Two new detection units added to ORCA… and counting

November 20 – It was night and day again. The work continues around the clock when you are at sea. The second detection unit was also deployed, connected and tested last night. After that, unfurling was performed for the two detection units. A final test was then made from the shore to check that the two units are ok even after unfurling, et… voilà:  ORCA is enlarged to 8 detection units.

The campaign is now continuing with deployment of the next detection units; a third one is already on the sea bottom, connected and tested. A fourth one has been deployed in the evening: we will keep going until the deck is empty or the weather changes (the forecast is not ideal for next week): which of the two will happen first?

After unfurling of a detection unit, the launcher vehicle on which the unit is installed for deployment reaches the surface and is recovered for next campaigns.
