Designed by NORBIT Subsea, the WINGHEAD i77h features a narrow beam width of 0.5 × 0.9 degrees, which allows for exceptional resolution even in shallow waters or complex terrains. Its true 1024-beam beamformer processes signals with high precision, supported by industry-leading acoustic robustness that ensures reliable performance across variable conditions.

What is the NORBIT WINGHEAD i77h Multibeam Sonar?

The WINGHEAD i77h belongs to NORBIT's pioneering WINGHEAD series, recognized as the first cylindrical ultra-high-resolution curved array bathymetric system. Built on a modern analogue and digital platform, it incorporates advanced signal processing to deliver roll-stabilized bathymetry, high-quality imagery, and backscatter outputs. The system's lightweight and compact design facilitates rapid mobilization, easy transport, and deployment from small vessels or USVs.

Key technical characteristics include integrated GNSS/INS for accurate positioning and real-time sound velocity measurement, which enhances depth accuracy. These features make the sonar suitable for a broad spectrum of operational environments, from harbors to coastal zones.

Core Components and Technology

At its heart, the i77h employs a curved array transducer that provides wide swath coverage without compromising resolution. The dedicated pipeline mode optimizes beamforming for inspecting underwater pipelines and cables, a critical function in offshore energy and telecommunications infrastructure maintenance.

The system's processing unit handles data in real-time, outputting cleaned bathymetric models and imagery that surveyors can use immediately for decision-making. This efficiency reduces post-processing time, a major advantage in time-sensitive projects.

Primary Functions and Use Cases

The WINGHEAD i77h excels in shallow water bathymetry, where traditional sonars often struggle with resolution. It maps riverbeds, estuaries, ponds, and lakes with pinpoint accuracy, supporting environmental monitoring and dredging operations.

In infrastructure inspection, the sonar detects anomalies on quay walls, bridges, and other submerged structures. Its pipeline and cable inspection mode identifies corrosion, burial depth issues, or route deviations, preventing costly failures in global energy networks.

For uncrewed operations, the compact form factor integrates seamlessly with USVs and UUVs, enabling autonomous surveys in hazardous or remote areas like coastal zones. Harbor and lake surveys benefit from its high-resolution imagery, aiding navigation safety and port maintenance.

Applications in Detail

• Shallow Water Bathymetry: Produces detailed seafloor maps for navigation and resource exploration.
• Pipeline and Cable Inspection: Specialized mode for linear asset integrity checks.
• Structure Inspections: Assesses quay walls, bridges, and piers for wear or damage.
• River, Estuary, and Pond Surveys: Supports flood risk assessment and ecosystem studies.
• Harbor and Lake Surveys: Enhances safety and maintenance planning.
• USV/UUV Operations: Enables remote, cost-effective data collection.
• Coastal Surveys: Maps dynamic shorelines for erosion analysis and coastal engineering.

These use cases highlight the sonar's versatility, addressing needs in marine construction, offshore oil and gas, renewables, and environmental science.

Why the WINGHEAD i77h Matters for Industry

In the global hydrographic survey market, high-resolution sonar like the WINGHEAD i77h is vital for industries requiring precise underwater data. Offshore energy sectors rely on it for pipeline route surveys and platform site assessments, where inaccuracies can lead to multimillion-dollar delays.

Coastal engineering firms use it to model sediment transport and plan erosion defenses, contributing to resilient infrastructure amid rising sea levels. Port authorities deploy it for routine berth surveys, ensuring safe vessel operations and minimizing downtime.

The shift toward uncrewed systems amplifies its relevance. With USVs reducing crew exposure to rough seas, the i77h's compatibility drives adoption in remote sensing, supporting the marine robotics market's growth.

Technical Advantages Over Competitors

Compared to flat array sonars, the curved design of the WINGHEAD i77h maintains uniform resolution across the swath, reducing artifacts in nadir regions. Its acoustic robustness handles noisy environments better, a key differentiator in reverberant shallow waters.

Integration of positioning and sound velocity sensors streamlines workflows, unlike systems requiring external add-ons. This all-in-one approach lowers operational costs for survey contractors worldwide.

Market Relevance and Commercial Role

The demand for multibeam sonars stems from expanding offshore activities, including wind farm installations and subsea cable laying for global data centers. The WINGHEAD i77h addresses this by offering survey-grade performance in a portable package, appealing to small survey firms and large operators alike.

Regulatory pressures for accurate environmental impact assessments further boost adoption. Agencies worldwide mandate high-resolution bathymetry for permitting dredging or coastal developments, positioning systems like the i77h as compliance tools.

Supply chain dynamics favor compact sonars amid vessel size constraints. NORBIT's manufacturing emphasizes durability with corrosion-resistant materials, ensuring longevity in saltwater exposure.

Competition and Positioning

In a market dominated by established players, the WINGHEAD i77h differentiates through its beam count and resolution at a competitive footprint. It targets the mid-tier segment, bridging consumer-grade echo sounders and enterprise multibeams.

Adoption patterns show growth in Asia-Pacific ports and European renewables, where precision mapping supports net-zero goals.

Operational Deployment and Best Practices

Deploying the WINGHEAD i77h involves mounting the transducer head on a pole or hull, connecting to a topside processor, and calibrating via NORBIT's software suite. Operators appreciate the intuitive interface, which supports QINSy, Hypack, and Navisounder formats for seamless data export.

Maintenance is minimal, with self-diagnostic tools monitoring array health. Firmware updates enhance features like improved noise rejection, keeping systems current without hardware swaps.

Case Studies in Global Use

Surveyors have used the i77h for riverbed mapping in flood-prone estuaries, revealing scour holes that informed bridge reinforcements. In pipeline surveys, it detected free-spans threatening integrity, averting potential leaks.

Harbor authorities report 30% faster survey times versus previous gear, attributed to real-time cleaning algorithms.

Technological Innovations Driving Relevance

NORBIT's platform leverages FPGA-based processing for low-latency beamforming, enabling 10kHz pulse rates in shallow ops. This supports dense point clouds, ideal for volume computations in dredging.

Backscatter and water column data add value for fisheries acoustics or debris detection, expanding beyond pure bathymetry.

Future-Proofing Features

Modular design allows upgrades to higher-frequency variants for even finer resolution. Compatibility with AI-driven data analysis tools positions it for automated feature extraction, like pipeline anomaly spotting.
