The **NORBIT WINGHEAD i77h** is a compact, ultra-high-resolution multibeam sonar system engineered for demanding underwater survey applications. This curved array sonar stands out for its ability to generate detailed bathymetric data, making it essential for professionals conducting precision mapping in shallow waters, pipelines, and coastal zones.
Designed by NORBIT Subsea, the WINGHEAD i77h features a lightweight and portable build that facilitates rapid deployment. Its cylindrical array technology provides exceptional resolution, with a beam width of 0.5 × 0.9 degrees across 1024 beams, ensuring high-fidelity imaging even in complex environments.
What is the NORBIT WINGHEAD i77h?
The WINGHEAD i77h represents a breakthrough in sonar technology as the first cylindrical ultra-high-resolution curved array bathymetric system. It integrates advanced analogue and digital platforms with sophisticated signal processing to deliver roll-stabilized bathymetry, high-quality imagery, and backscatter outputs.
Key technical specifications include integrated GNSS/INS for accurate positioning and real-time sound velocity measurement for reliable depth calculations. These features contribute to its industry-leading acoustic robustness, allowing consistent performance across varied conditions.
Its compact design—optimized for uncrewed surface vehicles (USVs)—weighs minimally, enabling easy transport and setup. This portability is crucial for field operations where time and logistics matter.
Core Functions and Technical Capabilities
The primary function of the **NORBIT WINGHEAD i77h** is to produce ultra-high-resolution bathymetric maps. The true 1024-beam beamformer captures fine details, ideal for detecting small features on the seafloor.
A dedicated pipeline mode enhances its utility for inspecting underwater pipelines and cables. This mode optimizes beam patterns and processing for elongated targets, improving detection accuracy during route surveys.
Additional outputs include nadir backscatter and water column data, supporting comprehensive analysis. Roll stabilization compensates for vessel motion, maintaining data quality in rough seas.
Beamforming and Resolution
The system's 0.5 × 0.9-degree beam width sets it apart, offering resolution superior to many competitors in its class. This allows for detailed mapping at depths up to several hundred meters, depending on water conditions.
Positioning and Environmental Integration
Built-in GNSS/INS fusion provides sub-centimeter positioning accuracy. Real-time sound velocity profiling adjusts for water column variations, ensuring depth measurements remain precise.
Use Cases in Marine Surveys
The WINGHEAD i77h excels in shallow water bathymetry, where high resolution reveals subtle seabed topography. It's widely used for harbor and lake surveys, estuary mapping, and pond assessments.
In infrastructure inspection, it supports quay wall, bridge, and structure evaluations. Operators deploy it to identify corrosion, debris, or structural weaknesses without diver intervention.
Pipeline and cable route surveys benefit from the specialized mode, which streamlines free-span detection and burial assessments. This reduces operational risks in offshore energy projects.
For uncrewed operations, its size suits USVs and UUVs, enabling autonomous coastal surveys. This expands access to remote or hazardous areas, minimizing human exposure.
Why the WINGHEAD i77h Matters for Industry
In the global marine survey market, the **NORBIT WINGHEAD i77h** addresses key demands for efficiency and precision. Offshore energy, renewables, and port authorities rely on such systems to comply with regulations and optimize assets.
Its high-resolution data supports environmental impact assessments, aiding sustainable development in coastal zones. For instance, accurate bathymetry informs dredging plans and erosion modeling.
The system's rapid mobilization cuts survey downtime, a critical factor in time-sensitive projects like cable laying for offshore wind farms. This enhances commercial viability in competitive bidding scenarios.
Consumer and Industrial Relevance
While primarily industrial, the WINGHEAD i77h indirectly benefits consumers through safer infrastructure. Reliable pipeline inspections prevent leaks, protecting coastal communities and fisheries.
For industries, it streamlines workflows. USV integration lowers costs compared to manned vessels, democratizing high-end surveys for smaller operators.
