Kraken Robotics Inc., Canada’s Ocean Company™, announces that its PanGeo Subsea subsidiary has completed cable depth of burial (DOB) surveys along the EstLink 1 and 2 cables during an offshore campaign utilizing PanGeo's SeaKite ROTV equipped with the patented Sub-Bottom Imager™ (SBI). With a strong history in supporting sub-seabed surveys for offshore wind and offshore energy, PanGeo has completed more than 10,000 kilometers of cable DOB surveys to date.
PanGeo supported marine survey provider Arctia Meritaito Ltd onboard the research vessel RV Mintis to conduct cable depth of burial along the two interconnector cables that join Finland and Estonia's electrical networks. The 350MW EstLink 1 was installed in 2006 and crosses the 75km wide Gulf of Finland, reaching a maximum water depth of 100m. EstLink 2 is a 650MW, 145km cable installed in 2013 and is ~ 70km east of EstLink 1.
