NORBIT WINGHEAD i77h: Ultra-High-Resolution Multibeam Sonar

The NORBIT WINGHEAD i77h multibeam sonar delivers precise bathymetric surveys for pipeline inspections, coastal mapping, and USV operations, enabling efficient underwater data collection worldwide.

NORBIT WINGHEAD i77h is a compact, ultra-high-resolution multibeam sonar system designed for detailed underwater surveying. This curved array sonar excels in bathymetric surveys, construction monitoring, and inspections using uncrewed surface vehicles (USVs). Its lightweight build supports rapid deployment in diverse marine environments, from shallow waters to coastal zones.

The system features a 0.5 × 0.9-degree beam width, providing exceptional resolution for mapping seafloors and structures. With a true 1024-beam beamformer, it generates precise, reliable data even in challenging conditions. Integrated GNSS/INS technology ensures accurate georeferencing, while real-time sound velocity measurement enhances depth accuracy across varying water columns.

NORBIT WINGHEAD i77h Core Functions and Technology

At its core, the NORBIT WINGHEAD i77h operates as a cylindrical ultra-high-resolution curved array bathymetric system. This design, pioneered in the WINGHEAD series, uses advanced analogue and digital signal processing for roll-stabilized bathymetry, high-quality imagery, and backscatter outputs. The dedicated pipeline mode optimizes performance for inspecting underwater pipelines and cables, reducing survey times and improving data quality.

Acoustic robustness is a standout feature, allowing consistent operation amid noise, multipath reflections, or platform motion. The system's modern platform supports quick mobilization, making it ideal for time-sensitive projects. Operators benefit from real-time data processing, enabling on-the-spot decisions during surveys.

Beamforming and Resolution Advantages

The 1024-beam beamformer forms the technological backbone, steering beams dynamically for uniform coverage. This results in dense point clouds with minimal gaps, crucial for detecting small features like debris or erosion. Compared to traditional flat-array sonars, the curved array maintains resolution across wide swath widths, up to 140 degrees depending on depth.

Positioning and Environmental Integration

Built-in GNSS/INS fusion provides sub-centimeter positioning accuracy when paired with RTK corrections. Real-time sound velocity profiling corrects for stratification, ensuring depth measurements remain reliable in thermoclines or salinity gradients. These integrations minimize post-processing needs, accelerating workflows for survey teams.

Key Applications of NORBIT WINGHEAD i77h

The NORBIT WINGHEAD i77h serves critical roles in marine industries globally. Primary uses include shallow water bathymetry for port development and dredging operations. It maps riverbeds, estuaries, harbors, and lakes with high fidelity, supporting infrastructure planning and maintenance.

Pipeline and cable route surveys represent a core strength, where the dedicated mode identifies crossings, free spans, and burial depths. Structure inspections for quays, bridges, and offshore platforms detect corrosion, scour, or damage without diver intervention. USV and UUV compatibility extends reach to hazardous or remote areas, enhancing safety and cost-efficiency.

Coastal surveys benefit from its portability, aiding erosion studies, habitat mapping, and renewable energy site assessments like offshore wind farms. In pond and river surveys, it provides volumetric data for sediment management and flood risk modeling.

USV and Autonomous Operations

Optimized for uncrewed vehicles, the sonar's low power draw and compact size (under 10kg) fit small USVs. This enables autonomous coverage of large areas, reducing manpower and fuel costs. Real-time data streaming supports remote monitoring, vital for extended missions.

Why NORBIT WINGHEAD i77h Matters for Industry

For marine contractors and survey firms, the NORBIT WINGHEAD i77h addresses demands for higher resolution without sacrificing coverage. Global offshore energy expansion, port modernization, and subsea infrastructure growth drive adoption. Its ability to deliver IHO-compliant data in shallow waters fills a gap for high-spec surveys where larger systems falter.

Industrially, it supports the blue economy by enabling precise resource mapping for aquaculture, fisheries, and seabed mining. Regulatory compliance for asset integrity—mandated by bodies like IMO and national maritime authorities—relies on such tools for verifiable inspections. Competition from systems like Teledyne RESON or R2Sonic exists, but the i77h's pipeline focus and USV integration provide differentiated value.

Supply chain resilience benefits from its modular design, using standard components for easier maintenance worldwide. Demand stems from rising subsea activities, with the multibeam sonar market projected to grow amid energy transitions and coastal urbanization. Availability through NORBIT's network ensures global access, though lead times vary by configuration.

Technical Specifications and Performance

The NORBIT WINGHEAD i77h operates at 300-400kHz frequencies, balancing resolution and range for depths up to 300m in shallow configs. Swath coverage reaches 7-8 times water depth, with nadir resolution down to 1cm. Power requirements are modest at 20-40W, suiting battery-powered USVs.

Outputs include processed bathymetry in X,Y,Z formats, alongside water column and snippet data for advanced analysis. Software integration with QINSy, Hypack, or Norbit's WINGFIELD suite streamlines workflows. Environmental sealing to 100m depth rating supports pole-mount or over-side deployments.

Pipeline Inspection Mode Details

This mode employs narrower beams along-track for elongated targets, enhancing detection of anomalies like leaks or coatings. Backscatter analysis reveals material changes, aiding integrity assessments without ROVs. Data density supports 3D modeling for engineering reports.

Consumer and End-User Relevance

While primarily industrial, the NORBIT WINGHEAD i77h indirectly benefits consumers through safer infrastructure. Accurate harbor surveys prevent dredging accidents, ensuring reliable shipping for goods. Coastal mapping informs erosion defenses, protecting communities from sea-level rise.
