Residual ultimate strength of a very large crude carrier considering probabilistic damage extents

Study on the multiparameter monitoring system in the old VLCC for offshore oil storage

“…GUI is the most intuitive interface displayed to the operators, where the data are displayed directly [18] . With the help of GUI interface, the data collected and processed by data acquisition module and data processing module are displayed intuitively.…”

A Risk Assessment of Ships Groundings in Rivers: The Case of Parana River

“…In the aftermath of this and similar incidents, technical and regulatory initiatives have made ships safer; however groundings still occur, and are particularly significant causes of marine pollution. Regulators are particularly concerned regarding crude oil carriers and chemical tankers (Choung et al, 2014). Another area of improvement concerning dry cargo and passenger ships was the introduction of standard international rules in January 2009 (Papanikolaou et al, 2013).…”

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

“…Finally, it must be pointed out that in current analysis possible heelings, due to asymmetric flooding conditions after a collision event, have not been considered, in compliance with the residual strength check provided by CSR-H (IACS, 2015a) and IACS Report on hull girder reliability after damage events (IACS, 2015b). Moreover, the incidence of ship heeling, due to asymmetric flooding conditions, on hull girder residual strength was already investigated by Choung et al (2014) who determined, for several heeling angles in the range 0 e180 , with 15 step, the damage index, namely the residual to ultimate strength ratio. Based on relevant outcomes, it can be gathered that: (i) maximum hull girder strength percentage reduction occurs at 75 for collision events and that (ii) the dependence of damage index on ship heeling is certainly present, even if moderate, and worthy of being further investigated.…”

“…In the same years, due to the growing interest in evaluating ship response in damage conditions, more refined structural models, capable of accurately predicting hull girder sagging/ hogging residual strength, following collision or grounding events, were developed by several researchers (Smith and Pegg, 2003;€ Ozgu ¨ç and Barltrop, 2008;Choung et al, 2012;Alie et al, 2012;Kim et al, 2013;Choung et al, 2014;Campanile et al, 2015, among others), with the main aim of providing a structural model, based on classical incremental iterative method, but capable of satisfying the horizontal bending moment equilibrium equation, in case of asymmetrically damaged cross-sections. At the same time, hull girder reliability in damage conditions was investigated, focussing on limit state functions after collision events (Fang and Das, 2005), operational conditions and hull girder deterioration (Saydam and Frangopol, 2013), incidence of welding residual stresses and material properties on hull girder reliability (Campanile et al, 2015(Campanile et al, , 2016a.…”
