Restructuring of oil trade routes has caused a shortage of tankers, and it is impossible to fill it instantly, said Igor Tonkovidov, General Director of Sovkofmlot. Only way to avoid the deficit of tankers is to produce vessels of this type in proper quantity or to buy them where it can be done. Thus, Sovkofmlot continues to implement the announced program of tanker construction at the Zvezda shipyard, and is also studying other opportunities for acquiring vessels.
