Kongsberg Maritime has introduced a new multibeam echo sounder designed for survey and inspection operations in shallow and medium water depths. The new KONGSBERG EM 712 multibeam echo sounder is
the second generation of wideband multibeam for these water depths. Delivering highly accurate results through superior range and resolution to all relevant survey standards, the EM 712 supersedes the
EM 710, which is well established as the de facto standard for all shallow to medium surveys. All users of the EM 710 will be offered an upgrade path, making it easy to integrate the EM 712 into their
The EM 712 is based on a sophisticated, flexible hardware platform, which enables several performance enhancing features. One of the key benefits that the re-engineered system introduces is
increased range performance, which is close to double that of the EM 710, resulting in a maximum range of 3600m and a swath coverage of close to 4000m. Other advances include low-noise receiver
transducers and electronics in addition to a smaller, lighter form factor, enabling for more flexible installation on a wider variety of vessels.
Ensuring that the EM 712 can support the same wide range of applications as the system it replaces, it is offered in multiple versions, including a 0.25 x 0.5 degree system for the best range and
resolution and a smaller, portable 2 x 2 degree system ideal for use on vessels of opportunity. All models are available as full versions for maximum range performance, or as a shallow range version
without FM chirp enabled. Kongsberg Maritime has also developed an 'entry level' model, with reduced depth performance.
The first generation of the EM 710 was released in 2005 and quickly became the standard for shallow to medium range surveys. It was the first true wideband system and the first multibeam echo
sounder to utilise FM chirp as a transmitting pulse. By introducing these and other features the EM 710 started a paradigm shift in multibeam development. The EM 712 is a natural progression, which
improves on the ground-breaking EM 710 in every way.
"Today all KONGSBERG EM multibeams use FM chirp and have an unparalleled range and resolution," says Helge Uhlen Director of Sales – Subsea, Kongsberg Maritime. "The EM 712 joins our unmatched
range of industry and technology leading MBE systems, which includes models for very shallow water with very high resolution to large systems for full ocean depths, all in different sizes and shapes
to fit any application. All of our multibeams have gained a reputation for being highly reliable with the very best performance available and the EM 712 certainly lives up to what is expected of a new
