OPIN is conducting a survey on current practices for corrosion protection of offshore reinforced concrete structures.

Steamship Mutual published a Risk Alert focusing on the issues around the corrosion in the exhaust gas scrubber system.

The Marine Safety Forum has published a Safety Alert relating to the discovery of a leak in a tank caused by corrosion. The incident highlights issues associated with the disposal of caustic chemicals. 

In its latest Safety Flashes for May, IMCA analyzed a case where a flood light had not been identified as a potential dropped object by the crew, causing hidden corrosion.

Following the latest version of IMCA's Safety Flashes, it is described a case where during replacement of a lifeboat embarkation ladder, was identified a total failure of the natural fibre rope at the securing thimble.

It is known that without protection, a submerged steel surface will gradually corrode, that is why steel quay walls are generally fitted with sacrificial anodes. Although, there is an alternative protection method: using anodes that are charged with ‘impressed current’.

Recently, ClassNK has received several reports for incidents that sea water leakage was detected from distance piece attached to hull on SOx scrubber discharge water line. The design and possible problems are similar for all vessel with scrubber installations.

The IVR Association issued an informing paper explaining the hidden risks of biological corrosion and providing additional information on how to avoid bacteria that damage ship bilges; The technical leaflet "Biological Corrosion" is focusing on a number of cases where the issue of leaking engine rooms seems to be more and more common these days. 

DESMI gained a solid reputation over the years for selecting exactly the right materials for its products to withstand the damaging effects of harsh environments. Aiming for a small-footprint system that uses a novel approach to ballast water treatment is a combination that has enabled DESMI CompactClean with its ability to kill organisms within just two hours, surpassing the USCG TA tests’ mandatory 24-hour holding time.
