Deepwater floating production facility projects are expensive to initiate and can carry a substantial amount of risk. The topsides production facilities are perhaps the most critical facet of any project. It is this area Wood has proven its leadership, with responsibility for more than half of topsides facilities in the US Gulf of Mexico (GOM).

Wood has built a solid relationship with Anadarko Petroleum, assisting them in engineering six previous floating production facilities, including the industry’s first identical spars, Boomvang and Nansen. For those projects, Wood successfully duplicated much of its front-end engineering design (FEED) and detailed design packages, greatly improving procurement and fabrication schedules.

Lessons learned and efficiencies demonstrated on Boomvang and Nansen were duplicated by Wood on Anadarko’s newest GOM facilities, Lucius and Heidelberg. During the construction of Lucius, it became apparent that Heidelberg, despite different water depths, had comparable 80,000 bpd/oil planned throughput. The ‘Design One, Build Two’ approach provided flexibility for expansion of both facilities. While Lucius was progressing, common design package elements reduced Heidelberg pre-FEED and FEED manhours by 60% and were largely responsible for advancing sanction (FID) for both projects. Heidelberg topsides steel was confidently cut one month following sanction. Equipment was standardized and several production components were modularized.

The Heidelberg topsides end results showed a 22% reduction in fabrication manhours, 33% lowering of engineering manhours and 50% improvement in equipment procurement cycle. It is another example of Wood’s cost saving capability for deepwater clients on their world-class topsides projects.
