VNIIOkeangeologia has a UMB-130 off shore drilling complex (multi-track drilling rig) comprising: ANB-50 drilling pump unit, bottom frame, elevator for lowering and lifting the drill shell, bottom frame winch, winch for the drill shell, PBS-127 drill string, set of core-boring and drilling tools. The UMB-130 complex is manufactured and operated in close cooperation with the Donetsk National Technical University (DonNTU). In 2006, the complex was used for geological surveys in the Chukchi Sea from the sea tug “Shuya” [1, 2]. In 2007 the complex used for Laptev Sea cryolithozone study with the R/V “Ivan Petrov”. Wells in the Chukchi Sea have drilled the Holocene marine silts and Neogene sediments (see Fig. 1 below), Laptev Sea wells reached pre-Holocene lake sediments. The experience with this complex showed the possibility and performance of its use for marine geological exploration, especially for the Arctic seas.
