Project summary

Audubon provided topsides engineering and modifications for Williams’ proposed Gulfstar FPS, a spar-based floating production system. The scope of work included conceptual design, front-end engineering design (FEED), and project management. The structure is a classic spar hull with traditional three-level topsides. The design is based on the Gulfstar One, the first spar-based FPS with major components built in the U.S.
