Abstract:
The Hebron offshore oil development project comprises a reinforced concrete gravity-based structure (GBS), topsides structure, and offshore oil loading system and is being installed close to the existing Terra Nova, White Rose, and Hibernia platforms. Construction of the GBS is expected to be completed in 2016. The article summarizes the analysis and design of this complex structure as well as the materials, methods, and sequencing required to construct it.
