The Ngujima-Yin facility comprises the Ngujima-Yin offshore floating production, storage and offloading (FPSO) vessel and associated subsea infrastructure. 
The facility currently produces crude oil from the Vincent area reservoir located in Production Licence WA-28-L. With the addition of the Greater Enfield Project, a 12 well subsea tieback to the Ngujima-Yin FPSO, the facility will also produce from hydrocarbon reserves in WA-59-L, and will include the operation of a licenced pipeline (WA-28-PL) tied back to the FPSO.
The facility’s current operations EP was accepted by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) in 2014.
Woodside is submitting a revised Environment Plan for the Ngujima-Yin Facility operations in accordance with the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009 (Cth) (the regulations).  The Environment Plan (EP) is being revised to account for the commissioning and operation of the Greater Enfield Project. In addition this revision also incorporates a five yearly update to the existing EP as required by the regulations.
