HULL GIRDER ULTIMATE STRENGTH OF A DAMAGED OIL TANKER
Within the scope of the presented work a hull girder ultimate strength analyses of the double hull oil tanker structures damaged by the collision or grounding is performed. An incremental-iterative progressive collapse analysis method prescribed by the forthcoming IACS Harmonized Common Structural Rules (H-CSR) is used for determination of the ultimate (vertical) bending moments and collapse sequences of the considered structures. Three characteristic variants of the oil tanker main frame cross sections of a different geometry and size (Aframax, Suezmax and VLCC) are considered. The position of a ship’s side and/or bottom damage is defined in accordance with the IACS H-CSR. Proposed analytical formulations of the relationship between reduction of the hull girder ultimate bending moment (with respect to the undamaged state) and damage size are based on the results of a systematic variation of a ship’s side or bottom damage size. Finally, comparison of the collapse sequences determined for the undamaged and damaged state (defined by IACS H-CSR) of the considered structures is performed.
