NORBIT WINGHEAD i77h: Ultra-High-Resolution Multibeam Sonar

The NORBIT WINGHEAD i77h multibeam sonar delivers precise bathymetric surveys for pipeline inspections, coastal mapping, and USV operations worldwide.

NORBIT WINGHEAD i77h is a compact, ultra-high-resolution multibeam sonar system designed for detailed underwater mapping and inspection tasks. This curved array sonar excels in bathymetric surveys, construction monitoring, and operations with uncrewed surface vehicles (USVs), providing reliable data in challenging shallow water environments.

Manufactured by NORBIT Subsea, a division of the Norwegian technology firm NORBIT, the WINGHEAD i77h stands out for its lightweight and portable design, enabling rapid deployment on small vessels or USVs. Its cylindrical array technology captures high-resolution imagery, backscatter, and roll-stabilized bathymetry, making it essential for professionals in marine surveying, offshore infrastructure maintenance, and environmental monitoring.

What Makes NORBIT WINGHEAD i77h Unique

The core strength of the NORBIT WINGHEAD i77h lies in its advanced beamforming capabilities. It employs a true 1024-beam beamformer with a narrow 0.5 × 0.9-degree beam width, delivering exceptional resolution for detecting small features on the seabed. This precision is critical for applications requiring fine detail, such as identifying pipeline defects or mapping riverbeds.

Integrated GNSS/INS positioning and real-time sound velocity measurement ensure accurate georeferencing and depth calculations, even in dynamic conditions. The system's acoustic robustness handles noisy environments, maintaining data quality during operations near structures or in currents.

A dedicated pipeline mode optimizes performance for cable and pipeline inspections, adjusting beam patterns to focus on elongated targets. This feature reduces survey time and improves safety by minimizing the need for close approaches to hazards.

Key Applications of NORBIT WINGHEAD i77h

In shallow water bathymetry, the WINGHEAD i77h maps harbors, lakes, ponds, rivers, and estuaries with high fidelity. Its compact size suits small-boat operations, where larger sonars struggle with maneuverability.

For infrastructure inspections, it supports quay walls, bridges, and underwater structures, providing backscatter data that reveals material conditions and anomalies. Coastal surveys benefit from its ability to generate detailed topography for erosion studies or development planning.

The sonar's compatibility with USVs and UUVs extends its reach to remote or hazardous areas, supporting autonomous missions in offshore energy, aquaculture, and defense sectors.

Technical Specifications and Performance

Beam Configuration and Resolution

The NORBIT WINGHEAD i77h features a curved array with 1024 beams, achieving equiangular coverage across a wide swath. The 0.5-degree along-track by 0.9-degree across-track beam width enables sub-meter resolution at typical survey depths, surpassing many competitors in shallow waters.

Processing and Outputs

Built on a modern analog-digital platform, it processes data in real-time, outputting cleaned bathymetry, water column imagery, and amplitude data. Roll stabilization compensates for vessel motion, ensuring consistent nadir coverage.

Deployment Flexibility

Weighing under 10 kg and with a small footprint, the system mounts easily on pole systems or hulls. It operates at frequencies optimized for shallow to mid-water depths, typically 20 kHz to 1 MHz bands, though exact frequencies are tuned for specific models.

This portability drives adoption in regions with limited infrastructure, from European ports to Asian coastal projects and North American inland waterways.

Market Relevance for Marine Surveying

The global demand for high-resolution sonar stems from expanding offshore wind farms, subsea cable networks, and port modernizations. The NORBIT WINGHEAD i77h addresses needs in these sectors by enabling cost-effective surveys without large vessels.

In pipeline and cable inspection, regulatory mandates for integrity checks fuel growth. The sonar's pipeline mode aligns with industry standards from bodies like DNV and API, supporting compliance worldwide.

Competition includes systems from Teledyne RESON and R2Sonic, but NORBIT's focus on compact, high-channel count arrays gives it an edge in USV integration and shallow-water performance.

Integration with Modern Survey Workflows

The WINGHEAD i77h interfaces with popular software like QPS Qimera and EIVA NaviSuite, streamlining data processing. Its outputs support S-57 and IHO standards, facilitating delivery to clients in hydrographic offices and engineering firms.

For USV operations, low power consumption and Ethernet connectivity enable seamless integration with platforms like Ocean Science Technology's survey vessels.

Consumer and Industrial Impact

While primarily industrial, the sonar indirectly benefits consumers through safer infrastructure. Accurate seabed maps inform coastal development, reducing flood risks and supporting renewable energy that lowers electricity costs globally.

In aquaculture, it monitors net pens and seafloor conditions, enhancing sustainable fish farming practices amid rising seafood demand.

Supply Chain and Availability

NORBIT manufactures in Norway and China, leveraging vertical integration for transducers and electronics. Global distribution ensures availability for projects in Europe, North America, Asia-Pacific, and beyond.

Regulatory and Standards Compliance

The system meets IHO Special Order standards for bathymetry accuracy, vital for nautical charting. Its design complies with environmental regs for low acoustic impact on marine life.

Advancements in Sonar Technology

As the first cylindrical ultra-high-res curved array, the WINGHEAD series pioneered wide-swath coverage without gaps. Ongoing updates enhance signal processing for even cleaner data.

Case Studies and Real-World Use

Deployed in harbor dredging projects, it detects spoil mounds with centimeter precision. In river surveys, it maps sediment transport for flood management.

USV missions have mapped coastal zones post-storms, aiding rapid response.

Future Outlook for High-Resolution Sonar

Growing autonomous operations and 5G-enabled remote control will boost demand for compact sonars like the WINGHEAD i77h. Integration with AI for anomaly detection promises further efficiencies.
