KONGSBERG DISCOVERY | Innovation

SIMRAD More than 75 years of innovation SIMRAD's slogan is “Technology for sustainable fisheries” and we live by this slogan every day. SIMRAD believes that a sustainable fishery worldwide is the only right way to survive. By sustainable we mean a healthy take out of the world fish stocks as well as an efficient and profitable fishery for the fisherman. SIMRAD believes that technology is an important factor to achieve this. Products that we believe have contributed to a sustainable fishery are Echosounders with a split beam technology: this makes it possible to catch the right size fish. Gear...

The SIMRAD brand name is owned by the Kongsberg Group, a Norwegian technology company. The Kongsberg Group has a strong position in the maritime sector through its company Kongsberg Discovery (KD), where the SIMRAD brand name is sold from. KD manufactures products like MRUs (Motion Reference Units), high accuracy surface and underwater positioning systems, multi and single beam echosounders, sonars, autonomous underwater vehicles (AUVs) and uncrewed surface vessels (USVs), as well as all the SIMRAD products. • First TrawlEye (FH, cable based) ll 1968 • First sonar with hydraulic hoist (SU) •...

History SIMRAD was founded in 1947 by Mr. Willy Simonsen. The name SIMRAD derives from “SIMonsen RADio” and, as the name indicates, it all started with radios. But this shortly developed into echosounders and sonars. Today, SIMRAD is recognised all over the world for premium performance products, manufacturing sonars, echosounders and Gear Monitoring equipment. • First composite sonar (SC90) 1992 • First Trawl Sonar (FS3300) • First multi frequency sonar (SP270) 2002 • First composite transducer • Fishery sonar with Hyperbolic FM technology (SX90) 2017 • First matrix sonar for trawlers • CS90...

SIMRAD is one of the very few producers of transducers. The transducer is an important part of an echosounder's performance. A transducer is the combination of a microphone and a loudspeaker, all in one. The transducer is converting electrical energy into sound waves and vice versa. What you see on the echosounder screen is actually echoes from transmitted sound. 8 KONGSBERG DISCOVERY | Transducers

From electricity to sound The transducers' ability to convert electrical energy into sound depends on how it is built. The better it converts, the better the transducer is (and the echosounder performs better). There are several ways to make a transducer with different materials that can be used. Today, ceramics is the best material to use, seen from a performance view. Other materials such as nickel or ferrite have a lower price but will not convert electrical energy as efficient as the more costly ceramic material. Also, the way the material has been used in the production also matters to the...

SIMRAD makes a wide spectre of transducers and hydrophones to fit various echosounders frequencies and configurations. We can divide the transducers in three categories: A single beam transducer will give you the normal information expected from an echosounder, like a school of fish, depth to bottom, separation of target from bottom, etc. It is still a must to have a high quality “We are at the forefront of performance through innovative design and a unique production technology.” Value Chain Manager transducer to get a good picture on the echosounder. SIMRAD has many single beam transducers...

A wideband transducer is a transducer that can transmit on a wide frequency range, for example 50-110 kHz, 100-160 kHz or 160-300 kHz. This means you only need 3 transducers under your vessel to cover a frequency range of 50-300 kHz. To make a transducer that is capable of doing this, composite technology is the best suited material to use. All SIMRAD wideband transducers are produced with composite material. With the SIMRAD wideband transducers, it is possible to make sweep transmissions (sending out starting at a low frequency and go up), chirp transmissions (FM transmission where the echosounder...

Acoustic Synchronisation Unit TU40 The key to achieve a sustainable fishery is the ability to perform a preliminary evaluation of the fish schools. The best way to evaluate those fish schools is by the use of acoustic equipment, like echosounders and sonars. The new generation fishing vessels have more and more acoustic equipment working simultaneously to have as much information as possible to take the right decision. Imagine all those equipment transmitting pulses in various frequencies, with various strengths and pulse durations. In case that these acoustic waves were visible, we would see...

Silence, please! which allows monitoring of status, modifying settings, trigger schedule as well as performing diagnostics. The Trigger Unit does not need the software application running. Once configured, the TU40 will work in the background, organising the trigger sequence automatically, with an intelligent algorithm assuring the fastest ping rate for each equipment. The TU40 consists of two main components: • TU40 top side software application (typically run from existing computer onboard). • TU40 synchronising (Trigger) Unit that interfaces with the acoustic systems. The TU40 application...
