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 in challenging environments.

The **NORBIT WINGHEAD i77h** is a compact, ultra-high-resolution multibeam sonar system designed for advanced underwater surveying. This curved array sonar excels in delivering detailed bathymetric data, making it essential for applications like pipeline and cable inspections, coastal surveys, and operations with uncrewed surface vehicles (USVs).

Developed by NORBIT Subsea, the WINGHEAD i77h stands out for its lightweight and portable design, facilitating easy deployment in diverse environments from shallow waters to harbors and rivers. Its true 1024-beam beamformer ensures exceptional resolution with a 0.5 × 0.9-degree beam width, providing precise and reliable results even in demanding conditions.

What is the NORBIT WINGHEAD i77h?

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 analogue and digital platforms with advanced signal processing to support rapid mobilization and high-performance surveys. Key features include roll-stabilized bathymetry, high-quality imagery, and backscatter outputs, all critical for professional hydrographic work.

Integrated GNSS/INS technology provides accurate positioning, while real-time sound velocity measurement enhances depth accuracy. These elements make the system robust against acoustic interference, ensuring consistent performance across various water depths and conditions.

Core Functions and Technical Characteristics

At its core, the WINGHEAD i77h functions as a multibeam echo sounder, emitting acoustic pulses to map the seafloor and underwater structures with high precision. The system's dedicated pipeline mode optimizes it for inspecting subsea pipelines and cables, identifying anomalies, coatings, and burial depths efficiently.

With 1024 beams, it captures dense point clouds for ultra-high-resolution imaging, surpassing traditional multibeam sonars in detail. The curved array design maintains consistent swath coverage regardless of vessel roll or pitch, a vital advantage for survey vessels and USVs.

Real-time processing capabilities allow operators to generate cleaned bathymetry, snippets, and water column data on the fly. This supports immediate decision-making in time-sensitive operations like construction support or environmental monitoring.

Beamforming and Resolution Advantages

The true 1024-beam beamformer is a standout feature, enabling finer angular resolution than multi-sector systems. This results in sharper seafloor imagery and reduced artifacts, crucial for detecting small features like rocks, wrecks, or erosion patterns.

Positioning and Environmental Adaptability

GNSS/INS integration delivers sub-centimeter positioning accuracy when paired with appropriate corrections. Real-time sound velocity profiling compensates for water column variations, ensuring depth measurements remain reliable in stratified or turbid waters.

Key Use Cases in Global Markets

The WINGHEAD i77h serves a broad spectrum of applications, addressing needs in marine construction, offshore energy, environmental science, and port management worldwide.

• Shallow Water Bathymetry: Maps riverbeds, ponds, estuaries, and coastal zones for flood risk assessment, dredging planning, and habitat studies.
• Pipeline and Cable Route Surveys: Inspects subsea infrastructure for integrity, free spans, and trenching verification, critical for oil, gas, and renewable energy sectors.
• Structure Inspections: Evaluates quay walls, bridges, piers, and offshore platforms for corrosion, scour, and structural changes.
• Harbor and Lake Surveys: Supports navigation safety, sediment management, and infrastructure maintenance in busy ports.
• USV/UUV Operations: Enables autonomous surveys in hazardous or remote areas, reducing crew exposure and operational costs.
• Coastal Surveys: Monitors erosion, beach nourishment, and nearshore developments for climate resilience projects.

These use cases highlight the system's versatility, making it relevant for governments, engineering firms, research institutions, and energy companies globally.

Why the WINGHEAD i77h Matters for Industry

In the global hydrographic survey market, high-resolution sonar like the WINGHEAD i77h drives efficiency and safety. Offshore wind farms, subsea cable deployments for telecom and power, and pipeline networks expanding in regions like the North Sea, Gulf of Mexico, and Asia-Pacific demand precise seabed mapping to minimize risks and costs.

The compact form factor—lightweight at under 10 kg—allows integration with small vessels or drones, democratizing access to professional-grade data for smaller operators. This supports the shift toward sustainable energy infrastructure, where accurate surveys ensure optimal cable routing and foundation placement.

For environmental applications, the system's backscatter and imagery capabilities aid in habitat mapping, detecting invasive species, or assessing pollution impacts, aligning with international regulations like those from the International Hydrographic Organization (IHO) standards.

Advantages in USV and Autonomous Operations

As uncrewed systems proliferate, the WINGHEAD i77h's low power consumption and Ethernet interface enable seamless integration. This facilitates repeat surveys for change detection, vital for dynamic environments like river mouths or construction sites.

In industrial contexts, it reduces survey times by up to 50% compared to lower-resolution systems, per typical industry benchmarks, accelerating project timelines for renewable energy and telecom projects.

Market Relevance and Commercial Role

The global multibeam sonar market is growing with rising offshore activities, projected to expand due to renewables and subsea infrastructure. The WINGHEAD i77h positions NORBIT as a leader in compact, high-performance systems, competing with larger systems from Kongsberg or Teledyne while offering superior portability.

Demand stems from energy transitions, with offshore wind capacity expected to triple by 2030, necessitating extensive seabed surveys. Pipeline inspections remain steady in oil and gas maintenance, while coastal resilience projects gain traction amid climate change.

Supply chains for sonar manufacturing rely on advanced transducers and processing chips, with NORBIT's Norway-based production benefiting from European precision engineering. Adoption is strong in Europe, North America, and Asia, supported by rental fleets and service providers.

Technological Edge and Competition

What sets the WINGHEAD i77h apart is its cylindrical array, providing uniform beam spacing across the full swath—up to 140 degrees. This contrasts with flat array sonars that degrade at swath edges, ensuring consistent quality.

Competitors offer similar resolutions but often require larger vessels or more power. The i77h's robustness in noisy environments, thanks to advanced noise rejection algorithms, makes it ideal for urban harbors or busy shipping lanes.

Regulatory compliance with IHO Special Order standards ensures survey data meets international cartographic requirements, enhancing its commercial appeal for certified hydrographic services.

Deployment and Operational Benefits

Operators appreciate the system's quick setup—typically under 30 minutes—and user-friendly software interface. Data outputs in standard formats like QPS QIMERA or Hypack facilitate integration with popular processing suites.

In field operations, its IP67-rated enclosure withstands harsh marine conditions, from saltwater corrosion to temperature extremes. This durability extends service life, reducing total cost of ownership for frequent users.

Consumer and Industrial Relevance Worldwide

While primarily industrial, the WINGHEAD i77h indirectly benefits consumers through safer navigation in ports, reliable energy supply via protected infrastructure, and informed coastal management that mitigates flood risks. For industries, it streamlines compliance with environmental impact assessments and asset integrity programs.

In emerging markets like Southeast Asia and Africa, where port expansions are booming, affordable high-res sonars like this enable local firms to compete globally.
