ULTIMATE LIMIT STATE PERFORMANCE OF 300K DOUBLE HULL OIL TANKER STRUCTURES: PRE-CSR VERSUS CSR DESIGNS


Abstract eng:
The aim of the present paper is to evaluate the ultimate limit state (ULS) performance of hypothetical 300k double hull oil tanker structures designed by IACS CSR (Common Structural Rules) method, compared with the similar-class/type tanker structure designed by IACS pre-CSR method. The ultimate strengths of stiffened plate structures in deck and bottom parts, and hull girders against vertical bending moment, are computed for the two designs, and the resulting computations are compared. ALPS/ULSAP and DNV PULS programs are used for the ultimate limit state assessment of stiffened plate structures, and ALPS/HULL program is employed for the progressive hull collapse analysis. ABAQUS nonlinear FEA method using more refined technology of the ULS analysis is also used for computing stiffened panel ULS. The insights and developments obtained from the present study are addressed.
