Woodside is seeking environmental approval to undertake petroleum activities to support the cessation of operations from the Balnaves oil field. The Balnaves infrastructure is located in production licence WA-49-L in Commonwealth waters. The Balnaves oil field is about 48 km north-west of the Montebello Islands and 75 km north-west of Varanus Island. Water depths over the field vary from 110 m to 160 m.
Activities are anticipated to be undertaken within a 6-12 month timeframe and in two phases (this Environment Plan being the first phase).
ACTIVITY SUMMARY
Activities to be undertaken in this phase include:
Ongoing preservation of the Balnaves subsea systems and riser turret mooring (RTM) (also known as disconnectable turret mooring) until RTM removal.
Vessel monitoring, including subsea inspections by remotely operated vehicle of the Balnaves field and RTM.
 
Further activities, including disconnection and removal of RTM, will be subject to future EP submissions
