of the major contributors to the survivability of a surface combatant is her reduced vulnerability to weapon effects and as such the ship's damage stability characteristics determine a ship's ability to resist the consequences of possible flooding, namely to not capsize and/or sink. There are serious concerns about the limitations of the current semiempirical deterministic criteria in which a combatant's damage stability is assessed upon. This paper details a comparison between the current approach and a newly presented probabilistic approach with the aim of determining which will result in a more accurate way of estimating the level of survivability of a particular design. A study is also presented in which the maximum damage length used in the naval ship assessment is increased to merchant ship standards of 0.24Lbp.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="a640304f98b92fef91842e0cef8eff15" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112684163,"asset_id":116598932,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112684163/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598932"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598932"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598932;

Employed methods include a fully empirical formula, a semi-empirical asymptotic formula, a potential flow, 3D panel method and a CFD code. Each of them requires a different level of detail for the hull form and this enables the application to various practical scenarios. The developed software tools are here validated against recently obtained model experiments data from MARIC. Developed tools are now integrated in the design software platform of MARIC and are used in the optimisation of ship design.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598928"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598928"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598928;

The percentage resistance-increase in waves against experimentally measured calm water resistance data was estimated by use of two alternative empirical formulas, namely one proposed by the authors and the other one as recommended by ITTC. The obtained results clearly show that the percentage resistance-increase and the associated (involuntary) speed loss are strongly dependent on ship's absolute size, loading condition and the operating seaway conditions and they can be satisfactorily quantified. This should be taken into account in the ship design process, when determining the sea margin for the selection of the machinery and propulsion system, when analysing sea trials and/or when preparing scaled model experiments to assess ship's performance in realistic seaway scenarios.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="653797489d1e1fb184387f1740a58518" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112684196,"asset_id":116598922,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112684196/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598922"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598922"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598922;

The data was enhanced by unpublished data from joint industry projects. Using this newly established database consisting of about 3,000 data points for 130 ships of different type and size, we develop an empirical formula for approximating the added resistance in regular waves of arbitrary heading. For the added resistance due to diffraction effect, we updated Faltinsen et al.&#39;s (1980) asymptotic approach and introduced several semi-empirical parameters to approximate the added resistance in waves of various headings. The limited ship draft effect is examined analytically, while the hull form effects are taken into account empirically by regression of available data. For the radiation effect, the maximum value of added resistance and the corresponding wavelength for the various wave headings are determined by regression analysis of the experimental data. The developed formula is verified by application to typical ship types and sizes, both in the design and ballast conditions, at both design and low speeds. An error analysis for the various tested scenarios shows that the performance of the developed formula is satisfactory.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598920"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598920"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598920;

Relevant research work is in the frame of recent IMO-MEPC.232(65) EEDI guidelines for the estimation of minimum powering of ships in adverse weather conditions calling for suitable level 1 methods. We consider the effect of main characteristics of ship׳s hull form, with best fitting of available experimental data for different types of hull forms. A proposed new semi-empirical formula is simplified to the extent that it can be readily calculated using as input merely the speed and main characteristics of the ship and of the wave environment. Extensive validations of the proposed simplified formula for various ship hulls in both regular and irregular waves were carried out and compared to other comparable methods and more complicated approaches to the determination of the added resistance in head waves.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598919"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598919"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598919;

