DESIGN AND FABRICATION OF THE AUGER DECK

The Auger deck structure, covering an area approximately 300 feet by 300 feet, is an open truss design that provides support for nine major modules and numerous equipment skids that are required for drilling and production operations. The design of the deck was accomplished in four distinct cycles that increased in sophistication as the design requirements matured. The concept cycle allowed for the efficient evaluation of major system configuration alternatives. The preliminary cycle provided realistic weight estimates of alternative truss configurations in the deck. Once the final configuration was set, the design and analysis cycle was utilized to develop construction drawings. The final cycle was during the early construction phase to adapt the design to the contractors capabilities and fabrication plants. The primary trusses, assembled from prefabricated nodes and girders, along with other prefabricated subcomponents, were constructed in buildings, transported to the erection site and assembled to form the complete deck. Major modules and other equipment skids were integrated into the structure as the structural components were erected.
