NORBIT WINGHEAD i77h: Ultra-High-Resolution Multibeam Sonar

The NORBIT WINGHEAD i77h multibeam sonar delivers precise bathymetric surveys for pipelines, coastal areas, and USVs, enabling efficient underwater mapping worldwide.

The **NORBIT WINGHEAD i77h** is a compact, ultra-high-resolution multibeam sonar system designed for demanding underwater survey applications. Engineered by NORBIT Subsea, this curved array sonar excels in bathymetric surveys, pipeline and cable inspections, and operations with uncrewed surface vehicles (USVs). Its lightweight design facilitates rapid deployment in diverse environments, from shallow waters to coastal zones.

At the core of the WINGHEAD i77h's capabilities is its advanced beamforming technology, which utilizes a true 1024 beams beamformer. This provides a beam width of 0.5 × 0.9 degrees, ensuring ultra-high-resolution data collection even in challenging conditions. The system's industry-leading acoustic robustness maintains reliable performance across varying water depths and seabed types.

WINGHEAD i77h Key Technical Features

The NORBIT WINGHEAD i77h integrates GNSS/INS technology for precise positioning, combined with real-time sound velocity measurement. These features deliver accurate depth measurements, critical for professional hydrographic surveys. Its roll-stabilized bathymetry output, along with high-quality imagery and backscatter data, supports comprehensive seabed analysis.

A dedicated pipeline mode optimizes the sonar for inspecting underwater pipelines and cables. This mode enhances detection of anomalies, coatings, and structural integrity, making it invaluable for energy and offshore industries. The cylindrical ultra-high-resolution curved array design represents a pioneering approach in multibeam sonar technology, built on a modern analogue and digital platform with advanced signal processing.

Compactness is a standout attribute: the i77h's lightweight build allows for easy transport and mobilization. This portability suits field operations where speed is essential, such as emergency response surveys or remote site assessments. The system's versatility extends to uncrewed vehicles, enabling autonomous data collection without compromising quality.

Primary Applications of WINGHEAD i77h

In shallow water bathymetry, the WINGHEAD i77h maps riverbeds, ponds, estuaries, harbors, and lakes with exceptional detail. These surveys inform dredging operations, navigation safety, and environmental monitoring. For instance, harbor authorities rely on such data to maintain safe depths for commercial shipping.

Pipeline and cable inspection surveys benefit from the sonar's high-resolution imaging. Operators in the oil and gas sector use it to detect leaks, corrosion, or burial issues along subsea infrastructure. Similarly, telecommunications companies inspect undersea cables for damage from anchors or natural events.

Structure inspections, including quay walls, bridges, and piers, leverage the system's backscatter capabilities to identify scour, cracks, or debris accumulation. Coastal surveys map erosion patterns and sediment transport, aiding coastal management and climate resilience projects.

USV and UUV Integration

The WINGHEAD i77h is optimized for uncrewed surface vehicles (USVs) and underwater vehicles (UUVs). Its low power consumption and small form factor make it ideal for autonomous missions, reducing operational costs and human risk in hazardous areas like contaminated waters or deep coastal zones.

Why WINGHEAD i77h Matters for Industry

For marine construction firms, the sonar provides essential data for site preparation, ensuring stable foundations for offshore wind farms, platforms, and ports. Accurate bathymetry minimizes risks during piling and trenching, optimizing project timelines and budgets.

In environmental science, high-resolution surveys track habitat changes, supporting marine protected area management. Fisheries agencies use backscatter data to assess fish stocks and seabed biodiversity, contributing to sustainable resource policies.

The global hydrographic survey market relies on tools like the WINGHEAD i77h for compliance with international standards, such as those from the International Hydrographic Organization (IHO). Its precision meets order 1a specifications for critical navigation charts.

Adoption in USVs aligns with the growing trend toward autonomous marine operations. As regulations evolve to permit uncrewed surveys, systems like this enable scalable data acquisition across vast areas, from Arctic routes to tropical reefs.

Market Relevance and Commercial Role

The WINGHEAD i77h addresses key demands in the expanding subsea survey sector, driven by offshore energy transitions, port expansions, and coastal defense needs. Its multi-output capabilities—bathymetry, imagery, backscatter—reduce the need for multiple sensors, streamlining workflows and cutting costs.

Competition includes other multibeam sonars from manufacturers like Teledyne RESON and Kongsberg, but the i77h's compact design and pipeline mode set it apart for niche applications. Supply chains for sonar components benefit from NORBIT's focus on modular, upgradeable systems, ensuring long-term viability.

Regulatory factors, such as emissions standards for survey vessels and data privacy for autonomous ops, influence adoption. The system's efficiency supports greener operations by minimizing vessel time on water.

Consumer and Broader Relevance

While primarily industrial, the WINGHEAD i77h indirectly benefits consumers through safer shipping routes, reliable energy supplies, and protected coastlines. Recreational boating areas gain from updated charts derived from its surveys, enhancing safety for leisure users worldwide.

In aquaculture, precise seabed mapping optimizes farm layouts, supporting sustainable seafood production. Tourism operators in lake and river regions use survey data for eco-friendly developments.

Technology and Innovation Behind It

The sonar's curved array transducer covers wide swaths efficiently, with equi-angular beams maintaining uniform resolution across the full swath. Advanced signal processing filters noise from multipath echoes, common in shallow or reverberant environments.

Integration with modern software suites allows real-time 3D visualization and cloud uploading, accelerating data delivery to clients. Firmware updates enhance compatibility with emerging USV platforms.

Global Deployment Examples

Operators worldwide deploy the i77h in European ports for routine maintenance, Asian shipyards for construction support, and North American rivers for flood risk assessment. Its robustness handles temperate to tropical waters, with minimal recalibration.

In renewable energy, offshore wind developers map turbine sites, ensuring geotechnical stability. Cable-laying for interconnectors between grids relies on its inspection prowess post-installation.

Challenges and Solutions

Common challenges like biofouling or strong currents are mitigated by the system's high acoustic power and adaptive processing. Operators appreciate the quick-setup calibration routines.