In this work, the influence of wind and wave on ship resistance is calculated using the methods recommended by ITTC [16]. The influence of fouling on resistance is predicted by the method of Granville [18,19], while the influence of fouling on propeller performance is predicted by the method discussed at ITTC [20]. The seaway conditions are derived by onboard monitored data while the hull and propeller are assumed to be in line with practical observations. All the implemented methods have strong background in theoretical and experimental studies, and are easy-to-use and fast in execution. A case study is presented to demonstrate the methodology. This work is expected to support ship owners, operators, and designers in determining the powering margins in the frame of preliminary ship design.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598914"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598914"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598914; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=116598914]").text(description); $(".js-view-count[data-work-id=116598914]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 116598914; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='116598914']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=116598914]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":116598914,"title":"A Fast and Transparent Method for Setting Powering Margins in Ship Design","internal_url":"https://www.academia.edu/116598914/A_Fast_and_Transparent_Method_for_Setting_Powering_Margins_in_Ship_Design","owner_id":27233116,"coauthors_can_edit":true,"owner":{"id":27233116,"first_name":"Apostolos","middle_initials":null,"last_name":"Papanikolaou","page_name":"ApostolosPapanikolaou","domain_name":"ntua","created_at":"2015-03-04T16:47:58.145-08:00","display_name":"Apostolos Papanikolaou","url":"https://ntua.academia.edu/ApostolosPapanikolaou"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="116598913"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/116598913/Rational_processing_of_monitored_ship_voyage_data_for_improved_operation"><img alt="Research paper thumbnail of Rational processing of monitored ship voyage data for improved operation" class="work-thumbnail" src="https://attachments.academia-assets.com/112684195/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/116598913/Rational_processing_of_monitored_ship_voyage_data_for_improved_operation">Rational processing of monitored ship voyage data for improved operation</a></div><div class="wp-workCard_item"><span>Applied Ocean Research</span><span>, Nov 1, 2020</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">This paper presents a method for the rational processing of ship voyage data for improved ship op...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">This paper presents a method for the rational processing of ship voyage data for improved ship operation. The proposed approach is based on a physical modeling method, in which the ship resistance-propeller-engine model is first developed by using available ship information and basic hydrodynamics. For the analysis of operational scenarios in realistic environmental conditions, seaway data are retrieved from WaveWatchIII® hindcast (Tolman, 2002; WAVEWATCH, 2020). The added resistances due to wind is predicted using a standard method recommended by ITTC and the added resistance in waves using a newly developed semi-empirical method of Liu and Papanikolaou (2020). Then, the recorded speed-power data is projected to the calm water condition based on the resistance and thrust identity method. In a second step, we apply simple, yet rational, filtering criteria to filter out the data points polluted by ship's accelerations, the rate of change of course, as well as wave conditions. The developed processing and filtering method is applied to the analysis of the monitored data of three voyages of a chemical carrier and the obtained results are discussed. The prospects of extending the presented method to the study of a time-varying ship speed performance and fuel consumption analysis procedure, in which hull fouling can be studied, is briefly outlined.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d97df88226c53eb7c11ebbcb43450cc9" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112684195,"asset_id":116598913,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112684195/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598913"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598913"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598913;

Up to now, the consideration of sea and weather conditions has been implicitly accounted for in a naval ship's damaged stability assessment. This paper outlines a probabilistic approach to assessing a naval ship's damage stability, in which some of the limitations of the currently used damage stability criteria are identified, including the validity of the assumption of moderate sea states at the time of damage. An investigation into the operability of a frigate design found that there is a significant increase in the risk of a ship's loss when changing the operational area from the North Atlantic to the North Pacific. A remarkable additional finding of the study showed that the assumed distribution for the damage penetration has no significant effect on the ship's survivability due to the way modern combatants are designed.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="fa2186463fd20bf5c176a7d17e68d55f" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112684157,"asset_id":116598912,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112684157/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598912"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598912"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598912;

There are serious concerns about the limitations of the current semiempirical deterministic criteria in which a combatant's damage stability is assessed upon. This paper details a comparison between the current approach and a newly presented probabilistic approach with the aim of determining which will result in a more accurate way of estimating the level of survivability of a particular design.

