Description

SapuraOMV Upstream (Western Australia) Pty Ltd (SapuraOMV) plans to conduct a geotechnical and geophysical survey within Permit WA-412-P located in Commonwealth waters. The site survey location is approximately 163 km north of the town of Karratha in water depths of approximately 147 m. An Operational Area has been defined within Permit WA-412-P, which represents a 4 km x 4 km area encapsulating all potential geophysical and geotechnical survey locations.

The geophysical component of the survey will collect data for assessment of water depths, seabed topography, seabed conditions and identification of obstructions on the seabed that may include data collection with a multi-beam echo sounder (MBES), side scan sonar (SSS), sub-bottom profiler (SBP) and magnetometer.

The geotechnical component of the survey is to assess and characterise 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 has been planned to occur between January-November 2020 for a duration of up to 14 days.

The timing of the Survey is dependent upon vessel availability, weather conditions, the receipt of the required statutory approvals. Note the stipulated durations do not however, provide for vessel transit times, potential delays caused by ocean conditions, weather downtime, standby and equipment failure or other delays relative to the survey plan, as these factors are difficult to predict or quantify. Survey activities will be undertaken 24 hours per day.
