"Tiger is controlling the sweep process, particularly the sliding of cables between the submersible and the nets it was caught in," Igor Dygalo said.
A second Tiger apparatus will be delivered to the scene soon.
Specialists from the Tetispro company, who deal with the technical maintenance of unmanned deep-sea apparatuses, left for Kamchatka to jointly cooperate with the Pacific Fleet specialists in the rescue operation, Dygalo said.
There are seven sailors on board of the submersible.
According to doctors participating in the rescue operation, exiting the hatches and swimming freely at 200 meter-depths is highly risky and is only done when people's lives at stake.
"We have ample time for more effective and less risky steps," Dygalo said.
