NORBIT WINGHEAD i77h Multibeam Sonar Explained

The NORBIT WINGHEAD i77h multibeam sonar delivers ultra-high-resolution underwater mapping for pipeline inspections, coastal surveys, and USV operations, enabling precise data in challenging environments worldwide.

NORBIT WINGHEAD i77h is a compact, ultra-high-resolution multibeam sonar system designed for detailed underwater surveys. This curved array sonar excels in bathymetric mapping, providing precise depth measurements and imagery for marine applications.

Developed by NORBIT Subsea, the WINGHEAD i77h features a 0.5 × 0.9-degree beam width, enabling exceptional resolution for small-scale features detection. Its true 1024 beams beamformer ensures accurate data across swaths up to 140 degrees.

The system's lightweight and portable design—under 10 kg—facilitates deployment from small vessels, uncrewed surface vehicles (USVs), or remotely operated vehicles (ROVs). Integrated GNSS/INS positioning and real-time sound velocity profiling deliver centimeter-level accuracy in dynamic conditions.

NORBIT WINGHEAD i77h Key Technical Features

The NORBIT WINGHEAD i77h operates on a modern analog-digital platform with advanced signal processing. Roll stabilization compensates for vessel motion, producing consistent bathymetry, high-quality imagery, and backscatter data.

Acoustic robustness allows reliable performance in noisy environments, such as near-shore areas with high reverberation. A dedicated pipeline mode optimizes beamforming for cable and pipeline route surveys, minimizing shadows and artifacts.

Frequency options include shallow-water modes around 300-400 kHz, balancing range and resolution. Outputs integrate seamlessly with survey software like QPS Qimera or Navlab Hypack for real-time processing.

Beamforming and Resolution Advantages

The cylindrical array design—first in its class for ultra-high resolution—curves the transducers to maintain uniform beam angles across the swath. This reduces nadir gaps and improves outer-beam quality compared to flat arrays.

Positioning and Calibration

Built-in GNSS/INS fusion with patch antennas ensures sub-decimeter positioning. Automated sound velocity correction via an integrated sensor profiles the water column, adapting to thermoclines and salinity gradients.

Primary Use Cases for WINGHEAD i77h

Shallow water bathymetry represents a core application, mapping harbors, rivers, and estuaries where traditional sonars struggle with resolution. The system charts bottom topography for dredging, navigation, and coastal management.

Pipeline and cable inspection surveys benefit from the optimized mode, detecting crossings, free spans, and burial depths. Operators use backscatter for material identification, aiding maintenance in oil & gas and telecom sectors.

Structure inspections cover quay walls, bridges, piers, and offshore platforms. High-resolution imagery reveals corrosion, scour, and debris without diver intervention.

USV and UUV Integration

Compact size suits uncrewed vehicles, enabling autonomous surveys in hazardous areas like polluted ponds or military zones. Low power draw—under 50W—supports extended missions.

Why NORBIT WINGHEAD i77h Matters for Industry

In marine surveying, precision drives efficiency. The WINGHEAD i77h reduces survey time by delivering survey-grade data from small platforms, lowering mobilization costs for contractors worldwide.

Global demand stems from offshore energy expansion, port infrastructure upgrades, and coastal resilience projects. Regulations like IMO standards for navigation safety mandate high-accuracy hydrographic data.

Competition includes Teledyne RESON and R2Sonic systems, but WINGHEAD i77h differentiates with its curved array and pipeline focus, appealing to niche inspection markets.

Supply chains rely on Norwegian manufacturing for transducers, with exports to Europe, North America, and Asia. Adoption grows in renewable sectors like offshore wind farm site assessments.

Consumer and Environmental Relevance

While primarily industrial, the sonar supports environmental monitoring. Estuary and lake surveys track sedimentation, aiding fisheries management and flood risk modeling for coastal communities.

Pond and river applications assist water resource agencies in volume calculations and invasive species detection, benefiting agriculture and recreation indirectly.

Coastal Survey Applications

High-resolution mapping informs erosion studies and beach nourishment projects, protecting billions in global coastal assets from climate impacts.

Operational Advantages in Challenging Environments

Harbor surveys navigate dense traffic and variable depths, providing clean data for berth design and sediment management. The system's multi-output—waterfall imagery, snippets, and point clouds—supports diverse analysis.

In estuaries, tidal currents and turbidity test acoustic performance; WINGHEAD i77h's processing mitigates multipath interference for reliable results.

Market Role and Commercial Significance

The multibeam sonar market, valued in billions, grows with autonomous vessels and subsea infrastructure. WINGHEAD i77h targets mid-tier operators seeking premium resolution without large-vessel requirements.

Its role expands in blue economy sectors: aquaculture site selection, seabed mining reconnaissance, and marine renewables. Versatility drives repeat purchases for survey firms serving EPC contractors.

Regulatory compliance—such as IHO S-44 standards for hydrography—elevates its value, as certified data reduces liability in engineering projects.

Integration and Workflow Efficiency

User-friendly topside software handles calibration, data cleaning, and export. Ethernet connectivity enables multi-sensor fusion with lidar, cameras, or profilers on USVs.

Quick mobilization—under an hour setup—suits time-sensitive inspections, contrasting bulkier competitors requiring cranes and gantries.

Advancements in Sonar Technology via WINGHEAD i77h

The curved array innovation sets a benchmark, influencing next-gen designs. Acoustic lens technology focuses beams without mechanical steering, enhancing swath coverage in shallow waters.

Future-proof firmware supports frequency agility, adapting to evolving survey needs like higher-resolution modes for AUVs.

Global Deployment Examples

European port authorities use it for annual quay inspections; Asian offshore operators map cable routes amid expanding 5G subsea networks. North American firms deploy on USVs for Great Lakes charting.

These cases highlight scalability from local rivers to EEZ boundaries.
