Abstract Ship structures while in service are likely to be subjected to age deterioration which actually causes catastrophic structural or total loss especially for bulk carriers. This implies the need to develop advanced technologies which can allow for proper management and control of such age related deterioration. Recently, IMO and classification societies have developed rules and regulations utilizing risk-based methods. The Formal Safety Assessment (FSA) is an example of such developments. In the following study a finite element model is established using commercial software for the fore-end bulkhead of an existing bulk carrier which is subjected to SOLAS XII as a risk control option of formal safety assessment. The main aim of the finite element model is to assess the strength characteristics of the corrugated bulkhead during service time with the reduction of bulkhead plating thickness due to age deterioration according to the corrosion model of Paik (2003) and estimated corrosion rates as in the DNV casualty report. The insights developed from the present study are useful for finding a proper management for structural repair of the bulkhead under consideration taking into account corrosion wastage. |
