ULTIMATE LIMIT STATE PERFORMANCE OF 170K BULK CARRIER STRUCTURES: PRE-CSR VERSUS CSR DESIGNS

Abstract eng:
The aim of the present paper is to evaluate the ultimate limit state (ULS) performance of 170k bulk carrier structures designed by IACS CSR (Common Structural Rules) method, compared with the similar-class/type bulk carrier structure designed by IACS pre-CSR method. The ultimate strengths of stiffened plate structures in deck, side and bottom parts, and hull girders against vertical bending moment, are computed for the two designs, and the resulting computations are compared. ALPS/ULSAP program is used for the ultimate limit state assessment of stiffened plate structures, and ALPS/HULL program is employed for the progressive hull collapse analysis. The insights and developments obtained from the present study are addressed.
