Widest swath, full ocean depth, max. 11000 m
The modular, state-of-the-art EM 124 performs accurate, high resolution seabed mapping in shallow to full ocean depth. The successor to the EM 122, the EM 124's broad range of functionality supports simultaneous collection of multiple data types, saving time in the planning, execution, and analysis phase. A low noise echo sounder, EM 124 delivers superior data that requires minimal post-processing.
Modular and flexible design
The EM 124 uses state-of-the-art electronics and separate transmit and receive transducers in a Mills Cross configuration. It utilizes the same field-proven electronics and transducers as the EM 122, making it easy to upgrade. The design is highly modular and flexible with compact electronics for easier and faster installation. The flexible transducer design makes it possible to tailor they system to almost any required size. The largest standard size, 0.5 x 1 degrees, gives the ultimate system performance in terms of resolution and range, while a smaller 4 x 4 degrees solution allows wider full ocean depth surveys even on smaller vessels.
Acoustic ice protection windows can be offered for vessels going to the ice rand and for ice breakers. Both TX and RX ice windows are made of hyperlast, reinforced with titanium rods, proven to withstand surveys across the North Pole.
Full seabed coverage
The transmit fan can be divided into 16 individual sectors in dual swath mode. This allows for unique control of the transmit fan, enabling active stabilization in real time to correct for any yaw and pitch movement of the vessel, while roll stabilization is applied on the receiving beams. The result is a stabilized system—full ensonification of the seabed with equally distributed footprints, in all types of weather conditions, leaving no gaps or holes in the mapped area. All beams are maintained and automatically adjusted according to achievable coverage or operator defined limits. Up to 1600 individual beams are available in dual swath mode. The two individual transmitting fans are generated with a small difference in tilt to provide a constant sounding separation along track, resulting in a dense sounding pattern on the seafloor.
Clean and high resolution data
Due to the sector transmission technique, the system produces a strong dampening of multi-bounce interference from false echo, resulting in significantly cleaner data. Near field beam focus is applied in real time, both during transmission and reception. Due to sector transmission the focal point will be individual for each sector, resulting in a much sharper transmit beam over the entire swath. On reception, the focus is done dynamically for each beam. The result is a much higher resolution representation of the seabed.
The KONGSBERG EM systems
The EM 124 is part of the new EM platform designed for future challenges and uses the new KMALL datagram format. The format supports several new features, such as extended backscatter calibration, with more features in continuous development. The new format is supported by the KONGSBERG Kognifai digital open ecosystem, bringing opportunities to transform survey operations through digitalization.
Like all KONGSBERG EM multibeam echo sounders, the EM 124 ensures the best operating environment to safeguard marine life inhabiting the survey area through the option to decrease emitted sound levels.
