POA-2015-16

Expiration date: 9/20/2017

Ms. Kate Kaufman (Hilcorp Alaska, LLC) stated the purpose for the development is to recover oil from the Liberty Prospect and transport it to the Trans Alaska Pipeline System via the Badami Pipeline.

The project site is located within two federal leases (OCS-Y1650 and OCS-Y1585), in Foggy Island Bay within the Beaufort Sea, northeast of the Prudhoe Bay Unit, and east of the Duck Island Unit. The Liberty Development Production Island (LDPI) will be located approximately 5 miles north of the Kadleroshilik River in approximately 19 feet of waters at Latitude 70.2746º N., Longitude 147.5863º W.

Hilcorp Alaska, LLC (HAK) proposes to construct a self-contained offshore drilling and production facility located in the Beaufort Sea OCS. A 12-inch sales oil pipeline inside a 16-inch outer pipe will transport crude oil from the facility to the Badami Sales Oil Pipeline. The offshore portion of the pipeline will be trenched on the ocean floor. The overland portion of the pipeline will be trenched for 350 feet (ft) from the shoreline, and then elevated approximately 7 ft high on vertical support members (VSMs) for most of the remaining distance to the Badami tie-in. The onshore pipeline will go underneath a newly constructed gravel pad where it intersects with the Badami ice road. A second gravel pad will be constructed at the pipeline tie-in point with the Badami Pipeline. HAK also proposes to mine the gravel needed for the project from a selected nearby site. All work would be performed in accordance with the enclosed plan (sheets 1 – 23), dated 06/13/17.
