Abstract: The economic development of offshore Arctic petroleum fields dictates that Arctic structures be both cost-effective and deliverable with minimum lead time. Concrete structures are typically highly reinforced, and liberal application of multiaxial prestressing is common. Without substantial thought given to the construction process during the design phase of a project, these complex structures can be difficult and costly to build. The authors have experience in the design and implementation of many cost-effective structural concepts that can be used for these unique structures. Selection of materials, choice of internal framing systems, and attention to detail at connections are just some of the methods by which complex concrete Arctic structures can be efficiently constructed. A design philosophy is outlined which can be used to develop highly efficient, uncomplicated structural concepts. Examples of actual applications are presented along with the rationale for their development.
