Development of an empirical formula for residual strength assessment to prevent sequential events of grounded oil tankers

Author(s): Seung Jun Baek, Sang Jin Kim, Jeom Kee Paik, Jung Min Sohn

Abstract
The aim of this study is to develop a rapid calculation technique of the residual strength in order to prevent sequential events under grounding ccidents. Very Large Crude-Oil Carrier (VLCC), Suezmax, and Aframax double hull oil tankers carrying large quantities of crude oil were selected for target structures. The rock geometries are chosen from the published regulation by Marine Pollution Treaty (MARPOL) of the International Maritime Organization (IMO). Oceanic rocks as the most frequently encountered obstruction with ships are applied in this work. Damage condition was predicted using ALPS/HULL program based on grounding scenario with selected parameters, i.e. depth of penetration, damage location and tanker type. The results of the scenarios are quantified to form an empirical formula which can evaluate the residual strength. The proposed formula is validated by applying a series of random grounding scenarios.
