Abstract
The article dwells upon the problem of developing offshore oil and gas fields around the world accompanied by producing not only stationary and semi-submersible rigs and drilling vessels, but also a large number of auxiliary vessels for various functional purposes. It would be impossible to extract offshore hydrocarbons under the sea bed without them. Special fleet was formed during the years of development of offshore oil and gas fields in the Russian Federation, the part of it being imported. In the upcoming years, our country will face some challenges related to the development of Arctic reservoirs which are mainly located in the long-frozen deep seas. Their development in deep water will only be possible with auxiliary fleet, as it will be necessary to build deep water drilling vessels and other facilities/vessels. The types of vessels of the modern oil and gas fleet are presented, depending on the area of navigation, the depth of use and the specifics of the work performed. It is noted that currently in world practice there are no examples of using proven drilling and production technologies in severe ice conditions, when ice thickness exceeds 2-3 m, because the modern ice-resistant stationary platforms can not withstand the load at a depth of more than 80-100 m. The auxiliary fleet will both service offshore rigs and ensure their long-term productivity and functionality. For the development of oil and gas fields in the long-frozen Arctic deep-sea areas it is necessary to create a full-fledged underwater oil and gas fleet.
