Sažetak
One of major design requirements for any marine structure (ship or offshore facility) is to have reasonably long and safe operational life cycle without any catastrophic failure. However, failures still occur causing financial losses and threating human lives, especially in modern structures with reduced weight but increased load carrying capacity. Engineering practice distinguishes usually one or few causes of failure: excessive force and/or temperature induced elastic deformation, yielding, fatigue, corrosion, creep, etc. Therefore, as a first step, it is important to identify potential threats that can affect integrity of marine structures. In order to understand the causes of failures, structure’s load response, failure process, possible consequences and methods to cope with and prevent failures, it is important to educate marine engineers about such problems. Probably the most suitable way of transferring knowledge would be learning from actual examples from engineering practice. Research on this topic includes: identifying potential threats affecting marine structural integrity, analyzing various cases of failures using experimental and numerical approach, assessing structural critical points that could serve as a root of failure, formation of a database comprised of elaborated case studies that can be used in the education worldwide, disseminating results and promoting open access to the database. This paper serves as a progress report of the first part of the ongoing IAMU research project for 2017 where the causes of typical failures in marine structures are determined and critical review of previously conducted researches on similar topics is outlined. Further, results of experimental and numerical failure analysis of typical failures in maritime structures are presented along with directions for future use and database forming.
