Journals & Books; Help One-way and two-way interactions are computed considering vibration of the hull girder. In the case of one-way interactions, the computed fluid loads affect the structure, but the structural response does not affect the fluid domain solution whereas for the two-way interactions the structural response affects the Cited by: 8. PREDICTION OF SLAMMING CHARACTERISTICS AND HULL RESPONSES FOR SHIP DESIGN. The paper presents a method to predict the necessary information on slamming characteristics and hull responses of a ship at an early design stage using only the ship by: Dynamic Response of Ship hull due to slamming Master’s thesis, NTNU Summary In this thesis full-fledged Finite Element Analysis is done for Free vibration analysis and Dynamic Forced Response Analysis of ship hull due to the slam induced load in sea way. This topic is of concern for ships and offshore structures in terms of safety. For these tw o load cases, the paper compares the hull girder loads, the hull deflection and the stresses, and the accuracy proves the v alidity of this new method.

This particular report deals only with the demand -- or loading -- on the hull girder, but an attempt has been made to fcmmulate it in a manner that is consistent with the above approach. In due course, with the cooperation of the ship structural designer, it is anticipated that . Hull monitoring systems are fitted to acquire, display, and/or record information and then use th at information for decision making to improve operational efficiency and/or safety. As marily ABS is pri interested in the enhanced safety aspects that can be obtained by the correct use . The procedure is easy to use and can be utilized to make quick estimates of the whipping effect on hull girder bending moment and on fatigue load. It could be utilized during the conceptual design phase and to perform a sensitivity study of its variation with main dimensions and operational profiles.

Extreme Hull Girder Loading. in Proceedings of the 14th International Ship and Offshore Structures Congress , Vol. 2 (Eds. Ohtsubo, H. and Sumi, Y.). ISSC , Nagasaki, Japan, pp. , 14th International Ship and Offshore Structures congress , Nagasaki, 01/01/ Considering a hull girder as a beam section under bending, Smith (, ) proposed a simple procedure to calculate the moment–curvature relationship and ultimate strength of a hull girder. The basic assumptions of the Smith method are summarized as follows: 1. The hull cross section is subdivided into a number of subdivisions, such as stiffeners with associated plating and corner. Germanischer Lloyd. The topic of the thesis covers the area of the ultimate strength of the hull girder. The full subject of the thesis is “Hull girder failure of a container ship and of a bulk carrier under combined global and local loads” The task of the thesis is to build a model of the ship and using chosen techniques analyze the. ing the effects on hull girder loads due to slamming. The relation between the magnitude and distribution of the various hydrodynamic loads, and the manner and form in which such information may be used in the context of structural reliability, are also addressed in this paper. T’lmmethods used to find these hydrodynamic loads con-.
