Woodside has been given the green light by the national offshore regulator to undertake decommissioning activities at the Greater Enfield Project in permit areas WA-28-L.
The company has been given approval to undertake the removal of infrastructure above the mudline including manifolds, flowlines, umbilicals, mooring chains, and spools.
As well as confirmation to leave in-situ of 10 anchors, each including a section of mooring chain which are completely buried below the seabed.
The proposed petroleum activities program is planned to occur between 2022 and 2024 and will take up to 12 months cumulatively.
Activities may occur during one or multiple campaigns. The potential for concurrent operations with other decommissioning activities is assessed and managed in the EP.
When ongoing, activities will be 24 hours per day, seven days per week. Timing and duration of these activities is subject to change due to project schedule requirements, vessel availability, unforeseen circumstances and weather.
