Hartshead Resources NL has announced that the Company is mobilising for the Geotechnical Survey across the Anning and Somerville fields and pipeline locations using Geoquip Marine Operations (Geoquip Marine).
The Geoquip Seehorn, an 83 metre Class 2 Dynamic Positioning (DP2) Multi-Disciplined Offshore Survey Vessel, with specialist deep seabed testing and borehole testing capability, will be used for the work program.
The main objectives of the geotechnical survey are to provide the Company with confirmation of the seabed and sub seabed soil conditions to finalize the design and the efficient installation of the offshore facilities and to ensure the safe location of the jack-up drilling rig at the Anning and Somerville locations.
The survey will consist of the following components:
• One 50m borehole at the jacket centres and one 30m borehole at each jack-up location leg centroid, boreholes will be advanced with a combination ofsamples and CPTs,
• Onshore / offshore laboratory testing, which shall be performed in accordance with internationalstandards and procedures (i.e. ISO, ASTM, BSI, NS, ISRM, or equivalent).
Chris Lewis, Hartshead CEO, commented “We are rapidly progressing our Phase I development with work across platforms, pipelines, wells and offtake advancing well. With the recent submission of our Field Development Plan we will now move to progress our Environmental Statement later this year. The Company is very focused on delivering the key milestone of taking FID on Phase 1, later this year.
