Abstract

A decade ago, the authors introduced the concept of residual strength-damage index diagrams to facilitate rapid predictions of buckling collapse in damaged structures. They demonstrated this approach with an example focused on predicting the collapse of hull girders. [Paik JK, Kim DK, Park DH, Kim HB, Kim MS. 2012b. A New Method for Assessing the Safety of Ships Damaged by Grounding. Int J Marit Eng. 154:A1–A20.]. This paper is a sequel to the 2012 paper by updating the grounding damage data used for the diagrams with more ships in types and sizes, where a total of 12 ships for three different types with four sizes per type are considered: oil tankers (Panamax, Aframax, Suezmax and VLCC), bulk carriers (Handysize, Supramax, Kamsarmax, Capesize), and container ships (3,500TEU, 5,000TEU, 7,500TEU and 13,000TEU). Literature reviews are also made to gain insights on the hull girder collapse of grounded ships, which can be implemented into the updated diagrams. It is confirmed that the proposed methodology can be useful in predicting the hull girder collapse of grounded ships at an earlier stage so that the best timely rescue schemes can be developed to prevent unwanted consequences after grounding, such as casualties, sinking and marine pollution.
