Estimation of Buckling Response of the Deck Panel in Axial Compression

Abstract

In this work, buckling strength assessment of a deck of a double hull oil tanker is carried out using the non-linear finite element code ADVANCE ABAQUS. The comparisons are performed with the Det Norske Veritas (DNV-GL) PULS (Panel Ultimate Limit State) buckling code for the stiffened panels, DNV-GL Classification Notes (CN) No.30.1 and the DNV-GL Ship Rules. The case studied corresponds to axial compression. Two levels of imperfection tolerances are analyzed, in accordance with the specifications in the DNV-GL Instruction to Surveyors (IS) and the DNV-GL Classification Notes No. 30.1. Both "as built" and DNV-GL Rule "net" dimensions are analyzed. The strength values from ADVANCE ABAQUS and PULS are very close. DNV-GL CN 30.1 is in conservative side, but the strength differences between the "as built" and "net" dimension cases are consistent with the finite element analysis results. This paper gives a brief description of the background for the stiffened panel models used in PULS, and comparison against non-linear FE analysis, and DNV-GL Classification Society Rules. The finite element code ADVANCE ABAQUS is employed in a non-linear buckling analysis of a stiffened deck panel on a double skin tanker that is subjected to a Condition Assessment Program (CAP) hull survey. The aim of the analyses has been to validate and compare the buckling capacity estimates obtained from PULS, and the DNV-GL Ship Rules.

Fractal characteristics of geomorphological heterogeneity in Xisha Islands waters under Multiple Linear Regression

“…Take the phenomenon that we are used to in the sky as an example. When you look up at the sky, you can often see a group of clouds floating in it, which is poetic (Ozguc, 2018). But if you look at the clouds with different telescopes, you will find that the shape of the clouds seems to have nothing to do with the magnification of the telescope.…”

Assessment of Buckling Behaviour on an FPSO Deck Panel

“…The buckling strength assessment of a deck of a doublehull oil tanker was performed by Ozguc [15] using the nonlinear finite element code ADVANCE ABAQUS [9,31]. Comparisons were carried out with the Det Norske Veritas (DNVGL) PULS (Panel Ultimate Limit State) buckling code [23] for the stiffened panels, DNVGL Classification Notes (CN) No.…”
