Project summary

Audubon simultaneously executed the Blue Wing Olive and Red Zinger subsea tiebacks to LLOG’s Delta House, resulting in greater engineering and construction efficiencies. Our scope of work included multidisciplinary engineering and design for the platform’s topsides modifications, procurement, and construction planning and management. The topsides drafting and design team utilized PDMS software for all design work.
