The approach proposed is based on the results provided by a wave prediction system that was implemented and validated in the Black Sea. This offers a meaningful framework in the assessment of the seakeeping performance for ships operating in different conditions. The aim of the work is to improve the seakeeping performances for various types of ships that sail in the Romanian coastal zones. Two containerships are considered, of 1300TEU and 800TEU respectively, which have however the same displacement. For predicting the ship motions induced by the various wave conditions encountered in the operational area, it is necessary to know the transfer functions for different ship speeds and heading angles. These are computed with a numerical code based on the strip theory. The predicted motions are then compared with the limit values of the relevant seakeeping criteria, considered as the criteria for checking the operability of the ship. By defining the acceptable operating boundaries, the ship behavior in waves can be quantified. The vessel meets the criteria for those combinations wave height-wave period that are below the limit curves. The results are presented as operational maps for the Black Sea basin, allowing the identification of the areas that should be avoided due to unfavorable weather conditions. The methodology proposed herewith can be extended and applied to various marine environments and types of ships.DOI: http://dx.doi.org/10.3329/jname.v11i1.17289 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/17289 10.3329/jname.v11i1.17289 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/17289/13367 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 1 (2014); 55-68 2070-8998 1813-8535 Subject The topic of the resource numerical wave models seakeeping performance containerships operability seakeeping criteria ship responses Title A name given to the resource Prediction of the dynamic responses for two containerships operating in the black sea Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion mathematical and numerical modeling Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

This work is a part of a large framework of numerical simulation and experimentation carried out for blunted head-forms of hemispheric shapes for determination of aero-hydrodynamic coefficients and static stability features. Results are presented for a clean hull-form and with the pin-protuberance, as static axial and circumferential pressure distribution on the surface, calculated at a fixed velocity and at different angle of attacks, under non-cavitating depth and velocity. It is shown that a suitably located short lateral pin has an adequate effectiveness to control pitch maneuver of an underwater hemisphere-cylinder hull-form. In view of that, a suitable pin-height adjustment commensurate to pitch attitude trajectory corrections is a workable idea, and the concept has potential of effective pitch attitude control of the hemisphere-cylinder hull-form.DOI: http://dx.doi.org/10.3329/jname.v11i1.16725 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/16725 10.3329/jname.v11i1.16725 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/16725/13364 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 1 (2014); 93-104 2070-8998 1813-8535 Subject The topic of the resource Autonomous underwater vehicles Hemisphere-cylinder hull-form Axisymmetric hydrodynamic configuration Axial pressure distribution CFD Hydrodynamic force coefficients Static stability.

Four liquid fill levels with static liquid depth, hs, to the length, l of aspect ratio (hs/l) 0.163, 0.325, 0.488 and 0.585, are considered. The energy spectra of sloshing oscillation, their qualitative assessment and the harmonics present in the sloshing oscillation are studied. Frequency –Response amplitude has also been presented. The study reveals that sway excites a particular mode of sloshing (primary harmonic) by fulfilling the resonance conditions and also excites secondary modes. However, the roll motion excites the first mode of sloshing irrespective of the excitation frequencies. The heave motion excites the particular mode which is assumed as an initial perturbation.DOI: http://dx.doi.org/10.3329/jname.v10i2.16215  Format The file format, physical medium, or dimensions of the resource application/pdf application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/16215 10.3329/jname.v10i2.16215 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/16215/12248 https://www.banglajol.info/index.php/JNAME/article/view/16215/26894 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 10 No. 2 (2013); 119-138 2070-8998 1813-8535 Subject The topic of the resource Regular wave perturbation first mode primary resonance parametric resonance barge pitching Title A name given to the resource A numerical study: liquid sloshing dynamics in a tank due to uncoupled sway, heave and roll ship motions Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Creator An entity primarily responsible for making the resource Chandrasekaran, Srinivasan Kumar, Deepak Ramanathan, Ranjani Date A point or period of time associated with an event in the lifecycle of the resource 2013-12-27 Description An account of the resource Tension Leg Platform (TLP) is a taut-moored compliant offshore platform that deploys tethers under high initial pretension to counteract the excess buoyancy. TLPs show large amplitude responses under the encountered lateral forces, which challenges the serviceability of the platform in critical sea states. One of the passive control device i.e. Tuned Mass Damper (TMD) is attempted in the present study to control large amplitude motion of TLPs. In the present study, response control of TLP using single and multiple TMDs is compared. Optimized parameters of multiple tuned mass dampers (MTMD) are obtained using H2 optimization algorithm for the maximum control of the motion of the platform. Based on the studies conducted, it is seen that MTMD systems show better response control in comparison to the single TMD. Higher robustness of the MTMD system is also examined to highlight the use of MTMD over a wide range of excitation frequencies in extreme sea states.DOI: http://dx.doi.org/10.3329/jname.v10i2.16184 Format The file format, physical medium, or dimensions of the resource application/pdf image/jpeg application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/16184 10.3329/jname.v10i2.16184 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/16184/12237 https://www.banglajol.info/index.php/JNAME/article/view/16184/26878 https://www.banglajol.info/index.php/JNAME/article/view/16184/26890 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 10 No. 2 (2013); 149-156 2070-8998 1813-8535 Subject The topic of the resource Tension leg Platform Tuned Mass Damper Multi Tuned Mass Damper Mass ratio Title A name given to the resource Dynamic response of tension leg platform with tuned mass dampers Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Numerical study Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Creator