Abstract: Along the Norwegian coastline, an increasing number of reinforced concrete barges are being produced for the local fish farming industry. Since these concrete barges both are being used as living quarters and storage units for equipment and fish feed, strict requirements to safety and performance for such structures exist. So far, however, the requirements to durability and long-term performance have almost exclusively been based on conventional durability requirements in existing concrete codes. Since such requirements frequently have shown to yield unsatisfactory results for concrete structures in marine environments, much research has been carried out over recent years in order to develop a better basis for obtaining a more controlled durability and long-term performance; in particular the introduction of a probability-based durability design has proved to be very valuable. In order to provide more relevant durability data from existing concrete barges, an existing concrete barge was selected for detailed investigations in the field and subjected to a probability-based durability analysis. The results from the investigations carried out after service periods of 12 and 20 years, respectively, demonstrate that requirements based on current concrete codes are not adequate for providing proper durability and long-term performance of such concrete structures.
