... environment. This issue becomes more complicated for the double hull tank cases, since the presence of ballast tanks causes violent small-scale flow motions and mixing inside a narrow space. The following review mainly focuses on the investigation on the oil leaking from damaged DHT. Regardless the dynamic...

... Abstract Onboard investigations for VLCC and LNG carrier were carried out to clarify the deterioration mechanism of coated steel in a water ballast tank (WBT). The degree of deterioration of the coated steel in each area of the WBT was quantified by the assessment scale of the IACS. Analysis...
