Time-varying ultimate strength of aging tanker deck plate considering corrosion effect

An Approach to the Probabilistic Corrosion Rate Estimation Model for Inner Bottom Plates of Bulk Carriers

“…By applying with frequencies presented in Figure 7 (related to a set of 570 measurements data of plate thickness due to corrosion), the positive p -values of this test is obtained only in the following two cases: a) the case of logistic distribution with mean 0.137133 and scale parameter 0.050494. Notice that the above logistic distribution coincides with those obtained in Subsection, 3.2 whose CDF is given by the expression (8).…”

“…In previous research, authors were motivated to investigate corrosion degradation of some specific structural members such as transversal bulkhead of bulk carriers [7] or deck plating of tankers [8,9,10,11], or all structural members (see Paik et al [4,12,13]). …”

Reducing the cost of ballast tank corrosion: an economic modeling approach

“…Indeed, the condition of a ballast tank is not only agedependent but other important factors are involved such as substrate preparation, application conditions, mechanical damages, maintenance and many more. Moreover, when these observations are compared to other, previously published time dependent corrosion models [22][23][24][25][26][27][28], a similarly high variability can be noted for older ships.…”

Ultimate strength of corroded web-core sandwich beams

“…With a proper protection from corrosion, such a situation can be avoided, as presented in this investigation. Even for structural elements directly exposed to water flow, it has been shown that the breakdown of the coating, the most common type of corrosion protection system, takes between 2 and 10 years; see Guo et al [19]. The experiments showed that the efficient protection of ultimate strength can be achieved by several corrosion protection systems.…”
