What is the NORBIT WINGHEAD i77h Multibeam Sonar?

The WINGHEAD i77h represents a breakthrough in sonar technology as the first cylindrical ultra-high-resolution curved array bathymetric system. It integrates a modern analogue and digital platform with advanced signal processing, delivering roll-stabilized bathymetry, high-quality imagery, and backscatter outputs. These features support rapid mobilization and high-performance survey operations across various environments.

Key technical specifications include integrated GNSS/INS for accurate positioning and real-time sound velocity measurement for dependable depth accuracy. The sonar's dedicated pipeline mode optimizes it specifically for pipeline and cable inspection, enhancing its utility in infrastructure maintenance tasks.

This sonar system is built for versatility. Its compact and lightweight form factor allows for straightforward transport and deployment, which is particularly advantageous for operations involving USVs or smaller vessels. The result is consistent, high-quality survey data that professionals rely on for decision-making in marine engineering and environmental monitoring.

Core Functions and Technical Characteristics

The primary function of the **NORBIT WINGHEAD i77h** is to provide precise underwater mapping and imaging. It generates detailed 3D bathymetric models, water column data, and backscatter imagery, which are essential for identifying seabed features, obstacles, and anomalies. The 1024 beams ensure comprehensive coverage with minimal gaps, even at high survey speeds.

Roll stabilization is a standout feature, compensating for vessel motion to maintain data quality during dynamic operations. Combined with real-time sound velocity profiling, it achieves centimeter-level accuracy in depth measurements, critical for engineering projects.

The system's acoustic design excels in shallow waters, where traditional sonars often struggle with multipath echoes or reverberation. Its curved array configuration provides a wide swath width, typically up to 120-140 degrees, allowing efficient coverage of large areas without sacrificing resolution.

Pipeline and Cable Inspection Mode

A specialized pipeline mode adjusts the sonar's transmit and receive patterns to focus on linear assets like subsea pipelines and cables. This mode enhances detection of defects, free spans, and burial status, reducing the need for multiple survey passes and improving operational efficiency.

Integration with Positioning Systems

Seamless integration with GNSS/INS systems ensures georeferenced data with high positional accuracy. This is vital for surveys requiring compliance with international hydrographic standards, such as IHO Order 1.

Use Cases for the WINGHEAD i77h

The **NORBIT WINGHEAD i77h** excels in a range of professional applications. Shallow water bathymetry is one primary use, where it maps riverbeds, estuaries, ponds, harbors, and lakes with exceptional detail. This supports dredging operations, navigation charting, and environmental impact assessments.

Pipeline and cable inspection surveys benefit from the dedicated mode, enabling operators to monitor asset integrity, detect leaks, or plan maintenance. Similarly, inspections of quay walls, bridges, and other marine structures utilize the sonar's high-resolution imagery to identify corrosion, scour, or structural damage.

In uncrewed operations, the system's compact size makes it perfect for USVs and UUVs. Coastal surveys, including beach profiling and nearshore habitat mapping, leverage its performance in variable conditions. These use cases span industries like offshore energy, port management, aquaculture, and scientific research.

For coastal engineers, the WINGHEAD i77h provides data for erosion studies and flood risk modeling. In renewable energy, it aids site selection for wind farms by mapping seabed stability and cable routes.

Why the NORBIT WINGHEAD i77h Matters for Industry

In the global marine survey market, precision and efficiency drive demand for systems like the WINGHEAD i77h. Underwater surveys are foundational to sectors including oil and gas, renewables, telecommunications (for subsea cables), and coastal infrastructure. Accurate data reduces risks, optimizes costs, and ensures regulatory compliance.

The shift toward uncrewed vehicles amplifies the relevance of compact sonars. USVs lower operational costs and personnel exposure, while delivering survey-grade data. The WINGHEAD i77h's compatibility positions it at the forefront of this trend, enabling scalable operations worldwide.

Industrially, the sonar supports the energy transition by facilitating offshore wind farm development and decommissioning of old platforms. In port operations, it enhances safety through regular inspections, minimizing downtime from structural failures.

Its commercial role extends to service providers offering survey-as-a-service. Rental models and integration into survey vessel fleets make it accessible to smaller operators, democratizing high-end technology.
