NORBIT WINGHEAD i77h: Ultra-High-Resolution Multibeam Sonar

The NORBIT WINGHEAD i77h multibeam sonar delivers precise bathymetric surveys for pipeline inspections, USV operations, and coastal mapping, setting standards in compact, high-performance subsea technology worldwide.

NORBIT WINGHEAD i77h is a compact, ultra-high-resolution multibeam sonar system engineered for demanding bathymetric and inspection surveys. This curved array sonar excels in shallow water mapping, pipeline and cable inspections, and operations with uncrewed surface vehicles (USVs), providing surveyors with reliable, high-density data in challenging environments.

Designed by NORBIT Subsea, the WINGHEAD i77h stands out for its lightweight and portable build, enabling rapid deployment from small vessels or USVs. Its cylindrical array technology delivers roll-stabilized bathymetry, detailed imagery, and backscatter outputs, making it ideal for precision tasks in harbors, rivers, and coastal zones.

What is the NORBIT WINGHEAD i77h?

The **NORBIT WINGHEAD i77h** represents a breakthrough in multibeam sonar with a true 1024-beam beamformer and 0.5 × 0.9-degree beam width, ensuring ultra-high-resolution coverage. Built on a modern analog and digital platform, it incorporates advanced signal processing for consistent performance across varied conditions. Integrated GNSS/INS positioning and real-time sound velocity measurement enhance depth accuracy, critical for professional surveys.

This system is the first cylindrical ultra-high-resolution curved array bathymetric sonar in its series, optimized for mobility and efficiency. Its acoustic robustness handles noisy environments, while the dedicated pipeline mode fine-tunes it for underwater infrastructure inspections.

Key Technical Specifications

At the core of the WINGHEAD i77h is its curved array transducer, which provides wide swath coverage with minimal gaps. The 1024 beams enable dense point clouds for detailed 3D models, surpassing traditional flat-array sonars in resolution and uniformity. Operating frequencies and power adjustments support shallow to moderate depths, typically up to 100 meters depending on conditions, though exact ranges vary by application.

Power efficiency and low weight—under 10 kg for the head—facilitate integration with USVs, reducing operational costs for remote or autonomous surveys. Data processing occurs in real-time, compatible with industry-standard software like QINSy or Hypack.

Primary Functions and Capabilities

The WINGHEAD i77h performs high-resolution bathymetry, capturing seafloor topography with centimeter-level precision. It generates nadir bathymetry, sidescan-like imagery, and backscatter for material classification, aiding in habitat mapping and object detection.

In pipeline mode, it optimizes beam steering for elongated targets, improving detection of small defects or burial status. Roll stabilization compensates for vessel motion, ensuring data quality in rough seas.

Integration with Positioning Systems

Seamless GNSS/INS integration provides sub-decimeter positioning accuracy, essential for georeferenced surveys. Real-time sound velocity profiling corrects for water column variations, minimizing refraction errors in stratified waters.

Use Cases in Marine Surveys

NORBIT WINGHEAD i77h shines in shallow water bathymetry for port dredging, riverbed monitoring, and lake charting. Its compact size suits estuary and pond surveys where larger systems falter.

For infrastructure, it inspects quay walls, bridges, and subsea structures, identifying corrosion or scour. Pipeline and cable route surveys benefit from its high resolution, spotting hazards like free spans or debris.

In uncrewed operations, USVs and UUVs deploy the i77h for coastal erosion studies or offshore wind farm site assessments, extending reach without crew risk.

Why the WINGHEAD i77h Matters for Industry

In the global marine survey sector, the WINGHEAD i77h addresses demands for higher resolution from smaller platforms. As offshore energy, renewables, and port expansions grow, compact sonars like this reduce mobilization time and costs, boosting efficiency.

Its USV compatibility aligns with the shift to autonomous surveying, driven by labor shortages and safety priorities. High-resolution data supports regulatory compliance for environmental impact assessments and asset integrity.

For consumers indirectly, accurate surveys ensure safer navigation in busy harbors and reliable coastal infrastructure, underpinning tourism and fisheries.

Market Relevance and Demand Drivers

The multibeam sonar market expands with underwater infrastructure investments. Demand for systems like the WINGHEAD i77h rises in offshore wind, subsea cables for data centers, and pipeline maintenance amid energy transitions.

Competition includes Teledyne RESON and R2Sonic, but NORBIT's focus on compact, high-beam-count arrays differentiates it for USV-centric operations. Supply chains rely on precision manufacturing for transducers, with global adoption in Europe, Asia, and North America.

Technical Advantages Over Competitors

Unlike flat multibeam sonars, the curved array of the i77h maintains uniform resolution across the swath, reducing artifacts in oblique angles. The 1024 beams provide denser coverage than 400-512 beam systems, ideal for feature detection.

Pipeline mode employs proprietary beamforming for anisotropic targets, outperforming general-purpose sonars in linear inspections.

Operational Flexibility

Quick setup—under 30 minutes—and hot-swappable components minimize downtime. Waterproof ratings and corrosion-resistant materials suit harsh marine conditions.

Consumer and Industrial Applications Worldwide

Industrially, hydrographic offices use it for national charting updates. Oil & gas firms deploy for decommissioning surveys, while renewables scout turbine sites.

Consumer-facing roles include recreational harbor dredging and environmental NGOs mapping coral reefs. Globally, it's relevant from Baltic ports to Australian coasts.

Regulatory and Adoption Trends

Compliance with IHO standards for bathymetry ensures data usability for official charts. Adoption grows with USV regulations favoring low-signature sensors.

In supply chains, NORBIT sources components globally, mitigating disruptions through diversified manufacturing.
