Collision Analysis of a Self Propelled Oil Barge’s (SPOB) Using Finite Element Method

Abstract

Impact is a collision between two objects of force in a short time of period. Research on hull impact SPOB 3500 DWT using element method up to Ansys Explicit Dynamics software. In this study, two variations models were used, when impact where the jetty is not equipped with fenders and jetty equipped with fenders. Value of plate thickness is 10 mm, and with a speed variation of 0.5 m/s 1 m/s and 2 m/s. Using element-based applications to determine damage based on deformation values on the SPOB 3500 DWT body when crashing jetty and hull damage after jetty that is not equipped with fenders and fenders equipped at speed variations. . The force values that have been calculated with speeds of 0.5 m/s, 1m/s and 2m/s are 3.52 MN, 7.04 MN, and 14.07 MN, respectively. With the deformation values in the model of the ship hitting a jetty that is not equipped with fenders which are calculated at a speed of 0.5 m/s, 1m/s and 2m/s, respectively, they are 0.53011 mm, 1.0594 mm, and 2.1184 mm. And the value of deformation on the model of the ship hitting a jetty equipped with fenders which is calculated at a speed of 0.5 m/s, 1m/s and 2m/s, respectively, is 0.36511 mm, 0.7357 mm, and 1.4939 mm.

Numerical Investigation of the Laying of Airbag Arrangements on Launching Barges

“…The study of the response of the ship's structure when it experiences a collision both during launch and under other conditions is very important to study because it has implications for the shape of the ship when it is in the water, which in fact significantly affects performance when operating. analyzed ship collisions using FE-based numerical simulations [5]. investigated local stresses in the construction of ship decks using a finite element (FE)based numerical simulation method [6].…”
