A stabilizing design Audubon Companies' Denis Taylor and LLOG Exploration's Craig Mullett discuss changing design considerations for condensate stabilization on the Delta House FPS in the Gulf of Mexico. C oping with unexpected engineering challenges during the design and development of infrastructure is some- thing that is inherent in the deepwater offshore oil and gas industry. Case in point: LLOG Exploration's Delta House floating pro- duction system (FPS) in the Gulf of Mexico (GoM). Delta House, in Mississippi Canyon Block 254, was built under a rather unique set of circumstances. Unlike the conventional approach taken by most offshore operators, which involves delin- eating wells and studying reservoir composition before detailed design and construction begins, work on Delta House started before a discovery was even made. Part of this was due to the fact that the 20 or so deepwater leases acquired for production by LLOG in 2010 were set to expire in early 2014 – requiring expe- dition of the entire construction process so that the FPS could be brought online and wells could be drilled within 36 months.
