Prudhoe Bay Operations Center
Architects Alaska’s seminal Arctic endeavor was the Prudhoe Bay Operations Center (PBOC) for ARCO, designed in the 1970s. The team adopted a large sea-lift module approach to minimize both budget and disruption to ongoing site operations. These modules, set on simple field connections called “sponsons,” elevated the structure, reducing the impacts on sensitive permafrost and mitigating snowdrift accumulation.
The PBOC is a collection of four two-story residential modules branching out from a central unit. This core serves as an interactive hub, connecting the other modules. Unlike traditional designs, which were built on trestles or skids and needed removal, the PBOC modules were constructed in elevated positions for easy transport and installation. This resulted in swift turnaround times for the equipment and vessels involved, enhancing project efficiency.
