Prof. Dario Boote (University of Genoa), Mr Gianmarco Vergassola (University of Genova)22/06/2018, 09:00Yacht, pleasure craft design and inland vessels designPaperThe growing increase in length of super and megayachts has driven structural designer to adopt longitudinal layouts as a main point in the structural scantlings. By the way, the optimization of weights, strength, deformations and dynamic behaviour has to be assessed one off for each new units because of peculiar and unique characteristics of each vessel. For this assessment, in particular...Go to contribution page

Dr Pasqualino Corigliano (Department of Engineering, University of Messina)22/06/2018, 09:15Structural design & production technologyPaperWelded joints in ship structures are subject to several variable loadings which may lead to fracture after a relatively low number of cycles. This behaviour is not always fully described by high-cycle fatigue predictions, so low-cycle fatigue has also to be assessed, considering plastic deformation. Local approaches, mainly based on local displacement and strain measurements by strain gauges,...Go to contribution page

Dr Vincenzo Piscopo (The University of Naples "Parthenope")22/06/2018, 09:30Structural design & production technologyPaperThe assessment of plating ultimate strength with pitting corrosion wastage is a basic issue for the proper scantling and design of ship structures. In the past, several nonlinear FE analyses have been performed to investigate the incidence of pitting degree and corrosion depth on plating ultimate strength, with the main aim of providing some approximate formulations, useful at least in a...Go to contribution page

Dr Pasqualino Corigliano (Department of Engineering, University of Messina)22/06/2018, 09:45Structural design & production technologyPaperAluminum superstructures and common steel hull connections are of fundamental importance in ships. Traditionally they were performed by riveting, leading to corrosion phenomena and stress concentration sites. Structural transition joint obtained by explosion welding can overcome these problems giving a good compromise in terms of mechanical strength and corrosion resistance. This study...Go to contribution page

Prof. TOMMASO COPPOLA (University of Naples)22/06/2018, 10:00Structural design & production technologyPaperThe accurate prediction of wave-induced forces and moments on a hull operating in severe weather conditions plays an important role in assessing ship structural strength. For ships prone to large variation of the submerged hull in wave, wave-induced loads could be influenced by the development of parametric roll. This concept is based on the evidence that the combination of all the ship...Go to contribution page

Dr Marina Delucchi (University of Genova, DICCA)22/06/2018, 11:15Environment protection, electric system and ship energy efficiencyPaperTargets of the surface treatments of marine hulls have always been to preserve the structural capacity of the hull envelope and to maintain a smooth and clean external surface, thus minimizing the frictional component of motion resistance. These objectives are pursued since a couple of millennia by fighting the chemical and biological phenomena inducing various forms of degradation in the...Go to contribution page

Mrs Giada Kyaw Oo D'Amore (Engineering and Architecture Department, University of Trieste)22/06/2018, 11:30Naval ships design & technologyPaperAn innovative acoustic and thermal insulating foam was developed starting from fibreglass waste. In this work, the thermo-mechanical response of a fire door containing the foam as insulating material is considered and also the acoustic properties are investigated. In order to comply with the certification process provided by 2010 FTP Code, fire doors must undergo a standard fire test where a...Go to contribution page

Mrs Serena Bertagna (University of Trieste)22/06/2018, 11:45Ship propulsion, machinery and systemsPaperMarine engine industry researches for continuous improvement of efficiency and performance. Currently, all components of marine engines are made in metallic alloys. To reduce costs and weight, new materials for non-structural components must be identified. The new materials, e.g., nano-engineered thermoplastic polymers (NETP), will allow additional benefits due to drastic weight reduction and...Go to contribution page

Mr Claudio Moscoloni (Politecnico di Torino), Mr Marco Fontana (Politecnico di Torino)22/06/2018, 12:00Yacht, pleasure craft design and inland vessels designPaperIn racing boat design, the research is moved to find always the best compromise between performance and safety. The present work focuses on the description of the structural design cycle used by Polito Sailing Team during the realization of its new skiff, a high-performance sailing dinghy, built mainly with natural composite material like balsa wood and flax fiber. The whole boat was...Go to contribution page

Prof. Alberto Marinò (University of Trieste)22/06/2018, 12:15Yacht, pleasure craft design and inland vessels designPaperIn the last few years, the International and National attention to environmental sustainability has increased, even in shipbuilding. This aim can be achieved through various manners, for example by green propulsion (hybrid propulsion), by containment of spills and by studying the life cycle of vessels. About the last one, the problem of disposal of ships at the end of life is of high...Go to contribution page
