Project Synopsis: Port Sultan Qaboos Development Project - Quay Wall and Berth Survey

Customer: DAMAC

The project involves the urban renewal and creation of a mixed-use waterfront town on the site of the former main port of the Sultanate of Oman. Covering over 114 hectares, this property is strategically located in Muttrah, overlooking the Corniche and in close proximity to the historic quarter. With a potential Gross Floor Area (GFA) ranging between 700,000 and 800,000 square meters, the development is a significant undertaking. The client required detailed data from diving inspections and hydrographic surveys for berths 1 through 10 at the Port Sultan Qaboos Development Project in Muscat. This data is essential for assessing the condition of the quay wall, the seabed topography, and the foundation at the berth locations.

The Survey's Scope: The primary focus of the survey was the quay wall, employing advanced techniques to collect accurate and comprehensive data of the site.

Survey Equipment:

• TSS DMS 3-05 M3 Multibeam Sonar
• Hydrographic System Sound Velocity Probe - AML SV Probe
• Dynamic Motion Sensor
• Sound Velocity Profiler - AML SV Profiler

Data Collection and Processing Software: Hypack & Hysweep Software

Bathymetry Survey Procedure: The survey followed a carefully planned procedure using the Valeport Tide Master Tide Recorder to ensure accurate and reliable results.

• A pre-survey study was conducted within the designated survey areas to meet the client's objectives and ensure site safety.
• A Valeport tide gauge was installed for tide correction.
• The GPS antenna was mounted atop the M3 Sonar Pole in the same vertical plane to ensure precise horizontal alignment of the transducer.
• Data was logged using the M3 Multibeam Sonar's navigation computer.
• Bar checks and CTD dips were performed daily before commencing the survey to ensure data accuracy.
• Mean sound speed and draft values were directly input into the Hysweep software.
• Heave, pitch, and roll adjustments were made using the TSS Motion Sensor to correct for vessel movement.
• Phase and speed settings were calibrated to ensure clear data recordings.
• Heading was determined using Hemisphere DGPS.
• GPS position was calculated using a Leica RTK system, and corrected latitude and longitude coordinates were converted into local UTM projection using Hysweep software.

Conclusion: The survey of berths 1 through 10 at the Port Sultan Qaboos Development Project provided critical insights into the condition of the quay wall and seabed, supporting the client in their assessment and future planning for the mixed-use waterfront town development.
