SapuraOMV Upstream Pty Ltd. plans geotechnical and geophysical surveys within Permit WA-412-P, Commonwealth waters, western Australia. The site survey location is 163 km north of Karratha in water depths of 147 m. The permit, in the North West Marine Region, represents a 4 km x 4 km area.
Geophysical survey will collect data for assessment of water depths, seabed topography, seabed conditions, and identification of seabed obstructions. It will be conducted with multi-beam echo sounder (MBES), side scan sonar (SSS), sub-bottom profiler (SBP), and magnetometer.
Geotechnical survey is to assess and characterize seabed conditions within the operational area, including calibrating and interpreting geophysical results that may include cone penetration testing (CPT), piston coring or vibracore sampling, and box core sampling.
The survey is expected to occur between January and November for a duration of up to 14 days. Timing is dependent upon vessel availability, weather conditions, and receipt of required statutory approvals.