An entity primarily responsible for making the resource Ali, Md Ashim Suzuki, Kazuo Miyauchi, Sou Date A point or period of time associated with an event in the lifecycle of the resource 2013-12-24 Description An account of the resource Due to the increase of maritime transportation volume day by day it is necessary to design a ship hull having large carrying capacity with low resistance. In case of slow moving ships, usually wave breaking occurs in front of bow. A considerable portion of resistance occurs due to the energy dissipation of such wave breaking in case of Ultra Large Block coefficient Ship (ULBS) suggested by the authors. The key objective of this research work is to investigate the relationship between bow wave breaking and free surface disturbance function that may be used as a parameter for numerical prediction of bow wave breaking. In this regard, the experiments and numerical calculations have been carried out for six models of ULBS. From the results, it can be concluded that the wave breaking area in front of bow increases with the increase of surface integral of the square of free surface disturbance function, Froude number and block coefficient.DOI: http://dx.doi.org/10.3329/jname.v10i2.16104  Format The file format, physical medium, or dimensions of the resource application/pdf application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/16104 10.3329/jname.v10i2.16104 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/16104/12239 https://www.banglajol.info/index.php/JNAME/article/view/16104/26879 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 10 No. 2 (2013); 69-80 2070-8998 1813-8535 Subject The topic of the resource Wave breaking Free Surface Disturbance (FSD) function Rankine Source Method Ultra Large Block coefficient Ship (ULBS) Title A name given to the resource Study on bow wave breaking around ultra large block coefficient ship Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The shells were tested for buckling under hydrostatic loading and microstrains as a function of applied hydrostatic pressure were measured. Numerical analysis was performed for critical buckling pressure based on Block Lancoz buckling analysis and for Von-Mises stresses and strains based on static analysis using ANSYS. Von-Mises stresses corresponding to hydrostatic pressures were computed analytically by Reduced Stiffness Matrix method. The numerical results of critical buckling pressure for 10 mm thick vessels showed 7.12 % deviation from the experimental results. The microstrains predicted by FEA were in good agreement with the experimental strains. Von-Mises stresses predicted by FEA agreed well with the analytical computations.DOI: http://dx.doi.org/10.3329/jname.v11i1.16087 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/16087 10.3329/jname.v11i1.16087 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/16087/13333 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 1 (2014); 15-28 2070-8998 1813-8535 Subject The topic of the resource Critical Buckling Pressure FEA Reduced Stiffness Matrix Filament winding Title A name given to the resource Buckling behaviour of underwater vessels by experimental, numerical and analytical approaches Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Quasi-Experimental Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Date A point or period of time associated with an event in the lifecycle of the resource 2013-12-30 Description An account of the resource An analysis is performed to study the thermal radiation and chemical reaction effects on coupled heat and mass transfer by MHD natural convective boundary-layer flow of a micropolar fluid over a permeable truncated cone with variable surface temperature and concentration. A suitable set of dimensionless variables is used to transform the governing equations of the problem into a non-similar form. The resulting non-similar equations have the property that they reduce to various special cases previously considered in the literature. An adequate and efficient implicit, tri-diagonal finite difference scheme is employed for the numerical solution of the obtained equations. Various comparisons with previously published work are performed and the results are found to be in excellent agreement. A representative set of numerical results for the velocity, microrotation, temperature and concentration profiles as well as the local skin-friction coefficient, local wall couple stress, local Nusselt number and the local Sherwood number is presented graphically for various parametric conditions and discussed.DOI: http://dx.doi.org/10.3329/jname.v10i2.15898 Format The file format, physical medium, or dimensions of the resource application/pdf application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/15898 10.3329/jname.v10i2.15898 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/15898/12255 https://www.banglajol.info/index.php/JNAME/article/view/15898/26874 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 10 No. 2 (2013); 157-168 2070-8998 1813-8535 Title A name given to the resource Coupled heat and mass transfer by MHD natural convection of micropolar fluid about a truncated cone in the presence of radiation and chemical reaction Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Date A point or period of time associated with an event in the lifecycle of the resource 2014-06-10 Description An account of the resource Shipbuilding is on the verge of blooming into the major foreign revenue-earning industry in Bangladesh. A number of export-oriented shipyards are developed to deliver different kinds of ships for local and international clients. For designing a ship, model testing facilities are required not only to predict power requirements but also to evaluate its performance in actual sea operation. At present, Bangladesh does not have this facility. Also carrying out model testing is very expensive and time consuming. Therefore, now-a-days most of the shipyards all over the world are using virtual or computational towing tank facility. Due to improvement of solution algorithm for handling non-linear problem and computational infrastructure, computational or virtual towing tank can be used as a replacement of physical towing tank experiments. In the present study, a numerical or computational towing tank technique named WISDAM which is developed at The University of Tokyo, Japan is described with its applicability in perspective of Bangladesh shipbuilding industries.DOI: http://dx.doi.org/10.3329/jname.v11i1.15619 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/15619 10.3329/jname.v11i1.15619 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/15619/13334 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 1 (2014); 1-14 2070-8998 1813-8535 Subject The topic of the resource Computational fluid dynamics RaNS virtual towing tank shipbuilding Title A name given to the resource Prospects of virtual or computational towing tank facility for the shipbuilding industry of Bangladesh Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
