Longhorn/Appaloosa Facilities

Eni Longhorn

Audubon Companies’ scope of work for the Longhorn/Appaloosa facilities project included engineering and design, project management, procurement, automation, equipment inspection and construction management. Structural analysis was performed to verify the platform’s sustainability for the intended field development. Additional work included the interface between topsides and subsea wells, including support for HPU and TUTA and automation links between the topsides and subsea controls programming. Our team also provided the decommissioning of the existing production module and construction management for onshore and offshore activities.
