The most important aspect was to obtain a large set of roll restoring moments, for both passive and controlled configurations, which could give a discrete distribution of the roll restoring moments along the entire range of wave frequencies of interest. On a first study, a detailed account of model tests was presented, the method of analyzing the experimental results was discussed, and the experimental data of the U-type tank was compared with results from Lloyd\u2019s linear frequency domain model, where non-linear effects with the amplitude of the forced motions was thoroughly addressed.<\/jats:p>\n               <jats:p>In this paper, the stabilizing effects of the same U-tank installed onboard a typical containership has been first analyzed with two distinct tools: WaMIT wave interaction 3D analysis software, and the two degrees-of-freedom numerical model referred above. In second place, the experimental data of the controlled U-type tank has been compared and contrasted with results from a nonlinear time domain model, where the controller of the air valves has been also included. Therefore, some preliminary conclusions could finally be drawn about the stabilizing effects of U-type tanks as passive and controlled anti-rolling devices.<\/jats:p>","DOI":"10.1115\/omae2012-83501","type":"proceedings-article","created":{"date-parts":[[2013,8,24]],"date-time":"2013-08-24T01:31:43Z","timestamp":1377307903000},"page":"479-490","update-policy":"http:\/\/dx.doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":0,"title":["The Stabilizing Effects of U-Tanks as Passive and Controlled Anti-Rolling Devices"],"prefix":"10.1115","author":[{"given":"Sergio","family":"Ribeiro e Silva","sequence":"first","affiliation":[{"name":"Technical University of Lisbon, Lisbon, Portugal"}]},{"given":"Guillermo","family":"V\u00e1squez","sequence":"additional","affiliation":[{"name":"Technical University of Lisbon, Lisbon, Portugal"}]},{"given":"C.","family":"Guedes Soares","sequence":"additional","affiliation":[{"name":"Technical University of Lisbon, Lisbon, Portugal"}]},{"given":"Adolfo","family":"Mar\u00f3n","sequence":"additional","affiliation":[{"name":"Canal de Experiencias Hidrodin\u00e1micas de El Pardo, Madrid, Spain"}]}],"member":"33","published-online":{"date-parts":[[2013,8,23]]},"event":{"name":"ASME 2012 31st International Conference on Ocean, Offshore and Arctic Engineering","start":{"date-parts":[[2012,7,1]]},"sponsor":["Ocean, Offshore and Arctic Engineering Division"],"location":"Rio de Janeiro, Brazil","end":{"date-parts":[[2012,7,6]]},"acronym":"OMAE2012"},"container-title":["Volume 4: Offshore Geotechnics; Ronald W.
