NORBIT WINGHEAD i77h: Ultra-High-Resolution Multibeam Sonar

The NORBIT WINGHEAD i77h multibeam sonar delivers precise bathymetric surveys for pipeline inspections, USV operations, and coastal mapping, enabling efficient underwater data collection 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 bathymetric surveys, providing accurate depth measurements and imagery in challenging environments. Its lightweight design supports deployment from uncrewed surface vehicles (USVs), making it ideal for modern survey operations.

The system features a true 1024-beam beamformer, delivering 0.5 × 0.9-degree beam width for exceptional resolution. This allows for precise detection of underwater features, essential for applications like pipeline and cable inspections.

What is the NORBIT WINGHEAD i77h?

The WINGHEAD i77h represents a advancement in sonar technology from NORBIT Subsea. It is the first cylindrical ultra-high-resolution curved array bathymetric system, built on a modern analogue and digital platform with advanced signal processing. Key components include integrated GNSS/INS for positioning accuracy and real-time sound velocity measurement for reliable depth data.

Roll-stabilized bathymetry ensures consistent performance despite vessel motion. The system outputs high-quality imagery and backscatter data, supporting comprehensive analysis of seabeds and structures.

Core Functions and Technical Capabilities

At its core, the WINGHEAD i77h performs multibeam echosounding to create detailed 3D maps of underwater terrain. The dedicated pipeline mode optimizes beam patterns for inspecting subsea pipelines and cables, reducing survey time and improving data quality.

Acoustic robustness handles noisy environments, while the compact form factor—lightweight and portable—facilitates rapid mobilization. It supports high-performance operations across various water depths, from shallow coastal areas to deeper sites.

Beamforming and Resolution

The 1024-beam configuration provides dense coverage, capturing fine details like small obstacles or seabed textures. This resolution surpasses traditional flat-array sonars, offering clearer insights for engineering and environmental assessments.

Positioning and Calibration

Integrated GNSS/INS minimizes positioning errors, critical for georeferenced survey data. Real-time sound velocity profiling corrects for water column variations, ensuring depth accuracy within centimeters.

Key Applications and Use Cases

The WINGHEAD i77h serves diverse sectors, including offshore energy, marine construction, and environmental monitoring. Primary uses include:

• Shallow water bathymetry for port development and dredging.
• Pipeline and cable route surveys for oil, gas, and telecommunications infrastructure.
• Quay wall, bridge, and structure inspections for maintenance and safety.
• Pond, river, and estuary mapping for flood risk and habitat studies.
• Harbour and lake surveys for navigation updates.
• USV and UUV operations for autonomous data collection.
• Coastal surveys for erosion analysis and coastal management.

In offshore wind farm projects, it maps seabeds to identify suitable turbine locations. For cable laying, it detects hazards like boulders or wrecks, preventing costly disruptions.

Why the WINGHEAD i77h Matters for Industry

For marine survey professionals, the WINGHEAD i77h reduces operational costs through efficiency. Its USV compatibility enables surveys in hazardous or remote areas without risking crewed vessels. High-resolution data supports better decision-making, minimizing project overruns.

In the global subsea market, demand for such systems grows with offshore renewable energy expansion. Precise mapping ensures compliance with environmental regulations and optimizes asset installation.

The system's portability addresses logistics challenges in regions like the North Sea, Asia-Pacific ports, and U.S. Gulf Coast, where quick deployment is vital.
