“…3a indicates that the highest energy was achieved by the bottom plate. In this discussion, the internal energy is determined as a main parameter which reflects the amount of energy that is necessary to plastically deform the involved structures in impact [3,4,10]. More detail observation is conducted on the polar class materials while failure took place.…”

“…Properties of the ice are given as follows: Poisson's ratio n = 0.27, Young's modulus Ex = 1000 MPa and density ρ = 960 kg/m 3 . As indicated in pioneer works [3][4], the failure criterion is necessary to be involved in calculation. The Peschmann criterion [11] is applied in this work which concludes the element length of the engineering models is 150 mm and failure strain for the double-bottom structure is 0.21.…”

The remarkable influence of the global warming to Arctic environment opens a possibility to conduct a voyage from Asia to Europe through the Northern Sea Route (NSR). This option is considered as a decent solution to reduce fuel consumption and increase time efficiency in delivering cargo to the designated destination. However, this alternative comes with a challenge to keep safety of ship structures against an impact with obstacles which are possibly encountered at the Arctic. Solid ice can be considered as a serious threat to the double bottom of ship structures in impact phenomena, especially ship grounding. In this work, a series of grounding calculations are conducted to produce estimation of structural crashworthiness during interaction between double bottom and conical type ice. Material characteristics based on tensile testing of polar class material are applied to calculation and compared with non-polar steel.

Abstract:The impact phenomenon is inseparable part of every physical things, from substantial particle until macrostructure namely ship. In ship collisions, shortperiod load is distributed during impact process from striking ship into struck ship. The kinetic energy that is used to move striking ship is absorbed by struck ship that makes its structure undergoes plastic deformation and failure. This paper presents study that focuses on predicting occurred damage on side hull of struck ship for various impact scenario models. These scenarios are calculated by finite element approach to obtain characteristic on damage, energy as well as load during and after impact processes. The results indicate that the damages on impact to longitudinal components such as main and car decks are smaller than impact to transverse structure components. The damage and deformation are widely distributed to almost side structures including inner structure. The width between outer and inner shells is very affecting the damage mode where the width below the two meters will make inner shell experience damage beyond plastic deformation. The contribution of structure components is proofed deliver significant effect to damage mode and material strengths clearly affect the results in energy and load characteristic.

This work models the effect of an impact phenomenon-namely the interaction between seabed rock and a ship during its operations-on the ship structure. The collision between a tanker vessel with a conical rock is simulated, a scenario that is similar to the famous grounding of the Exxon Valdez oil tanker. The study uses finite element analysis to simulate numerical parameters that are related to structural response and the contours of the ship hull under impact loading. The traditional element-length-to-thickness (ELT) ratio of 10 is recommended in this work. ELT ratios in the range of 11 to 13 are shown to produce similar results in terms of internal energy, contact force, and structural acceleration. Additionally, the analysis time is reduced by approximately 20% for the recommended ELT ratio. This result is very helpful for researchers using finite element analysis to simulate ship accidents, since the mesh size or length of complex structures is used to maintain the efficiency and accuracy of the simulation results.
