Reliability-Based Assessment of Damaged Ships

Ship Structure Committee (SSC) seeks specialists interested in participating as members of the Project Technical Committee (PTC) assisting during evaluation of a new research project. This new project will develop a reliability-based analysis procedure for determining survivability, recoverability and operability of damaged ships. The project has not yet been solicited. However, when the proposals are received from prospective contractors, the PTC Chairman will ask participating members to review submitted materials, provide expert input and recommendation of who should be awarded the contract. Further assistance during the research portion of the project will also be required.

The objective of the proposed research is to develop a reliability-based analysis procedure for determining survivability, recoverability and operability of damaged ships, adopting a systematic approach. The wave excitation loads will be predicted by a non-linear method. The experimental study will compare the results obtained from the prediction with those obtained from measurements. The ultimate hull girder strength of damaged ships will then be evaluated considering effects of horizontal bending moment and shear. The reliability of damaged ships will be estimated, and a reliability-based decision format will be developed for damaged ships. Those who are interested in providing their expertise are requested to contact Ms. Jeannette Delaney.
