Activity description

The Cobia Pipeline Repair Project Environment Plan covers the repair of the existing 300mm pipeline between the Halibut and Cobia Platforms located in Production Area VIC/L05 in Bass Strait. The repair involves the Seven Eagle dive support vessel laying a 150mm flexible pipeline between the Halibut and Cobia risers and making the associated tie-ins. The campaign is expected to take place in December 2018 and last approximately 10 days and will involve divers and ROV activities. 

The Environment Plan also covers leaving the redundant CBA300 pipeline in-situ until future decommissioning plans are developed or the pipeline is incorporated into a new or revised operations Environment Plan. Until decommissioning is completed, maintenance activities on the pipeline will continue be undertaken. The Cobia Pipeline Repair Project Environment Plan will cease when the new or revised operations Environment Plan is accepted by NOPSEMA.
