The project involves the development of a mixed-use waterfront community and urban regeneration on the former main port of Sultanate of Oman. The site, approximately 114 hectares, is located in Muttrah, adjacent to the historic district and fronting the Corniche. It has a potential Gross Floor Area (GFA) ranging from 700,000 m² to 800,000 m². The client requires hydrographic and dive inspection survey data for berths 1 to 10 at the Port Sultan Qaboos Development Project, Muscat. This data is essential for assessing the seabed layout, quay wall condition, and foundation at the berth sites.

Scope of the Survey

The survey focused on the quay wall, employing advanced techniques to obtain accurate and detailed information about the site.

Equipments of the Study

• M3 Multibeam Sonar Hydrographic System
• TSS DMS 3-05 Dynamic Motion Sensor
• Sound Velocity Probe – AML SV Probe
• Sound Velocity Profiler – AML SV Profiler
• Data Acquisition & Processing Software: Hypack & Hysweep Software
• Tide Recorder – Valeport Tide Master

Bathymetry Survey Procedure

A pre-survey investigation was conducted to ensure site safety and to meet the client’s survey objectives within the defined survey areas. The following procedures were followed:

• Installed a Valeport tide gauge for tide correction.
• Mounted the GPS antenna at the top of and in the same vertical plane as the M3 Sonar Pole for accurate horizontal positioning of the transducer.
• Logged M3 Multibeam Sonar data using the navigation computer. Conducted CTDS dips and bar checks each day before starting the survey. Entered draft and mean sound speed values directly into Hysweep software.
• Utilized the TSS Motion Sensor for Heave, Pitch, and Roll corrections.
• Ensured phase and speed settings for unobstructed records. Connected the Hemisphere DGPS for Heading. The Leica RTK system included a computer loaded with Hysweep software for GPS positioning. The computer received corrected GPS-derived Latitude and Longitude, and Hysweep software converted the antenna position into local UTM projection coordinates.
