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, enabling reliable data in challenging underwater environments worldwide.

The **NORBIT WINGHEAD i77h** is a compact, ultra-high-resolution multibeam sonar system designed for advanced underwater surveying. This curved array sonar excels in bathymetric mapping, infrastructure inspections, and operations with uncrewed surface vehicles (USVs), providing surveyors with detailed, accurate data across diverse aquatic environments.

Developed by NORBIT Subsea, the WINGHEAD i77h stands out for its lightweight and portable design, facilitating rapid deployment in shallow waters, rivers, harbors, and coastal zones. Its true 1024-beam beamformer and 0.5 × 0.9-degree beam width deliver exceptional resolution, making it ideal for detecting fine details in complex underwater terrains.

What is the NORBIT WINGHEAD i77h Multibeam Sonar?

The WINGHEAD i77h is part of NORBIT's pioneering WINGHEAD series, recognized as the first cylindrical ultra-high-resolution curved array bathymetric system. It integrates modern analog and digital platforms with advanced signal processing to produce roll-stabilized bathymetry, high-quality imagery, and backscatter outputs. This combination ensures consistent performance even in dynamic conditions, such as those encountered during vessel movements or rough seas.

Key technical features include integrated GNSS/INS for precise positioning and real-time sound velocity measurement for accurate depth calculations. These elements contribute to its industry-leading acoustic robustness, minimizing data errors in variable water conditions.

The system's compact form factor—lightweight and easy to transport—supports quick mobilization, which is crucial for time-sensitive survey projects. Operators appreciate its plug-and-play compatibility with various survey vessels and autonomous platforms.

Core Functions and Capabilities

At its core, the WINGHEAD i77h functions as a multibeam echo sounder, emitting acoustic pulses to map the seafloor and underwater structures. The curved array design provides wide swath coverage with high along-track resolution, capturing data over large areas efficiently.

A dedicated pipeline mode optimizes beamforming for inspecting underwater pipelines and cables. This mode enhances detection of anomalies like corrosion, leaks, or encroachments, which are critical for maintaining energy infrastructure integrity.

For general bathymetry, it supports shallow water operations down to pond and river levels, extending to coastal and harbor surveys. The system's high-resolution imagery aids in visualizing seabed textures, sediment types, and submerged obstacles.

Beamforming and Resolution Excellence

The 1024-beam true beamformer processes signals individually, avoiding interpolation artifacts common in lower-end systems. With a beam width of 0.5 degrees across-track and 0.9 degrees along-track, it achieves sub-meter resolution suitable for detailed engineering surveys.

Positioning and Environmental Adaptation

Built-in GNSS/INS fusion ensures georeferenced data accuracy within centimeters. Real-time sound velocity profiling corrects for water column variations, vital in stratified or temperature-gradient environments.

Primary Use Cases for the WINGHEAD i77h

The WINGHEAD i77h serves a broad spectrum of applications in marine surveying and engineering. Its versatility makes it indispensable for both routine monitoring and complex inspections.

• Shallow water bathymetry for dredging planning and volume calculations.
• Pipeline and cable route surveys to verify alignment and detect threats.
• Quay wall, bridge pier, and structure inspections for maintenance and safety assessments.
• Pond, river, and estuary mapping for environmental monitoring and flood risk analysis.
• Harbor and lake surveys for navigation channel maintenance.
• USV and UUV operations, leveraging its compact size for autonomous missions.
• Coastal surveys for erosion studies and shoreline management.

In pipeline inspections, the dedicated mode allows operators to follow linear assets precisely, generating 3D models that reveal burial depth, spanning, and free-spans. This data informs preventive maintenance, reducing downtime and environmental risks.

For USV integration, the sonar's low power draw and small footprint enable long-endurance surveys without manned vessels, enhancing safety and cost-efficiency in remote or hazardous areas.

Why the WINGHEAD i77h Matters for Industry

In the global hydrographic survey market, high-resolution sonar like the WINGHEAD i77h addresses growing demands for precision in offshore energy, port infrastructure, and environmental management. As underwater infrastructure expands—think subsea cables for renewable energy and telecom—the need for reliable inspection tools intensifies.

Marine contractors rely on such systems to meet stringent data quality standards set by bodies like the International Hydrographic Organization (IHO). The i77h's outputs comply with these, supporting Special Order surveys that require native resolution without averaging.

Its role in USV/UUV operations aligns with the shift toward autonomous surveying, driven by labor shortages and safety regulations. This positions it as a key enabler in digitalizing marine data collection worldwide.

Environmentally, accurate bathymetry aids in habitat mapping and impact assessments, helping regulators and developers balance development with conservation. In regions like Europe, Asia-Pacific, and North America, where coastal development booms, such tools are commercially vital.

Technical Specifications and Performance

The WINGHEAD i77h operates at frequencies optimized for shallow to medium depths, typically in the 300-700 kHz range for high-resolution imaging. While exact frequencies may vary by configuration, its design emphasizes broadband capabilities for multi-purpose use.

Swath coverage can extend up to 140 degrees, depending on water depth and settings, allowing efficient area coverage. Data processing occurs in real-time via NORBIT's software suite, which includes tools for cleaning, visualization, and export to standard formats like QINSy or Hypack.

Power requirements are modest, supporting battery-powered USVs, with ruggedized housing for harsh marine conditions (IP67 or equivalent). Weight under 10 kg enhances portability for field teams.

Acoustic Robustness Advantages

Advanced signal processing mitigates multipath interference and reverberation, common in cluttered environments like harbors with quay walls. This results in cleaner nadir beams and reliable outer beams.

Market Relevance and Commercial Role

The global multibeam sonar market is expanding due to investments in offshore wind, oil & gas decommissioning, and port expansions. Systems like the WINGHEAD i77h cater to mid-tier surveyors seeking premium performance without the bulk of ship-mounted sonars.

Competition includes offerings from Teledyne RESON, R2Sonic, and Kongsberg, but NORBIT differentiates with compact, high-res USV-focused designs. Demand is strong in Europe (NORBIT's home base), the US, and Asia, where USV adoption surges.

Supply chains for sonar components rely on precision electronics and transducers, with manufacturing centered in Norway for NORBIT products. Regulatory compliance with export controls and maritime standards ensures global availability.

Adoption patterns show increasing use in renewable energy surveys, such as cable routing for offshore wind farms, where high-resolution data reduces installation risks and costs.

Consumer and Operator Perspectives

While primarily an industrial tool, the WINGHEAD i77h benefits end-users like marine engineers and survey firms through enhanced productivity. Operators value its user-friendly interface and minimal setup time, reducing project turnaround.

For smaller firms or academic researchers, its affordability relative to larger systems democratizes access to IHO-compliant data, fostering innovation in coastal science.

Integration with Modern Survey Workflows

The sonar interfaces seamlessly with top-side software for live data visualization and post-processing. Outputs include point clouds, raster grids, and water column data, versatile for GIS and engineering analysis.

In USV setups, it pairs with autopilot systems for repeat surveys, enabling change detection over time—crucial for monitoring erosion or sediment transport.

Challenges and Limitations

Like all multibeam sonars, performance depends on water clarity and depth; it's optimized for shallow waters (up to 100m typically). Users must account for sound velocity profiles in deeper or variable conditions.

Maintenance involves periodic calibration, but its robust build minimizes downtime.
