The IVR Association has published an information document explaining the hidden risks of biological corrosion and providing additional information on how to avoid bacteria that damages ship bilges. The technical leaflet Biological Corrosion focuses on a number of cases where the issue of leaking engine rooms seems to be more and more common as a result of this type of corrosion.
In recent years, an increasing number of cases of leaking engine rooms, caused by very local perforations of the ship’s plating have been noted. This happened despite the recent class renewal in which bottom inspection and thickness measurements showed that the plating was sound. In these cases, investigation reveals that the water ingress is by very local corrosion perforations. Continue reading “The hidden risks of destructive biological corrosion”
