It is a platform for the realization of oceanographic works in coastal areas, developed on a vessel of 8.5 m in length.


Its hull combines a rigid submerged structure of low draft and a high resistance pneumatic float, which gives it great flexibility in maneuvers. This allows INNDAGA to operate safely, in areas where other oceanographic vessels can not access (rocky, port areas …).


It also has a closed cabin that houses the consoles of scientific instrumentation, permitting a normal and safe activity with sensitive equipment even in adverse environmental conditions, besides the presence of a generator of 3KVA generator of 3 KVA, which grants electrical autonomy (220 / 12V) to the entire platform.


The INNDAGA also integrates a small crane with a load capacity of up to 200 kg, which facilitates the handling of small scientific instruments.

  • Determination of the background quality

  • Elaboration of bathymetries and detail cartographies

  • Definition of thickness and type of sediment

  • Characterization of oceanographic conditions in subtidal areas

  • Monitoring and quality control in dredging operations

  • Stability assessment of maritime works and movement of blocks

  • Location and positioning of submerged structures and objects

INNDAGA is equipped with scientific instrumentation with the highest performance in the market:

  • Trimble SPS DGPS positioning system
  • Side Scan Sonar Klein 3900
  • Multibeam Kongsberg GS +
  • Inomar Compact 2000 Echosounder

  • UWITEC tester (60 and 120 cm tubes)

  • Van Veen Dredger (Capacity 500 cm2)
  • Niskin bottles
  • CTD s XRX- 620 and SBE 37-SMP MicroCAT
  • YSI portable multiparameter probe

It is a high resolution digital side scan sonar. The model has a double frequency capacity, 445 kHz that offers excellent range and resolutions and 900 kHz that offers a higher resolution of the identified objects.


It has a sweep range of up to 150 meters to low and 50 meters to high resolution. It also allows the characterization of the seabed and as well as the search and recovery of submerged objects.

Bottom profiling It works at depths smaller than 400 m and with a penetration in the sediment of up to 40 m and with vertical resolution of 5 cm. It allows the realization of high resolution background profiles and penetration in the seabed

It is a very versatile multibeam sonar, ideal for working on small boats and simultaneously offering a bathymetric sweep and a side scan mapping of the seabed.


It can work at 3 different frequencies (125, 250, 500 kHz) and offers coverage that can reach up to 12 times the depth.


It generates high fidelity background images allowing the subsequent elaboration of cartographies and bathymetries with centimetric resolution.

Taking of stratified cores, as well as samples of surface sediment from the seabed or water from the column

Equipment for the sampling and measurement of oceanographic parameters of the water column, such as temperature, pH, dissolved oxygen, pressure, turbidity, speed and direction of the current in the water column.
