Zhongolovich, N.I. Evgenov, S.A. Yanchenko, Yu.K. Chernyavsky and others. 
In the last pre-war years, Vorobiev led expeditions on the icebreaking steamers "Sadko" and "G. Sedov". The last post of him and found the war. A few days later, Captain 3rd Rank Vorobiev arrived in Tallinn to continue his service in the hydrographic department of the Baltic Fleet. On the ship "Hercules" he participated in the dramatic Tallinn crossing, hydrographic support of the fleet's actions in the defense of the Hanko peninsula. During the entire blockade, Vorobiev was in Leningrad and Kronstadt, participated in the hydrographic support of combat trawling and mine settings, aerial photography of minefields, and artillery instrumental reconnaissance. In 1944, after leaving the war in Finland, he was assigned to the new naval base Porkaludd, where he was in charge of the navigation equipment of the naval fairways.
