Project Profile
Value: US$2 billion
Location: Mississippi Canyon 254, Gulf of Mexico, USA
Start-up Year: 2015
Capacity: 80 MBOPD, 200 MMCFD, and 40 MBWPD
Water Depth: 1,890m – 6,237ft
Delta House will include a floating production system (FPS), an oil export line, a gas export line and a number of subsea systems. The Delta House FPS will be located in Mississippi Canyon 254 and is designed to accommodate production from a number of nearby fields, including LLOG’s previously announced discoveries in Mississippi Canyon 300 and Mississippi Canyon 431. The oil and gas export lines will connect the FPS to existing downstream pipeline infrastructure. The FPS will have capacity of 80 MBOPD, 200 MMCFD, and 40 MBWPD and space for 20 risers, which will allow production from up to nine simultaneously producing fields with dual flowlines. The FPS will have peaking capability up to 100 MBOPD and 240 MMCFD. The Facilities are expected to process and transport production from six initial wells when they begin commercial operation in 2015. Total capital required for the Project is over US$2B. The Delta House FPS will use the OPTI-11000® semi-submersible hull design developed by Exmar Offshore Company. In 2016, the Delta House floating production system achieved its nameplate oil capacity of 80,000. The FPS uptime has averaged in excess of 99% since production was initiated which we believe is best in class for similarly sized facilities.

Sub-contractors:
Ocean Installer: Contract for an umbilical installation project with Oceaneering for LLOG on the Delta House project. The scope of work includes umbilical transpooling, pre-lay survey, installation of umbilical with dynamic and static sections and umbilical pull-in to the semisubmersible. Normand Vision will use the 1800te carousel on the back deck of the vessel to install the umbilical for the Son of Bluto 2 discovery in approximately 2000m water depth. The offshore installation will start approximately on January 15, 2015. The project management and engineering is located in Ocean Installer’s Houston Office.
