Statistical properties of bulk carrier longitudinal strength

Incidence of Pitting Corrosion Wastage on the Hull Girder Ultimate Strength

“…4, is the Capesize single side skin bulk carrier, analysed in two past reports by the International Ship Structure Committee (ISSC 2000(ISSC , 2012. The ship was also taken as reference vessel in several research studies, carried out in the last years by Moan (2008, 2009), Shu and Moan (2012), Campanile et al (2014Campanile et al ( , 2015, Gordo (2017), Kefal et al (2018), Piscopo andScamardella (2019), among others. The hull girder section scheme is reported in Figure 2, while the ship main data are listed in Table 1.…”

“…Corrosion wastage is one of the key factors to be accounted in the design process of new ships and in the structural health assessment of aged structures, in order to keep both local and global strength check criteria satisfied over time and ensure safety of navigation. Really, age-related effects were not explicitly accounted in the ship design up to the 1980s, as both local and global scantlings were mainly based on Rule formulas, implicitly accounting for corrosion wastage, thanks to the experience gained on in service ships (Campanile et al 2014). Nevertheless, in the last decades, the interest in developing a more rational approach, devoted to assessing the structural degradation of ships over time, grew fast as proved by the variety of research activities, experimental campaigns and corrosion measurements carried out throughout the world (Herring and Titcomb 1981;Thayamballi et al 1987;Guedes Soares and Garbatov 1999;Paik et al 2003a, b;Saad-Eldeen et al 2013).…”

Comparative analysis among deterministic and stochastic collision damage models for oil tanker and bulk carrier reliability

“…The double hull oil tanker and single side bulk carrier, benchmarked for the first time by the ISSC (2000) Special Task Committee VI.2, re-analysed in the ISSC (2012) report and widely investigated in the past by Amlashi and Moan (2008) and Campanile et al (2014Campanile et al ( , 2015Campanile et al ( , 2016a among others, are assumed as test cases for reliability analysis in damage conditions, following a collision event. Ship main dimensions are listed in Table 2, while Fig.…”

“…Hull girder residual strength is determined as detailed in Sub-section 3. The double hull oil tanker and single side bulk carrier, benchmarked for the first time by the ISSC (2000) Special Task Committee VI.2, re-analysed in the ISSC (2012) report on hull girder ultimate strength and widely investigated in the past by Amlashi and Moan (2008) and Campanile et al (2014Campanile et al ( , 2015Campanile et al ( , 2016a among others, are assumed as test cases for reliability analysis in damage conditions, following a collision event. In this respect, as yield strength follows the lognormal distribution, with mean value 10% higher than the Rule one, and 0.08/0.06 COVs for mild/ high-tensile steels, respectively (Fjeld, 1978;Hart et al, 1985), Monte Carlo simulation is expected to overestimate sagging/hogging residual strength mean values by about 10%, as regards the IACS (2015b) reliability model.…”

Local Monte Carlo Method for Fatigue Analysis of Coarse-Grained Metals with a Nanograined Surface Layer

“…For instance, Bouhamida et al combined MCS to study the distribution of stress concentration for each fiber [28]. Campanile et al applied MCS with Weibull distribution to investigate statistical properties of the hull girder section modulus and ultimate strength [29]. Based on the scatter of concrete tensile strength and bond strength, Hartig and Häussler-Combe employed MCS to study the statistics of crack widths [30].…”
