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 surveys, construction monitoring, and inspections using uncrewed surface vehicles (USVs).
Engineered by NORBIT Subsea, the WINGHEAD i77h features a 0.5 × 0.9-degree beam width, providing exceptional resolution for detailed seabed mapping. Its true 1024-beam beamformer ensures precise results across diverse applications.
WINGHEAD i77h Core Functions and Technical Capabilities
The system's modern analogue and digital platform incorporates advanced signal processing for rapid mobilization and high-performance operations. It delivers roll-stabilized bathymetry, high-quality imagery, and backscatter outputs, making it reliable in varied conditions.
Integrated GNSS/INS technology provides accurate positioning, while real-time sound velocity measurement enhances depth accuracy. These features support consistent performance in shallow waters and complex environments.
A dedicated pipeline mode optimizes the WINGHEAD i77h for pipeline and cable inspections, addressing critical needs in subsea infrastructure maintenance. The lightweight, compact design facilitates easy deployment and transport, ideal for field operations.
Key Applications in Marine and Coastal Surveys
The WINGHEAD i77h supports shallow water bathymetry, essential for port development and environmental monitoring. It is widely used in pipeline and cable inspection surveys to detect anomalies and ensure asset integrity.
Quay wall, bridge, and structure inspections benefit from its high-resolution imaging, enabling precise assessments of underwater infrastructure. Pond, river, and estuary surveys leverage its portability for inland waterway mapping.
Harbor and lake surveys represent another core use case, where the system's acoustic robustness delivers reliable data despite variable conditions. Its compatibility with USVs and UUVs extends capabilities to autonomous operations, reducing operational risks.
Coastal surveys utilize the i77h for mapping dynamic shorelines and nearshore features, supporting coastal management and erosion studies.
Why the WINGHEAD i77h Matters for Industry Professionals
For marine surveyors, the WINGHEAD i77h offers industry-leading acoustic robustness, ensuring data quality in noisy or reverberant environments. This reliability minimizes survey downtime and repeat visits, optimizing project timelines.
In the global subsea sector, precise bathymetry is vital for offshore energy, telecommunications, and renewable projects. The i77h's high-resolution data informs engineering decisions, from route planning to installation verification.
USV integration aligns with the shift toward unmanned systems, lowering costs and enhancing safety by reducing human exposure to hazardous areas. This positions the product as a key enabler in modern hydrographic workflows.
Design Advantages for Deployment Flexibility
The compact form factor of the WINGHEAD i77h—lightweight and portable—suits small vessels and USVs, broadening accessibility for mid-sized survey firms. Quick setup supports agile operations in remote or time-sensitive projects.
As the first cylindrical ultra-high-resolution curved array bathymetric system in the WINGHEAD series, it sets a benchmark for resolution and stability. Roll stabilization compensates for vessel motion, delivering clean nadir and outer beam data.
Performance in Challenging Environments
In pipeline inspections, the dedicated mode enhances target resolution for small defects. Real-time corrections for sound velocity profiles ensure depth accuracy within centimeters, critical for compliance and safety.
Integration with Survey Workflows
The system outputs processed data compatible with standard hydrographic software, streamlining post-processing. This interoperability boosts efficiency for surveyors using QINSy, Hypack, or similar platforms.
Market Relevance in Global Hydrography
The demand for high-resolution sonar grows with expanding offshore wind farms, subsea cables for data centers, and coastal resilience projects. The WINGHEAD i77h meets these needs with proven performance in commercial surveys.
Competition includes systems from Teledyne RESON and R2Sonic, but the i77h's balance of resolution, compactness, and price point appeals to USV operators and inspection specialists. Its focus on pipeline modes differentiates it in asset integrity markets.
Supply chain stability for sonar components benefits from NORBIT's manufacturing in Norway, supporting consistent availability amid global semiconductor pressures. Adoption spans Europe, North America, and Asia-Pacific hydrographic services.
Consumer and Industrial Use Case Expansion
While primarily industrial, the WINGHEAD i77h serves research institutions mapping lakes and rivers for environmental science. Drones and small boats equipped with this sonar democratize high-end surveying for academia and local agencies.
In aquaculture, it maps seabed conditions for farm site selection, aiding sustainable fish farming expansion. Estuary surveys support fisheries management by tracking habitat changes.
Regulatory and Safety Compliance
High-accuracy data from the i77h aids compliance with international hydrographic standards like IHO S-44. This ensures surveys meet requirements for navigation charts and offshore permitting.
Technological Edge in Multibeam Sonar
The 1024-beam configuration covers wide swath widths at high frequencies, ideal for feature detection in 10-100m depths. Equi-angular beam spacing maintains uniform resolution across the swath.
Advanced signal processing suppresses multipath interference, common in shallow or structured waters. This results in cleaner point clouds for 3D modeling of wrecks, pipelines, and reefs.
Operational Efficiency Gains
Surveyors report faster data acquisition with the i77h compared to older multibeam systems, thanks to its efficient beamforming. Reduced processing time allows quicker delivery of survey reports.
Low power consumption suits battery-powered USVs, enabling extended missions without refueling. Maintenance is simplified with modular transducers and field-serviceable electronics.
Global Adoption and Case Studies
In European harbors, the i77h has mapped quay walls for renovation projects, identifying scour and structural weaknesses. North American river surveys use it for flood risk assessment.
Asian coastal developments employ the system for pre-construction bathymetry, ensuring stable foundations for ports and bridges. These applications underscore its versatility across continents.
Future-Proofing Survey Operations
Software updates for the WINGHEAD i77h add features like water column imaging, expanding to fisheries and gas seep detection. This upgradability extends the system's lifecycle in evolving markets.
Integration with AI-driven data cleaning tools enhances automation, appealing to operators seeking to scale survey volumes amid labor shortages.
Company Behind the Technology
NORBIT Subsea, part of the NORBIT group, specializes in sonar solutions for hydrography and offshore industries. Their expertise in curved array technology drives innovations like the WINGHEAD series.
