Sulmara is one of a few US companies to offer ERT data to support Offshore Windfarms

With the vessel moving forward at about 0.5 - 1 knot and a measurement performed approximately every 3 seconds for a duration of 800 ms (0.8 sec). The results give a new reading approximately every 1 meter of travel. This dense sampling allowed for some data clean-up and meaningful information for the client’s engineers which improved efficienceis.  

Conditions in Reynolds Channel were also very challenging with strong tidal currents, little manoeuvrability, and winter temperatures which would cause the topside controller to freeze up and miss measurements. After each profile, the data was checked and if measurements were missed then the profile would be rerun. We also made physical adjustments to the setup which mitigated the dropped measurements due to the cold temperatures.
