WATCH: Woodside removes Nganhurra RTM

Woodside removes Nganhurra RTM

Woodside Energy has safely removed the decommissioned Nganhurra Riser Turret Mooring (RTM), located approximately 38km north of the North West Cape in Western Australia (WA).

The company used heavy lift vessel Heerema Aegir, operated by Heerema Marine Contractors, to lift the 2500t RTM onto a 120m barge for transport to the Australian Marine Complex.

Once it is unloaded, the Nganhurra RTM will be cleaned and then deconstructed for recycling and reuse opportunities. More than 95 per cent of the Nganhurra RTM will be recycled or reused.

Woodside said the removal was a significant milestone for the company.

“This is a significant milestone for Woodside, further demonstrating our ability to manage activities in the sensitive marine environments where we operate,” the company said on LinkedIn.

Woodside used the Nganhurra floating production, storage and offtake facility to flush, isolate and preserve RTM and the subsea infrastructure in 2018.

The company first advised that the Nganhurra operations cessation environment plan was revised and resubmitted on December 20, 2019, to address alternatives for the removal of the RTM from the field for onshore disposal.
