NORBIT WINGHEAD i77h Multibeam Sonar: Precision Survey Tech

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

NORBIT WINGHEAD i77h is a compact, ultra-high-resolution multibeam sonar system designed for precise bathymetric surveys and underwater inspections.

This curved array sonar excels in shallow water mapping, pipeline and cable route inspections, and operations with uncrewed surface vehicles (USVs), providing reliable data across diverse marine environments.

What is the NORBIT WINGHEAD i77h Multibeam Sonar?

The NORBIT WINGHEAD i77h represents advanced sonar technology tailored for subsea survey applications. As part of NORBIT Subsea's WINGHEAD series, it is the first cylindrical ultra-high-resolution curved array bathymetric system, built on a modern analogue and digital platform with sophisticated signal processing.

Key technical characteristics include a 0.5 × 0.9-degree beam width, enabling ultra-high-resolution data capture, and a true 1024-beam beamformer for exceptional precision. Integrated GNSS/INS technology ensures accurate georeferencing, while real-time sound velocity measurement enhances depth accuracy in varying water conditions.

Its lightweight and compact design facilitates easy deployment, transport, and rapid mobilization, making it ideal for field operations where mobility is critical.

Core Functions and Outputs

The system delivers roll-stabilized bathymetry, high-quality imagery, and backscatter data, supporting comprehensive analysis of underwater topography and features. Industry-leading acoustic robustness maintains performance even in noisy or challenging acoustic environments.

A dedicated pipeline mode optimizes beamforming and processing specifically for pipeline and cable inspection, improving detection and mapping efficiency.

Primary Use Cases for WINGHEAD i77h

NORBIT WINGHEAD i77h supports a range of professional survey applications globally. These include shallow water bathymetry for coastal and inland waters, essential for navigation, dredging, and environmental monitoring.

Pipeline and cable inspection surveys benefit from its high-resolution imaging, aiding in maintenance, route clearance, and integrity assessments in offshore energy sectors.

Structure inspections, such as quay walls, bridges, and marine infrastructure, leverage its precision to identify defects or erosion without extensive diver intervention.

• Pond, river, and estuary surveys for hydrology and flood risk management.
• Harbour and lake surveys for port development and sediment studies.
• USV and UUV operations, extending survey reach in remote or hazardous areas.
• Coastal surveys for erosion monitoring and shoreline management.

These use cases highlight its versatility across commercial, governmental, and research applications in marine science and engineering.

Why the WINGHEAD i77h Matters for Industry

In the global hydrographic survey market, the NORBIT WINGHEAD i77h addresses key demands for high-resolution data in compact formats. Industries reliant on accurate underwater mapping—such as offshore oil and gas, renewable energy, port authorities, and environmental agencies—depend on such systems to minimize risks and optimize operations.

Its USV compatibility aligns with the rising adoption of autonomous survey technologies, reducing personnel exposure to harsh conditions and lowering operational costs. High-resolution outputs support detailed 3D models, crucial for infrastructure planning and regulatory compliance.

For marine construction firms, the system's pipeline mode streamlines inspections, ensuring compliance with international safety standards and preventing costly downtime.

Technical Advantages Over Traditional Systems

Unlike older multibeam sonars with wider beam widths, the i77h's narrow beams capture finer details at greater ranges, improving point density and data quality. The cylindrical array design provides uniform swath coverage regardless of vessel motion, enhanced by roll stabilization.

Real-time processing capabilities allow operators to make immediate decisions on-site, accelerating project timelines in time-sensitive surveys.

Global Market Relevance of Multibeam Sonar Technology

Multibeam sonar systems like the WINGHEAD i77h play a pivotal role in the expanding subsea survey sector, driven by offshore wind farm developments, subsea cable networks for telecommunications and power, and climate-driven coastal resilience projects worldwide.

The shift toward uncrewed vehicles amplifies demand for compact, high-performance sonars, as USVs enable surveys over larger areas with reduced logistics. In regions like Europe, Asia-Pacific, and North America, regulatory mandates for regular infrastructure inspections further underscore commercial importance.

Competition exists from established players in hydrographic equipment, but NORBIT's focus on integrated, user-friendly systems positions the i77h for growth in precision survey niches.

Deployment and Operational Flexibility

The NORBIT WINGHEAD i77h's design emphasizes ease of use. Weighing minimally and mounting easily on small vessels or USVs, it supports surveys in confined spaces like rivers or harbors where larger systems falter.

Advanced signal processing filters noise effectively, ensuring consistent results in turbid waters or near industrial noise sources common in pipeline vicinities.

Operators benefit from intuitive software interfaces that process data in real-time, generating cleaned bathymetric maps and imagery exportable to standard GIS formats.

Integration with Modern Survey Workflows

Compatibility with GNSS/INS units allows seamless positioning data fusion, critical for centimeter-level accuracy required in engineering surveys. Sound velocity profiling integration corrects for water column variations, vital in stratified or temperature-gradient environments.

Applications in Renewable Energy and Infrastructure

As global investments in offshore wind surge, the WINGHEAD i77h supports site characterization, cable route surveys, and foundation inspections. High-resolution backscatter helps identify seabed hazards like boulders or soft sediments.

In port and harbor management, regular bathymetric updates using this sonar prevent silting issues and guide dredging operations efficiently.

River and estuary surveys aid flood modeling and habitat restoration, contributing to environmental sustainability efforts.

Challenges Addressed by WINGHEAD i77h Design

Traditional survey sonars often struggle with size, power demands, or resolution trade-offs. The i77h overcomes these with its low SWaP (Size, Weight, and Power) profile, making it suitable for battery-powered USVs on extended missions.

Acoustic robustness mitigates multipath interference near structures, a common issue in quay wall or bridge inspections.
