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.

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.

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.

Creator An entity primarily responsible for making the resource Gasparotti, Carmen Rusu, Liliana Date A point or period of time associated with an event in the lifecycle of the resource 2014-06-23 Description An account of the resource This work presents a methodology for the evaluation of the vessels operability in the basin of the Black Sea. 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.

Panneer Srinivasan, Nagan Date A point or period of time associated with an event in the lifecycle of the resource 2014-12-18 Description An account of the resource Tension Leg Platforms (TLPs) are one of the reliable structures for offshore industry in deep waters because of its motion characteristics in heave, roll and pitch degrees of freedom. Heave motion is very important in offshore facilities and have to kept as minimum as possible. As the water depth increases TLPs suffers from some limitations and hence has to be modified to cater to deeper waters. One such concept proposed is Tension Based Tension Leg Platform (TBTLP). In this paper, experimental investigations carried out on a scaled model of a Tension Based Tension Leg Platform in regular waves are reported. This is the first ever experiments that was carried out on a scaled model of the new concept. To investigate the effect of Tension Base, experiments were also conducted on the TLP (without Tension Base) in two different water depths. RAOs have been compared for surge and heave dof of TLP and TBTLP. Numerical modeling of the TLP and TBTLP responses using ANSYS AQWA software are included as well for comparisons.DOI: http://dx.doi.org/10.3329/jname.v11i2.17341 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/17341 10.3329/jname.v11i2.17341 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/17341/14570 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 2 (2014); 105-116 2070-8998 1813-8535 Subject The topic of the resource Tension leg platorm Tension Base Response amplitude operator (RAO) Modeling Model Tests Regular wave Title A name given to the resource Experimental investigations on tension based tension leg platform (TBTLP) 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.

A magnetic field of uniform strength is assumed to be applied normal to the plate. The equations governing the fluid flow which are highly nonlinear are reduced to linear by using perturbation method and have been solved subject to the relevant boundary conditions. It is noted that the velocity of the fluid is increased as Soret number and suction parameter increase, whereas reverse phenomenon is observed in case of magnetic field strength and sink strength.

Creator An entity primarily responsible for making the resource Shameem, B M Anantha Subramanian, V Date A point or period of time associated with an event in the lifecycle of the resource 2014-06-22 Description An account of the resource The modelling of sea environment is important in designing an effective motion control system for any marine vehicle. Inadequate representation of the components of a typical random sea might lead to poor performance of the control system. A multiple output system such as the one having components of wave elevation and slope, facilitates designing the control system taking into account the different degrees of freedom. The method of modelling the sea environment presented here, provides the basis for the design of motion control systems for multiple degree of freedom cases, which give rise to excitation forces and moments acting on the marine vehicle. The method used here models the sea environment using Gaussian white noise and shaping filter to generate a multiple output form of the random sea state.  In the first step a given standard wave spectrum is approximated using a rational polynomial, the coefficients of the polynomial are obtained by least square fitting method to best match the spectrum. The established rational polynomial is then decomposed to get the transfer function of the shaping filter. The wave slope spectrum is similarly approximated using the same rational polynomial. The transfer functions of the two components of amplitude and slope,  representing the filters are combined to generate a state space form. Using the white noise as input, the state space form obtains the wave elevation and slope as outputs. By performing spectral analysis using Welch method, the quality of the obtained output is checked against the targetted spectrum. The application of the simulated wave slope spectrum in a closed loop state space model is demonstrated as applied to  the roll stabilization characteristics of a stationary ship using a passive tank.DOI: http://dx.doi.org/10.3329/jname.v11i1.17768 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/17768 10.3329/jname.v11i1.17768 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/17768/13336 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 1 (2014); 29-38 2070-8998 1813-8535 Subject The topic of the resource Shaping filter White noise Rational polynomial Least square fitting State space model Title A name given to the resource Sea wave modelling for motion control applications 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 flow is permeated by a uniform transverse magnetic field. A scaling group of transformations is applied to the governing equations. The system remains invariant due to some relations among the parameters of the transformations. After finding three absolute invariants, a third-order ordinary differential equation corresponding to the momentum equation, and two second-order ordinary differential equations corresponding to energy and diffusion equations are derived. The coupled ordinary differential equations along with the boundary conditions are solved numerically. The effects of various parameters on velocity, temperature and concentration fields as well as skin-friction, Nusselt number and Sherwood number are presented graphically and in tabulated form.
