In the 2D configuration, the HR seismic system comprises a Sercel Sentinel RD streamer of 600 m or 1200 m, with FDU spacing of 6.25 m, amounting to 96 or 192 FDUs.
In the 3D configuration, the HR seismic system comprises two Sercel Sentinel RD streamers of 600 m, spaced 25 m apart. The streamers are towed from two booms extending from either side of the ship.
Data acquisition is achieved through the use of a Sercel SEAL 428 v2 acquisition system. Data is recorded in the SEG-D format.
The navigation system used is the ECOS system developed by Genavir.
The depth of the seismic streamer is controlled by ION streamer depth controllers (Compass Bird 5011-2) positioned every 150 m along the seismic streamer.
A buoy fitted with a GPS system enables the position of the streamer tail to be established.