Employed methods include a fully empirical formula, a semi-empirical asymptotic formula, a potential flow, 3D panel method and a CFD code. Each of them requires a different level of detail for the hull form and this enables the application to various practical scenarios. The developed software tools are here validated against recently obtained model experiments data from MARIC. Developed tools are now integrated in the design software platform of MARIC and are used in the optimisation of ship design.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598928"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598928"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598928;

The percentage resistance-increase in waves against experimentally measured calm water resistance data was estimated by use of two alternative empirical formulas, namely one proposed by the authors and the other one as recommended by ITTC. The obtained results clearly show that the percentage resistance-increase and the associated (involuntary) speed loss are strongly dependent on ship's absolute size, loading condition and the operating seaway conditions and they can be satisfactorily quantified. This should be taken into account in the ship design process, when determining the sea margin for the selection of the machinery and propulsion system, when analysing sea trials and/or when preparing scaled model experiments to assess ship's performance in realistic seaway scenarios.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="653797489d1e1fb184387f1740a58518" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112684196,"asset_id":116598922,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112684196/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598922"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598922"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598922;

The data was enhanced by unpublished data from joint industry projects. Using this newly established database consisting of about 3,000 data points for 130 ships of different type and size, we develop an empirical formula for approximating the added resistance in regular waves of arbitrary heading. For the added resistance due to diffraction effect, we updated Faltinsen et al.&#39;s (1980) asymptotic approach and introduced several semi-empirical parameters to approximate the added resistance in waves of various headings. The limited ship draft effect is examined analytically, while the hull form effects are taken into account empirically by regression of available data. For the radiation effect, the maximum value of added resistance and the corresponding wavelength for the various wave headings are determined by regression analysis of the experimental data. The developed formula is verified by application to typical ship types and sizes, both in the design and ballast conditions, at both design and low speeds. An error analysis for the various tested scenarios shows that the performance of the developed formula is satisfactory.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598920"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598920"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598920;

Relevant research work is in the frame of recent IMO-MEPC.232(65) EEDI guidelines for the estimation of minimum powering of ships in adverse weather conditions calling for suitable level 1 methods. We consider the effect of main characteristics of ship׳s hull form, with best fitting of available experimental data for different types of hull forms. A proposed new semi-empirical formula is simplified to the extent that it can be readily calculated using as input merely the speed and main characteristics of the ship and of the wave environment. Extensive validations of the proposed simplified formula for various ship hulls in both regular and irregular waves were carried out and compared to other comparable methods and more complicated approaches to the determination of the added resistance in head waves.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598919"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598919"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598919;

In this work, the influence of wind and wave on ship resistance is calculated using the methods recommended by ITTC [16]. The influence of fouling on resistance is predicted by the method of Granville [18,19], while the influence of fouling on propeller performance is predicted by the method discussed at ITTC [20]. The seaway conditions are derived by onboard monitored data while the hull and propeller are assumed to be in line with practical observations. All the implemented methods have strong background in theoretical and experimental studies, and are easy-to-use and fast in execution. A case study is presented to demonstrate the methodology. This work is expected to support ship owners, operators, and designers in determining the powering margins in the frame of preliminary ship design.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598914"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598914"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598914; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=116598914]").text(description); $(".js-view-count[data-work-id=116598914]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 116598914; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='116598914']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=116598914]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":116598914,"title":"A Fast and Transparent Method for Setting Powering Margins in Ship Design","internal_url":"https://www.academia.edu/116598914/A_Fast_and_Transparent_Method_for_Setting_Powering_Margins_in_Ship_Design","owner_id":27233116,"coauthors_can_edit":true,"owner":{"id":27233116,"first_name":"Apostolos","middle_initials":null,"last_name":"Papanikolaou","page_name":"ApostolosPapanikolaou","domain_name":"ntua","created_at":"2015-03-04T16:47:58.145-08:00","display_name":"Apostolos Papanikolaou","url":"https://ntua.academia.edu/ApostolosPapanikolaou"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="116598913"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/116598913/Rational_processing_of_monitored_ship_voyage_data_for_improved_operation"><img alt="Research paper thumbnail of Rational processing of monitored ship voyage data for improved operation" class="work-thumbnail" src="https://attachments.academia-assets.com/112684195/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/116598913/Rational_processing_of_monitored_ship_voyage_data_for_improved_operation">Rational processing of monitored ship voyage data for improved operation</a></div><div class="wp-workCard_item"><span>Applied Ocean Research</span><span>, Nov 1, 2020</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">This paper presents a method for the rational processing of ship voyage data for improved ship op...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">This paper presents a method for the rational processing of ship voyage data for improved ship operation. The proposed approach is based on a physical modeling method, in which the ship resistance-propeller-engine model is first developed by using available ship information and basic hydrodynamics. For the analysis of operational scenarios in realistic environmental conditions, seaway data are retrieved from WaveWatchIII® hindcast (Tolman, 2002; WAVEWATCH, 2020). The added resistances due to wind is predicted using a standard method recommended by ITTC and the added resistance in waves using a newly developed semi-empirical method of Liu and Papanikolaou (2020). Then, the recorded speed-power data is projected to the calm water condition based on the resistance and thrust identity method. In a second step, we apply simple, yet rational, filtering criteria to filter out the data points polluted by ship's accelerations, the rate of change of course, as well as wave conditions. The developed processing and filtering method is applied to the analysis of the monitored data of three voyages of a chemical carrier and the obtained results are discussed. The prospects of extending the presented method to the study of a time-varying ship speed performance and fuel consumption analysis procedure, in which hull fouling can be studied, is briefly outlined.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d97df88226c53eb7c11ebbcb43450cc9" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112684195,"asset_id":116598913,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112684195/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598913"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598913"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598913;

