The EM 302 transducers are modular linear arrays in a Mills cross configuration with separate units for transmit and receive. This sonar offers significantly larger swath width, increased data density and resolution. Beam focusing is applied both during reception and transmission. The system has up to 288 beams / 432 soundings per swath with pointing angles automatically adjusted according to achievable coverage or operator defined limits. In multi-ping mode, 2 swaths are generated per ping cycle, with up to 864 soundings. With multi-ping the transmit fan is duplicated and transmitted with a small difference in along track tilt. The applied tilt takes into account depth, coverage and vessel speed to give a constant sounding separation along track. The beam spacing can be adjusted as equi-distant or equi-angular. EM 302 uses both CW pulses and FM sweep pulses with pulse compression on reception, in order to increase the maximum useful swath width. The transmit fan is split in several individual sectors with independent active steering according to accomplish compensation for the vessel movements: yaw, pitch and roll. The high density, high resolution, large coverage and water column capability makes EM 302 an ideal system to explore the sea bed and the water column for detection and characterization of a broad spectrum of features. EQT200817_EM302 completed Fugro Equator Fugro Equator (EQT) MV Fugro Equator is a survey vessel owned and operated by Dutch company Fugro to provide a range of offshore survey capabilities. The vessel can carry out a full range of offshore survey services from simultaneous analogue/digital site surveys through to route surveys. In addition, a Fugro owned AUV system can easily be mobilised on the vessel without affecting other survey capabilities. ROV Inspection and more complex Geotechnical spreads can be mobilised as required. Permanently installed equipment includes digital seismic, seabed and sub seabed mapping systems.

Important deep water system features included with the EM 2040 are dual swath per ping (EM2040D) to allow a doubling of survey speed, FM chirp to achieve a much longer range capability, complete roll, pitch and yaw stabilization, and nearfield focusing both on transmit and receive. The EM 2040 is modular, allowing the user to tailor the beamwidths to the operational requirements, 0.4 by 0.7 and 0.7 by 0.7 degrees. The operating bandwidth available on the EM 2040 is unprecedented, from 200 to 400 kHz, which is a full octave, and this is achieved with the standard transducers. The operator can thus choose the best operating frequency for the application. The EM 2040 is well suited for surveys meeting the IHO-S44 special order. The standard depth rating of the EM 2040 subsea parts is 6000 meters. The system is ideal for operation on subsea vehicles such as ROVs or AUVs. The transmit transducer has an angular coverage of 200 degrees (±100 degrees) as standard, allowing a coverage of 5.5 times water depth when matched with a single receive transducer. Adding a second receive transducer allows surveying to the water surface or up to 10 times water depth on flat bottoms.
