Kongsberg Upgrades Its Multibeam Echosounder
Kongsberg Maritime has released two new state-of-the-art features on its EM 2040 MKII multibeam echosounder.
The first enables the use of dual high frequencies to survey wide swaths of the seabed at much higher resolutions than before, while the second facilitates simultaneous collection of back scatter data using multiple frequencies.
The EM 2040 MKII is a broadband multibeam echosounder system, which uses frequencies from 200kHz to 400kHz to yield a wide swath of up to 170 degrees. With the new high frequency feature, the EM 2040 MK II will additionally employ 600kHz and 700kHz frequencies to give enhanced detail over a swath of up to 120 degrees. This will enable the user to carry out bathymetric survey, inspection and wreck mapping at the highest resolution possible today. Seabed classification will also be more accurate due to the added ability to simultaneously collect back scatter data at multiple frequencies – an enhancement of the single-frequency facility standard to all EM systems.
As part of a new EM technology platform designed for future challenges, the EM 2040 is compatible with a new Kongsberg-developed datagram format, which supports several new features such as extended back scatter calibration, with more features already in development. The new format is supported by Kognifai, Kongsberg’s open digital ecosystem which brings opportunities to transform survey operations through digitalization.
The EM 2040 is a mapping system that takes advantage of features and benefits achieved in the development of the EM family of multibeam echosounders: EM 712, EM 304 and EM 124.
