Shelf Subsea have announced that the Southern Star, DPIII Saturation Diving Vessel, has arrived in New Zealand waters to commence work on phase 2 of the Tui decommissioning project.
The New Zealand Ministry of Business, Innovation and Employment (MBIE) awarded the contract to Shelf Subsea for the removal of the subsea infrastructure from the Tui Oil Field (phase 2 of the decommissioning process). This is the next step in the decommissioning of the field after the disconnection and demobilisation of the FPSO Umuroa was completed in May 2021.
The Southern Star, a 112m vessel with a 150t AHC crane, 1000m of back deck and installed WROVs. It arrived in New Zealand after encountering some poor weather, which was easily overcome.
Shelf Subsea noted that it is the most advanced DSV operating in the Asia Pacific region and comes with Port and Starboard SPHLs for greater driver safety and more efficient operations in blow-on, blow-off scenarios. As demonstrated on the journey over, the vessel handles exceptionally well in challenging weather conditions providing a stable platform for subsea intervention work.