Up to now, the consideration of sea and weather conditions has been implicitly accounted for in a naval ship's damaged stability assessment. This paper outlines a probabilistic approach to assessing a naval ship's damage stability, in which some of the limitations of the currently used damage stability criteria are identified, including the validity of the assumption of moderate sea states at the time of damage. An investigation into the operability of a frigate design found that there is a significant increase in the risk of a ship's loss when changing the operational area from the North Atlantic to the North Pacific. A remarkable additional finding of the study showed that the assumed distribution for the damage penetration has no significant effect on the ship's survivability due to the way modern combatants are designed.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="fa2186463fd20bf5c176a7d17e68d55f" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112684157,"asset_id":116598912,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112684157/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116598912"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116598912"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116598912;

The main motivation to use risk-based approaches is twofold: implement a novel ship design which is considered safe but - for some formal, regulatory reason - cannot be approved today and/or rationally optimise an existing design with respect to safety, without compromising on efficiency and performance. It is a clear direction that all future technological and regulatory (International Maritime Organisation) developments regarding ship design and operation will go through risk-based procedures, which are known and well established in other industries (e.g. nuclear, aviation).<br />The present book derives from the knowledge gained in the course of the project SAFEDOR (Design, Operation and Regulation for Safety), an Integrated Project under the 6th framework programme of the European Commission (IP 516278). The book aims to provide an understanding of the fundamentals and details of the integration of risk-based approaches into the ship design process. The book facilitates the transfer of knowledge from recent research work to the wider maritime community and advances scientific approaches dealing with risk-based design and ship safety.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="22888106"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="22888106"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 22888106; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=22888106]").text(description); $(".js-view-count[data-work-id=22888106]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 22888106; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='22888106']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=22888106]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":22888106,"title":"Risk-Based Ship Design - Methods, Tools and Applications","internal_url":"https://www.academia.edu/22888106/Risk_Based_Ship_Design_Methods_Tools_and_Applications","owner_id":27233116,"coauthors_can_edit":true,"owner":{"id":27233116,"first_name":"Apostolos","middle_initials":null,"last_name":"Papanikolaou","page_name":"ApostolosPapanikolaou","domain_name":"ntua","created_at":"2015-03-04T16:47:58.145-08:00","display_name":"Apostolos Papanikolaou","url":"https://ntua.academia.edu/ApostolosPapanikolaou"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="22887712"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/22887712/Ship_Design_Methodologies_of_Preliminary_Design"><img alt="Research paper thumbnail of Ship Design - Methodologies of Preliminary Design" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" rel="nofollow" href="https://www.academia.edu/22887712/Ship_Design_Methodologies_of_Preliminary_Design">Ship Design - Methodologies of Preliminary Design</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">This book deals with ship design and in particular with methodologies of the preliminary design o...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">This book deals with ship design and in particular with methodologies of the preliminary design of ships.
