A replenishment oiler or replenishment tanker is a naval auxiliary ship
with fuel tanks and dry cargo holds which can supply both fuel and dry stores
during underway replenishment at sea. As the Soviet Navy began to more regularly
operate in large areas of the world's oceans and because of the emergence of the
Kiev-class aircraft carriers, demand for large surface supply ships increased.
For these purposes, also were used civil tankers who transferred to the Navy.
The Olekma class is a two civil fleet replenishment oilers (Olekma and Iman) built
in 1960s for the USSR in Finland as part of a large series of civilian tankers
of the Drogobych type.
The maximum length of the ship is 105,4 m, the maximum
width 14,8 m and draft 6 m. When in standard load, the ship has displacement about
2,040 tons and 6,480 tons while fully loaded. Endurance of the ships is 20 days
during which they can travel the distance about 4,000 nm. The oilers of this class
are equipped with a device for the transfer of goods in move by the traverse method.
This allows carrying out cargo operations during significant sea waves. Capacity
