Activity description

A revision of the Environment Plan has been submitted for activities to occur in 2019.

Quadrant Oil Australia Pty Ltd (QOA) is the registered operator for Petroleum Production Licence WA-13-L in offshore Commonwealth waters on the North West Shelf (NWS) of Western Australia (WA). QOA is 100% owned subsidiary of Quadrant Energy Australia Ltd (Quadrant). Quadrant proposes to install infrastructure required to perform intelligent pigging (inspection) activities of the East Spar system, and remove flowlines and associated infrastructure which are at the end of design life and no longer used in production.

 The East Spar Inspection and Removal activities will be carried out using a Dive Support Vessel (DSV) or Installation Support Vessel (ISV).  Installation of infrastructure is required to allow intelligent pigging activities to inspect the East Spar system, prior to removal of flowlines and associated infrastructure of the East Spar 1, 3 and 6 Production System.
