Hydrographic & Sonars

The Kongsberg Group is a high tech multinational corporation with 4,000 employees in more than 20 countries. It is a leader in the field of equipment for hydroraphic survey, underwater positioning, swimmer and mine detection and imaging (T.V. and sonar imaging).

Sonar for underwater inspection & survey of structures

Kongsberg Mesotech pioneered the use of scanning sonar for underwater marine engineering applications. The company is a world leader in the development of products used for visualisation of underwater structures (bridges, docks, piers, dams etc.) and using sonar to support a multitude of underwater construction applications. Underwater inspection of man-made structures is vital as they age. Water currents, corrosion and damage from storms and vessels may impact structural integrity.

Diving inspections are often challenged by high current, deep water, lack of visibility and debris accumulation around the structure. In addition to limiting the diver from completing a thorough inspection, debris build-up around bridge piers is potentially one of the most dangerous conditions the inspection diver faces. It introduces the possibility of entanglement, and even worse, diver entrapment if the debris moves.

High resolution sonar provides superior quality data, and the compact size and portability of the sonar enables quick, frequent monitoring and lower costs. The Kongsberg Mesotech scanning sonar and MS 1000 processing software system is ideal for underwater engineering, search and surveying applications.

MS1000 Scanning Sonar

Single-beam sonars use a single transducer to transmit and receive acoustic energy signals, or "pings". There are two types of single-beam sonar, profiling and imaging. Imaging sonar is primarily used for visual interpretation and uses a fan-shaped acoustic beam to scan a specified area or target. Profiling sonar is primarily used for quantitative measurements where a narrow, conically shaped beam generates a single point for each ping. With single-beam scanning sonar, the smaller and narrower the horizontal beam, the better the resolution.

There are two versions of single-beam sonar heads: high-resolution and domed.

  • Range of products available with depth ratings from 650 to 11,000 metres

  • Variety of frequencies and configurations available

  • Reliable and low maintenance systems

  • Standard telemetry is RS232/RS485, ethernet optional

  • Requires MS 1000 software to operate sonar and process data

M3 Multibeam Sonar

The M3 Sonar is a 2D multibeam system with imaging and profiling capabilities. The M3 Sonar provides high resolution and easy to interpret images by combining the rapid refresh rate of conventional multibeam sonar with image quality comparable to a single beam sonar. Detection of small objects out to 150 metres combined with a 120° to 140° field of view allows the operator to see the complete underwater picture in real-time.
