Iceberg impact and wave loads were topics in the presentation “Hebron Offshore Concrete Gravity-Based Structure: Novel Design and Construction Techniques,” just one of several presentations kicking off the first part of a two-part session titled “Offshore and Marine Concrete Structures: Past, Present, and Future,” at The Concrete Convention and Exposition, in Québec City, QC, Canada, on March 25, 2019. The Hebron platform is the latest major offshore integrated oil drilling and production platform supported by a concrete gravity-based-structure (GBS). It was successfully installed in the Grand Banks (offshore Newfoundland) in June 2017. The innovative use of non-linear finite element analysis (NLFEA) technique to calculate internal forces was presented. NLFEA was used both for extreme iceberg impact loads on the exterior caisson walls as well as extreme wave impact loading on the shaft. Sponsored by ACI Committee 357: Offshore and Marine Concrete Structures, the session focused on the need for better coordination and synchronization of design, construction, inspection, and maintenance practices. New and emerging technologies related to offshore and marine concrete structures were also highlighted. Presentations included: Design and Construction Overview of Offshore Concrete Gravity-Based-Structures: Past, Present, and Future; Concrete Mixture Design Development for Offshore Structures; Testing and Inspection Techniques for Offshore and Marine Structures; and Performance of Concrete in a Harsh Marine Environment for 25 Years Marine structures were the focus of another session later in the day, titled “Marine Structures—Global Case Studies and Research.” This session highlighted the latest international case studies and developments in concrete marine structures research, design, construction, and in-service experience.
