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 shallow water bathymetry, pipeline and cable route surveys, and operations with uncrewed surface vehicles (USVs). Its lightweight build supports rapid deployment in diverse marine environments, making it essential for hydrographic professionals globally.

The system features a true 1024-beam beamformer with 0.5 × 0.9-degree beam width, enabling exceptional resolution for accurate depth measurements and imagery. Integrated GNSS/INS positioning and real-time sound velocity profiling ensure reliable data even in challenging conditions. A dedicated pipeline mode optimizes performance for inspecting subsea infrastructure, providing high-quality backscatter and roll-stabilized bathymetry.

What is the NORBIT WINGHEAD i77h?

The WINGHEAD i77h represents a breakthrough in cylindrical ultra-high-resolution sonar technology from NORBIT Subsea. Built on a modern analogue-digital platform, it processes advanced signals for superior acoustic performance. The curved array design covers wide swaths efficiently, ideal for high-precision surveys where traditional systems fall short.

Key technical properties include its compact size and low weight, facilitating transport and integration onto small vessels or USVs. It outputs clean bathymetric data, forward-looking imagery, and backscatter, supporting applications from harbor maintenance to riverbed analysis. This versatility positions it as a go-to tool for marine surveyors seeking efficiency without compromising detail.

Core Technical Specifications

At its heart, the i77h employs industry-leading acoustic robustness to maintain data integrity amid noise or multipath interference. The 1024 beams deliver dense point clouds, critical for detecting small features like seabed hazards or structural defects. Real-time corrections via integrated sensors minimize post-processing needs, accelerating project timelines.

Primary Functions and Capabilities

The sonar's functions center on high-resolution imaging and mapping. It performs roll-stabilized bathymetry, automatically adjusting for vessel motion to produce consistent soundings. Backscatter analysis reveals seabed composition, aiding geologists and engineers in material identification.

In pipeline mode, it focuses beams for elongated targets, enhancing detection of cables, pipes, and associated features. This mode reduces false positives and improves coverage along linear routes, vital for energy and telecom sectors maintaining offshore assets.

Integration with Modern Survey Platforms

Designed for USVs and UUVs, the i77h interfaces seamlessly with autonomous systems. Its low power draw and rugged enclosure suit extended missions in remote areas. Operators benefit from user-friendly software that visualizes data in real-time, enabling on-the-spot decisions.

Use Cases in Marine Surveys

NORBIT WINGHEAD i77h shines in shallow water bathymetry, charting depths in ponds, rivers, estuaries, harbors, and lakes. These surveys support dredging, navigation safety, and environmental monitoring by providing detailed topographic models.

Pipeline and cable inspections represent a core application, where precise route tracking prevents disruptions and ensures compliance with safety standards. Structure inspections for quays, bridges, and piers detect erosion or damage early, extending infrastructure life.

Coastal surveys leverage its resolution for erosion studies, habitat mapping, and flood risk assessment. In USV operations, it enables cost-effective coverage of large areas without crewed vessels, democratizing access to advanced hydrography.

Why the WINGHEAD i77h Matters for Industry

For marine contractors, the i77h reduces operational costs through quick setup and high data quality. Its accuracy meets international hydrographic standards, minimizing rework and disputes. In offshore energy, precise inspections mitigate risks like leaks or crossings.

Environmental agencies use it for baseline mapping in protected waters, tracking changes from climate or human activity. Port authorities rely on regular surveys for safe vessel traffic, with the sonar's efficiency supporting frequent updates.

Advantages Over Traditional Sonars

Unlike flat array systems, the curved design of the i77h provides uniform resolution across swaths, eliminating gaps in coverage. The 1024 beams outperform competitors in point density, crucial for 3D modeling of complex seabeds.

Consumer and Industrial Relevance Worldwide

While primarily industrial, the i77h indirectly benefits consumers through safer shipping routes and reliable utilities. Recreational boating areas gain from harbor surveys, reducing accident risks. Fisheries management employs its habitat data for sustainable practices.

In the global market, demand stems from expanding offshore wind, subsea telecom cables, and coastal development. The system's portability suits emerging markets with limited infrastructure, broadening hydrographic services.

Market Role and Commercial Significance

The NORBIT WINGHEAD i77h holds a strong position in the multibeam sonar sector, known for pioneering cylindrical arrays. Its adoption by survey firms underscores reliability in demanding conditions. Competition includes larger systems, but the i77h's USV focus targets a growing niche.

Supply chains benefit from standardized components, easing maintenance. Regulations like IHO standards drive demand for high-resolution tools, with the i77h's compliance enhancing its appeal.

Technology and Innovation Behind the Sonar

Advanced signal processing filters noise, delivering clean datasets. The platform supports future upgrades, ensuring longevity. Acoustic robustness handles turbid waters or heavy traffic, common in industrial zones.

Integration with QPS Qimera software streamlines workflows from acquisition to analysis, a boon for multidisciplinary teams.

Deployment and Operational Efficiency

Operators mount the i77h on pole systems or hulls effortlessly. Calibration is streamlined, with self-tests verifying performance pre-survey. Data rates support real-time mosaicking, ideal for time-sensitive projects.

Challenges and Best Practices

Optimal use requires understanding sound velocity profiles, addressed by the integrated profiler. In very shallow waters, nadir gaps are minimal due to tight beams. Training ensures maximum utilization of pipeline mode.

Global Adoption Trends

Survey companies worldwide deploy the i77h for its balance of performance and practicality. USV integrations grow with autonomy trends, positioning NORBIT as a leader in compact hydrography.
