Vitino's location in the White Sea, ice-bound for much of the year, means a long trip round the massive Kola peninsula. Ports on the Baltic or Barents Seas give readier access to European markets, as does Russia's pipeline network.
The coast around Murmansk has become a key oil export outlet for Russia as it struggles to squeeze out booming output that hit post-Soviet highs of over 9.4 million bpd last year.
And it is likely to be central to Russia's plans to boost energy exports to the United States as it provides an unfrozen and quick route to the US east coast.
Vitino plans to take 100,000-tonne tankers from August, when it finishes a programme to deepen approaches. But growing regional exports may not benefit the port.
