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, enabling accurate underwater data collection in challenging environments.

The **NORBIT WINGHEAD i77h** is a compact, ultra-high-resolution multibeam sonar system designed for advanced underwater surveying. Engineered by NORBIT Subsea, this curved array sonar excels in bathymetric surveys, pipeline and cable inspections, and operations with uncrewed surface vehicles (USVs). Its lightweight design facilitates easy deployment across diverse marine environments, from shallow waters to coastal zones.

At the core of the WINGHEAD i77h's capabilities is its true 1024-beam beamformer, which provides exceptional resolution with a 0.5 × 0.9-degree beam width. This allows for detailed mapping of underwater topography, structures, and features. The system's industry-leading acoustic robustness ensures reliable performance even in noisy or complex conditions, making it suitable for professional survey operations globally.

WINGHEAD i77h Key Technical Features

The sonar integrates GNSS/INS technology for precise positioning, combined with real-time sound velocity measurement to maintain depth accuracy. These features minimize errors in dynamic survey scenarios. A dedicated pipeline mode optimizes beamforming and processing specifically for inspecting underwater pipelines and cables, enhancing detection of anomalies like corrosion or damage.

Built on a modern analogue and digital platform, the WINGHEAD i77h supports roll-stabilized bathymetry, high-quality imagery, and backscatter outputs. This versatility outputs clean, georeferenced data ready for analysis in standard hydrographic software. The compact form factor—lightweight and portable—reduces mobilization time, ideal for rapid-response surveys or remote deployments.

Beamforming and Resolution Advantages

The 1024-beam configuration represents a leap in multibeam sonar technology, forming narrower beams across a wide swath. This results in higher point density for ultra-high-resolution datasets, crucial for applications requiring fine detail, such as bridge pier inspections or riverbed mapping. Compared to traditional flat-array sonars, the cylindrical curved array of the WINGHEAD series provides consistent performance across the full swath width.

Integrated Positioning and Environmental Compensation

Real-time sound velocity profiling corrects for water column variations, ensuring depth measurements remain accurate regardless of salinity, temperature, or depth changes. Coupled with roll stabilization, the system compensates for vessel motion, delivering stable data in rough seas or on small USVs.

Primary Use Cases for WINGHEAD i77h

In shallow water bathymetry, the i77h maps seabeds with centimeter-level precision, supporting dredging operations, port maintenance, and environmental monitoring. For pipeline and cable route surveys, the dedicated mode identifies burial depths, free spans, and encroachments, critical for offshore energy infrastructure integrity.

Quay wall, bridge, and structure inspections benefit from the sonar's high-resolution imagery, revealing defects invisible to divers or ROVs. Pond, river, and estuary surveys aid flood risk assessment and habitat restoration. Harbor and lake mapping ensures safe navigation by detecting wrecks or shoals. The system's USV/UUV compatibility extends its reach to autonomous operations in hazardous or inaccessible areas.

Coastal surveys leverage the i77h for shoreline erosion studies, beach nourishment projects, and marine spatial planning. These applications span commercial shipping, renewable energy, aquaculture, and defense sectors worldwide.

Why WINGHEAD i77h Matters for Industry

For marine surveyors and hydrographers, the i77h reduces operational costs through faster data acquisition and minimal setup. Its high data quality cuts post-processing time, accelerating project delivery. In industries like oil and gas, renewables, and construction, accurate underwater data informs billion-dollar decisions on asset placement and maintenance.

The shift toward uncrewed systems amplifies the i77h's relevance. Deployable on small USVs, it enables safe, efficient surveys over large areas without risking personnel. This aligns with global trends in automation and remote sensing, particularly in regions with challenging logistics like the Arctic or deep-water tropics.

Market Relevance and Global Demand

The global hydrographic survey market grows with rising offshore activities, including wind farms, subsea cables for data centers, and port expansions. Multibeam sonars like the i77h meet demand for higher resolution amid stricter environmental regulations requiring precise baseline data.

Competition includes systems from Teledyne RESON, Kongsberg, and R2Sonic, but the i77h stands out for its compact size and pipeline specialization. NORBIT's focus on integrated solutions positions it well in the USV ecosystem, where demand surges for low-SWaP (Size, Weight, and Power) sensors.

Supply Chain and Availability

As a Norwegian manufacturer, NORBIT sources components from established suppliers, ensuring reliability. Systems are available through authorized distributors worldwide, with rapid delivery for standard configurations. Customization for specific frequencies or mounting supports diverse applications.

Technological Edge in Multibeam Sonar

The WINGHEAD i77h pioneered cylindrical ultra-high-resolution curved array technology, offering wider swaths without resolution loss. Advanced signal processing filters noise, enhancing signal-to-noise ratios in turbid waters. Outputs include processed point clouds, water column data, and attribute layers for comprehensive analysis.

For construction surveys, it verifies seabed preparation before installing platforms or cables. In USV operations, low power draw enables extended missions, collecting terabytes of data autonomously.

Regulatory and Adoption Factors

Hydrographic standards from IHO (International Hydrographic Organization) emphasize high-resolution data for safe navigation. The i77h complies, supporting classifications like Order 1a surveys. Adoption grows in Europe, North America, and Asia-Pacific, driven by infrastructure investments.

In renewable energy, precise bathymetry de-risks turbine foundations. For aquaculture, it maps net pen sites and fish farm expansions. Defense applications include mine countermeasures and harbor security.

Consumer and Broader Relevance

While primarily industrial, the i77h indirectly benefits consumers through safer shipping routes, reliable energy supplies, and protected coastlines. Recreational boating gains from updated nautical charts derived from such surveys. Environmental NGOs use similar data for conservation advocacy.
