Case Study: Delta House O ffshore production presents some of the most difficult logistical, technological, and financial challenges facing the oil and gas industry today. In an effort to access deepwater reserves in fields that were at one time considered inaccessible, operators throughout the globe have to design and build floating production systems (FPS) that test the bounds of engineering and construction. Even more challenging is the fact that companies are being asked to do this on increasingly aggressive project schedules; and with the Delta House FPS in the Gulf of Mexico (GOM), this was exactly the case. Project Background The Delta House facility is a floating production system installed at a water depth of 4,500 feet approximately 130 miles southeast of New Orleans. It is part of the Delta House Field Development Project -- a joint venture between LLOG Exploration Co., LLC and Blackstone Energy Partners (and its affiliates) that will involve the drilling of 15 wells (six of which are already complete) in the Mississippi Canyon Block 254 over the next two years. Initial Situation The Delta House project was officially approved in December 2012, allowing the construction on the FPS to begin. The initial goal was to have the offshore facility fabricated and installed within 30 months – a rather aggressive timeline when compared to similar platforms in operation throughout the GOM. In addition to making Delta House extremely challenging from a scheduling standpoint, the involvement of several separate contractors providing services, ranging from regulatory oversight and construction management to engineering design and lifting, made for a highly complex commissioning process. Key contractors that worked on Delta House included EXMAR Offshore Company, the hull design company; Kiewit Offshore Services (KOS), the topsides integration and lift contractor; and Pinnacle Engineering, the subsea engineering company. Audubon Companies was selected by LLOG for multiple project roles. Audubon Engineering Solutions was chosen as the topsides engineering contractor and Audubon Field Solutions as a liaison between engineering and construction. While the initial scope of work for Audubon Field Solutions was relatively minor, it became clear in the early stages of the construction process that the high number of contractors coupled with a tight timeline would require extensive collaboration and coordination between parties in order for the project to remain on schedule. As a result, the Audubon Field Solutions' scope of work was expanded to include interface management services, a role that would eventually prove critical to the overall success of the Delta House project. Expanded Interface Management Role Results in Successful 30 Month Sanction-to-Installation Schedule
