also determined at different depths in the sediment. On the basis of this data, an assessment was made of the possible corrosion risk for the metal structures to be placed at that location at a later date and advice was given on corrosion protection measures. In addition to microbiological research, Endures can also help you choose a suitable system for corrosion monitoring.
