Ms Leonie Chapman
Carnarvon Hibiscus Pty Ltd (‘CHPL’) is proposing to undertake a Geotechnical and Geophysical Survey in the Commonwealth waters of the Gippsland Basin to support site selection for the West Seahorse (WSH) Development infrastructure and site selection for an exploration target, Sea Lion. The WSH Field is located in Production Licence VIC/L31 in Bass Strait and Sea Lion is located in the south‐west section of exploration permit VIC/P57. The WSH Field is located approximately 18km SSE of Loch Sport, with the closest landfall site 14km north‐west on the Ninety Beach at a point midway between Loch Sport and Golden Beach. Sea Lion is located approximately 6.5km inshore from the WSH location and is located approximately 13.5km SSW of Loch Sport.
The purpose of the survey is to:
• Obtain information on the seabed conditions at the WSH location for the proposed development infrastructure (Mobile Offshore Production Unit [MOPU], export crude flowline and Floating Storage and Offloading [FSO] Vessel);
• Geotechnical information for the infrastructure for MOPU foundations and anchoring of the FSO’s Rigid Arm and information associated with the flowline corridor between Sea Lion and WSH should the Sea Lion well be successful; and
• Obtain information on the seabed conditions at the Sea Lion location for the West Telesto Jack‐up rig during exploration drilling activities.
The surveys will have a combined duration of approximately 13 days, and will operate on a 24hr/7 day basis. They will be conducted between 2015 and 2016.
