From now on the “Innomar smart” SBP model comes in a rugged housing (IP65). This reduces the weight by 30% and no extra transport case is required, which saves shipping costs due to 55% less transport volume and nearly 60% less gross weight.
Transducers have not been changed with both models.
As with the other new SBP generations, the term “SES-2000” has been removed from the model name.
Innomar “smart” Sub-Bottom Profiler
The Innomar smart model is the smallest member of the Innomar sub-bottom profiler family. It has been designed for inshore surveys in shallow waters down to 100 metres water depth using small boats, but can also be used in coastal areas.
Because of its small size and weight this system is convenient even on the smallest boat and on uncrewed remotely or autonomously operated vehicles (USV/ASV). The topside unit is controlled via Ethernet (LAN / WiFi) using any Windows based PC or tablet.
The Innomar smart model acquires full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the Innomar SBP data.
This model has been first launched as “SES-2000 smart” in 2017, the latest generation has been introduced in 2020.
The Innomar smart model is utilized on the Innomar autonomous uncrewed surface vehicle (USV) for remote-controlled and autonomous surveys in sensible environments.
For survey examples please see the Extremely Shallow Water Applications and Shallow Water Applications.
