Russia Rosneft calls its largest ever crude tender

MOSCOW, Feb 20 (Reuters) - Russia's top oil firm Rosneft ROSN.MM has called its largest ever tender to sell crude oil, changing the usual three month term to six months and inviting a total of 11 majors to bid, trading sources said on Wednesday.

State-controlled Rosneft is offering a minumum of 1.0 million tonnes and a maximum of 8.0 million in the second and third quarters of 2008 from the Baltic Sea Primorsk port.

In the south, buyers can bid for 0.5-3.5 million tonnes from berth one in Novorossiisk and 0.5-2.5 million from berth 2 in Novorossiisk or Yuzhny.

Invitations have been sent to Gunvor, Shell, Vitol, Chevron, BP, Total, Exxon Mobil, Eni and Statoil, as in the previous tender. Neste and Marubeni are among the newly invited firms.

Gunvor won the largest part of the previous tender from Primorsk with Shell coming second. In the south, Gunvor also came first with Vitol coming second and Chevron third. (Reporting by Dmitry Zhdannikov; editing by Anthony Barker)
